Is Time Travel Really Possible? | World’s First Time Machine | Spark 

As a shut-in, disabled vet I want to say how much I appreciate your fine programs. I love studying history and science and it's channels like yours that help bring the classroom to my bedside. Keep up the superb work!

I have been time travelling for 74 years ...the past was a lot more interesting than the present and the future doesn't look so hot either.....Just enjoy the ride , you only get one ticket....!!!

My Uncle Paul became my everything after the death of my Father. I was 6 when my Dad died from cancer. My Uncle Paul was my sanctuary and then one night there was a crash in the back of the house. It was my Uncle falling down dead from a heart attack. I was 11. It turned my already fragile existence into chaos. Also my Mother had died from polio when I was 1 1/2. So after my Uncles passing it was me and my Aunt. She only survived 4 years after my uncles death. I was orphaned at 15 1/2 and on my own ever since. What does this have to do with time travel? I don’t know, but hearing about the death of this mans father when he was 10 caused me to relate and reflect.

How to time travel: Step 1: sit in a chair Step 2: look at a clock Step 3: wait You are now traveling 1 minute per 60 seconds

“Has it ever struck you that life is all memory, except for the one present moment that goes by you so quick you hardly catch it going?”― Tennessee Williams

“Time is flexible.” Tell that to my boss 😅😂

I wanna go back and try and save my Fathers life...He was my best friend. God bless 🙏 🙌 ❤

I remember watching this documentary over 10 years ago. Either in Odyssey or the History channel. Terrific stuff. Hope Mallet does it someday.

I have been time travelling all my life. At night I go to sleep and when I wake up it's the next day!

Time travel is happening right now. We are all travelling forward in time. What we need is to find a way to control it so we can go forward faster or go back.

Brother if you achieve time travel not only will your father be proud of you so will the world !

When I heard Professor Mallett talking about his father dying at such a young age and that’s why he became involved in time travel, it was absolutely heartbreaking. Imagine him as a little boy wishing that he could go back and save his dad. The death of his father, shaped his future. What an intelligent and fascinating man he is. I would love to sit and talk with him to listen to all of his thoughts and ideas….what a fascinating mind he has! It would be so interesting and exciting if we could time travel, however, what kind of circumstances would we have to face…both good and bad? Very interesting documentary.

Paradox could be answered by alternative timelines. Essentially, you travel back in time and kill your father. The second you kill him, he suddenly ISNT your father, and you essentially killed the "wrong" person, though it was the right person. Edit: Hey! Cool, I said that before they started talking about freewill and subatomic particles and parallel universe overlapping.

Recording devices audio/video are actually time machines, we can view and listen to the past but can't change it.

If can travel back in time would relive my childhood

time is like a river, it can slow down and speed up but its always moving forward......

If there is ever a real time machine, time tourism would be huge. An opportunity to relive history as it happened.

CS Lewis speculated about time travel in his unfinished work "The Dark Tower." In this book, he speculated that time travel could only work going forward in time. The inevitable paradox makes backward time travel impossible.

Every time you experience Deja Vu, somebody has time traveled, and done something that altered events in your timeline that effected your reality. Time has an auto correct effect that does not revert things back to the way they were, but corrects the timeline to the change that occurred in both directions.

Ron - Builds time machine and goes back and saves his father Ron - His father is alive so he never builds time machine Solve the Paradox!

We all have time machines,what takes us back are memories and what bring us in future are our dreams.

Indeed, it would be a very important piece of technology. Time travel. Be careful of the butterfly effect though.

This would be fascinating! Going back in time, and being able to participate, could cause problems to the traveler, causing him or her to return to another (multiverse or parallel universe). To return to one’s own universe, no changes could be made. The traveler could only observe unseen, somehow! Once we learn how to bend spacetime by creating a wormhole or find another way to warp space, enabling us to go faster than light speed, if ever, would time travel to the past (or future?) be a real possibility. It will also be possible to transport anything (not just electrons) from people and other life to inanimate objects) instantly. This, of course, would be in the far future, as we are not even a type 1 civilization, or close to it, yet. We have had aliens, beings from elsewhere in the universe and multi-dimensional beings from other universes (perhaps) visit the earth and keep tabs on our progress, etc., that are many thousands and millions of years more advanced that have achieved the above knowledge and skills to travel to the earth. They could never have travelled here without having mastered advanced skill and craft and devices to do so.

I’m from 1971; it only took me 47 years to get here.

please send me back to a time when there were no bloody adverts every 2 seconds,

THE TIME MACHINE by H.G.Wells is my favorite novella and subject of all time How I wish I could go back to July 1977 an re-experience the sheer joy of this reading experience

making our present time in good choice, we dont need a time machine, if we planned and do great things in present time we have, we must embrace our present time now...

“Nothing can be loved or hated unless it is first understood.”― Leonardo da Vinci.

I can travel through time. But so far I've only figured out how to go forward.

We already have the most effective time machine, our minds.

Problem with time travel is same as problem with ftl navigation. Simply going to past can generate alternate realities. If you try to go back to present you'll probably get stuck in that alternate universe. You'll wind up like the characters in TV series sliders

If a time machine could be made, it already has been.

I LEARNED so much about time in the first 30 minutes... I realized I was wasting mine.

I love stories about time travel, I have since I was a kid and some of my favorite movies center on time travel. I would love to go back in the past and change certain events, I think most everyone would, but alas, time is linear. You can skip ahead I suppose if you travel fast enough but moving in the other direction would create loops in the continuum and the universe seems to know that and will not allow it. Let's say I travel back in time. My new self would have to stay on that path, but when the time came I would have to travel back again, and again, and again in order to make that happen. It's like the final scene in the movie Twelve Monkeys. Madeline Stowe looks at Bruce Willis as a child and smiles because she knows, even though Bruce is lying dead in front of her, that they are going have another kick at the can the next time they send him back. I know, it sounds a bit off, but it's either that or you create an entirely new reality with each visit, which is even stranger. No, I'm afraid such conundrums are why time travel to the past is a universal no-no. Time is really a human construct anyway since we use it as a measuring device. When we leave this plane it loses its utility and ceases to be. But like I say, I still love a good time travel story.

nice program: first time I've seen and heard two leading narrators with outstanding pronunciation using English grammar. The lady narrating while escorting children in a time travel museum going to and talking about the different Exhibits. While the children are in the exhibit the other narrator confirms the lady tour guides introduction in the new Exhibit and edifying other speakers talking about the children what they may expierence subject matter about Exhibit. Great presentation and video for all ages to enjoy - and most importantly understanding all speakers:)

Once again, I've just travelled back in time to 2003, just for a short while, to hear once more the smooth as butter, velvety tones of Tom Baker.. Now that's what I call Time Travel. 😉👍

The concept is outrageous. If you traveled in time, you cant escape the fact that youd have done it in the present. If time is a location to travel to, then all of it exists all at once. All time happens ...all the time

According to what the professor has said all we need to find is a stable black hole that has been around for millions or billions of years and we could travel back-and-forth in time to any point since it was created, Essentially since it was turned on.

I already told mallet ten years ago that although a small time window could be created using light, it would be far too small to be a functional time travel window. Maybe he might be able to send a mouse back in time. Ronald just completely ignored my advice and help, so I don't feel bad saying it's not going to happen for him.

Professor Mallet please know that, even if you never accomplish another thing, your father is already proud of you. You’ve surpassed most parents wildest dreams for their children!

I do travel in time within my memories.i do go back in my mind and i do materialized with my feelings.that's how i go back in time.and the future looks so dark for human kind and the planet that i don't even wanna know what tomorrow brings.

I Time Travel every night, I go to sleep then a few minutes later I wake up in the next morning! ✅

when i was a very little girl i suffered from frequent nightmares. At the foot of my bed was a cross on the wall. i vividly remember that one night i prayed to the cross that i could just blink and it would be morning so i wouldn't have to dream that night. I stared at the cross and blinked and suddenly it was daytime when i opened my eyes. i freaked out because the sun was fully shining on the cross and i wasn't even yawning or stretching like you do when you wake up. I remember being fully cognizant as I had been trying to control my state of awareness in those days so that I wouldn't get stuck in a bad dream while asleep. All i did was blink. Either i fell into a very deep sleep as soon as I closed my eyes, God knocked me out, or I dunno maybe I time traveled??? who knows. it was my usual bedtime and I was not exhausted or sleepy that night. i was never able to do it again. i didn't tell my parents because i thought they were going to get mad at me since I felt that I technically didn't fall asleep like they told me to.

Looking at what I've achieved so far if I had to time travel, I would go back and do it again to make the story even more beautiful.I am 68, man about town,owner of my own car(wheelchair)

If I could I would never travel BACK in Time but FORWARD! I'm 74 and would love to be around to see the future.

If Ron builds the time machine and saves his dad he won't be inspired to build the time machine and can't go back in time to save his dad. Paradox

I can really add to the perfection of a time travel/machine.

The grandfather paradox doesn't apply because if you did travel back in time (assuming it was possible) you'd be creating a different version of that reality; an additional time-line. The original time-line would remain unaffected.

If time travel is possible in the future, then what if the past has already been altered without us even knowing it?

Dr. Mallet is a beast! His genius, intuition, and persistence is paving the way to do the "impossible!" Similar to the way people thought that flying was never going to happen, until the Wrights did it, this man will also pave the way for remarkable technologies and applications. Thank you, sir!

I believe time travel was achieved at some stage, i had a schematic on how to build a time machine many years ago that was mysteriously corrupted along with some other files. The only details of its construction i can remember is that a titanium frame or box would need to be constructed and painted with either copper or gold paint. it explained that in order for it to work you would have needed to generate a huge amount of power including creating positrons and anti-positrons into the field or 'portal or box. There is also the issue of the Earth itself, weather or not it is stationary or if it is barrelling through space at 60,000mph along with the solar system. I believe the machine would work on a stationary earth rather than one that is moving through space because the calculation of locality would be impossible.

I want to go back and try to save my mother I miss her so much🙁☹️

Their description of time travel sounds very much like what happened during the Philadelphia project.

We need to go back in time and retrieve the knowledge lost at the library of Alexandria in Egypt

I was thoroughly impressed with this video and I just subscribed to ur channel. Job very well done on the detailed research to produce this video. Looking forward to more content 👌 😊

If time travel is possible then I believe we are already doing it, the head wrecking fact is that because it's time travel and you can travel to the past which infact is NOW, so it's not difficult to believe time travellers are already among us. And if we can change anything ( the butterfly effect) nobody would know because we would start to remember differently because we wouldn't know that anything had changed, so for "us" we are living a completely normal life. Maybe some people would remember which would totally mess with their heads, so if someone is seeing the world as time is being changed, could you imagine what messing with someone's mind to that degree would be told they are insane and probably get locked up. Maybe people who are from the future ( a few people have made this claim) shouldn't be dismissed as crazy they should be investigated. Deja Vu could be when "time" has been adjusted. (Something to think about) if you have ever remembered anything differently maybe your memory's recollection could be real and really happened but has been changed . ( I did say this theory was head wrecking. ) if you get this far let me know. Thanks in advance if you actually got his far.

I swear the narrator is Tom Baker, also narrates Little Britain (can you not hear it?): “When people in Britain want to buy a pet, they go to a pet shop. If they want to buy a pet shop, they go to a pet shop shop. If they want to buy a pet shop shop, well, they're just being silly.”

I'm from 1965, it takes time for development and the 54 years of my life is just about as one drop in the Atlantic and Pacific 🙏🏾😉

As fascinating as time travel is (as an idea) it would ultimately dismantle all of humanity. The ONLY way this wouldn't be detrimental is if somehow, you were able to travel and witness things with your body invisible. Maybe traveling through your thoughts. Im not sure if people truly grasp how bad it could be with ANY change to ANY situation that has already happened. For example, five days ago, I hit a deer with my car. Not only did that effect me, but It ended the deers life. This deer that could've spawned many other deer, this deer that could've gone on to run in front of someone else. I called a tow truck, this man took time out of his day to get my vehicle and I rode with him and had a great conversation.. What would have happened to him if that call was not made..If I had gone back in time and for some reason manipulated this situation? What incredible change couldve fallen upon him had I not called? Maybe he would've wrecked on another call? Maybe he would've been called to some other spot and witnessed something gruesome that changed him forever? ANY tiny effect on time will have a spider web effect on thousands (maybe millions) of people down the line. Every tiny change in EVERY SINGLE SITUATION effects everyone. Even down to someones thoughts. If TT does come about.. it must be heavily regulated.

I'm loving it. Traveling into the "outer regions" of a black hole where time and spaceare dragged along and then get out. One would need an energy source that is greater than the black hole. Wait, that would mean to cary another black hole with you. But wouldnt you then be sucked into either black hole? And what about the two black holes merging?

I just Time Traveled two years into the future to watch this.

Why does everyone one think we need a "machine" to travel through time?

Hey, guys... Dr. Mallett is a real genius. He is a friendly and sincere man. A man like Dr. Mallett deserves a second chance. We should never take for granted that our parents are alive as we watch Dr. Mallett's documentary. Even though he said that the time machine only works from the time when it is on, only the time will tell if we would be able to go back in time before the machine would be turned on. I am sure there is a way that the machine will work to help Dr. Mallett to rescue his beloved father, guys. Let's keep praying for this! Don't lose your heart!

Well if you are going to use Einsteins special relativity theory as a backdrop , it already states that no object can attain the speed of light without becoming infinite mass requiring infinite energy. So like the song says "Dream On".

It would be interesting to travel down every variant that we find, all the forks in the road we could travel down and what we would become if we went down each fork. I can imagine that with the multiple relationships I've had with many people. What if I had traveled a different road. I would love to have the time to travel down each of these to see what would happen.

I myself am a time-traveler, hurtling into the future. One way only, baby!

Its not hard to go back to past where you have been there..but its hard to go to future where you haven't been there..but you can travel back to past only to your own past, your own trial you leave behind each passing time if not you will end up in another parallel universe where you dont exist 😀

Time Machine is a open doorway channeled like finding a radio station or TV station... But you would need so many things to do this... First a special force field to protect you and your craft. Then atomic energy because of the power needed.. Then a reaction projecting you in time...or distance..

If there is a time machine i wanna go back to the 1980s... Plz send me back NOW!

Hey, the former head of the Skunk Works said, "If you can imagine it, we already have it."

The biggest problem is how, even physicists, end up going down a rabbit hole of using fictional things to justify their theories. They also only describe relativity from the perspective of one angle. Time isn't a physical dimension. It's just a way of predicting and describing movements. If someone moves a box from one location to another. Then they move the same box back to where it came from, that doesn't mean the box went back in time. One thing no-one ever seems to take into account for the supposed speed of time difference when moving fast is the inertial effect of gravity on the tools being used to measure time. It's already been proven that gravity affects the speed of photons (look up gravitational lensing). The supposed time dilation caused by moving fast is more than likely gravitational drag. With one clock being on Earth; the source of the gravitational pull, and the other in space, of course there's a difference. If the same experiment were done with two clocks in space, under the influence of the same amount of gravitational pull, they would show the same speed of time, regardless of how fast they're moving away from another object. Speed is relative. In Stephen Hawking's book, A Brief History of Time, he pointed out that relative to each of us, we're each the centre of the universe. From our own perspectives, when any of us moves from one location to another, everything else is moving, not us. With the clock experiment, from the perspective of the clock in space, everything else is moving past it, while it is still. The clock on the Earth has it's own perspective. It's all down to the relativity of individuals. In other words, relative to a mid-point between the two clocks, the clock in space is not moving any faster than the clock on Earth. One part that contradicts the claim of time dilation, due to the speed something is moving, is their description of how we all have our own relative time, due to the speed of our own atoms. An easily testable example is to have two identical battery-operated clocks. One has fully charged batteries that cause the hands to move at a certain speed. The other clock as low-power batteries that cause the hands to move and a comparatively slower speed to the first clock. The difference in movement and relative time is due to the difference in the speed of electrical atoms. Relative to the third party viewing the clocks, neither clock is time travelling, as such.

Thank you for sharing this video it was very interesting & so fascinating. I have read Ron Mallet's book and it is a good one too.

I love the great Tom Baker doing an amazing job narrating, of course he understands the machinations of such things as a lord of time, thank you Doctor!!!

I cant see what all the fuss is about I've been time travelling for years. Its really easy to do all you need is a cup of mushroom tea

Going back in time is like trying to take a taxi an hour before the time it arrives, at that moment in time the taxi isn't there so you can't take it.. Going forward in time is like trying to step out of a taxi on a future timeline you never took because the taxi couldn't have been on your timeline in the past and be on another timeline in the future. I'm not saying that time can't be manipulated, but i am saying that you can't mix timelines without disrupting the balance or destroying something else. In my humble opinion...

Here’s something I don’t ever see anyone bring up: regarding possible parallel universes as a solution to preserving our timeline, if one travels back to the past and changes something, the idea is that a DIFFERENT parallel universe’s timeline is changed, right? So then my question is, who is to say that very exact thing didn’t already happen (even multiple times) to OUR timeline?? Seems like weird events in history could be explained as someone altering our past and we just didn’t know it. And further, what if Thai Mandela Effect of false memories rally IS real and that some past alteration to our timeline caused ripples in our dimension and resulted in some peoples’ memories being changed but not enough to actually forget the truth.

Personally, I think we have an inner-clock we are cognizant of. As children, time was slow and took too long to reach certain events and deeds. However, as time elapses to this present moment of a sixty-plus man, such as me, the speed of time appears to be on steroids. Now, I'm totally aware each day, week, month, and year(s) are a construct of strict measurements that can't be altered, yet I sense a change nonetheless. In fact, it appears to be normal for others too and we tend to be astonished by the same phenomena. While we tend to suggest to ourselves that youth is affected by the length of their life is ahead of them appears to be too long and slow in duration, those of us that are close to the end of our journey sense time is at another level. And only nostalgia can mark certain points of our journey. Now, notice I wrote that from a romantic perspective. And, what I stated included a lot of "feelings." Yet, we are told time doesn't exist yet we know for a fact time can be measured and noted by a human being throughout his or her life. That in itself proves both extremes exist regardless and at the same time...lol. However, we eventually realize the past and future are irrelevant and only the present moment truly exists. And, here we are to witness current discoveries that may alter time. Once you consider the constant reminders that life is definite, and this never changed throughout "time" of human existence... that we know of,...lol, and now you are introduced to time travel?! Wow!!! That changes everything! Especially if such technology is granted to each of us! And, now, life is indefinite? Right or wrong, this is only a means to have Godly powers! Now, consider the possibilities that may be utilized! Especially, with the advancements in DNA modification! CRISPR selections can and will extend human life spans as we know it! Especially, if time travel allows such abilities early in our origin! That may appear exciting, yet, maybe our downturn. It would change everything concerning the Tower of Babalon! And, that would confront the powers of "the gods" or God! Would that cause his or their wrath?! Now, assume mankind with life-extending capabilities existed at that moment. And our sexual desires as it is, the world population would have met the earth's ability to create abundance and to complicate our needs long ago! Kinda scary to me! But then, it's not like our situation is any better. We are at the point of assured extinction. That in itself is an issue people avoid yet it is the six-ton elephant sitting on the sofa. Personally, I think it is inevitable. Hopefully, I'm wrong. But, I'd bet on it in the great casino in the sky. Hell, who knows? Maybe we are the result of our future human race that came into our history to fix and alter our existence, and to extend our chances to survive long enough for them to exist?! "They" are exploring that possibility as I speak. Of course, the literalists of the Christian Canon scoff at such notions, but again, who knows? Life itself suggests such notions are possible. And, only time offers changes in human development. But again, the notion of time travel is too mind-blowing to comprehend! In fact, the possibilities of such abilities may and will cause detrimental consequences. For instance, to go back in time to extreme periods may require the traveler to be inoculated against viruses and organisms known at that time. Not only can that cause the traveler's death, but the human race once he is brought back. But again, maybe the use of CRISPR can cause resistance. Otherwise, time travel could be the end of human life. Or, maybe the "new" diseases are the result of time travel...lol. I'm sorry, but I'm musing at the whole concept. If anyone cares to share their notions on this possibility will be appreciated by me. After all, such thinking is a product of human creativity...lol. And, can be the cannon fire of future fiction...lol. Jus musin...

I'm only 27 seconds in but here's my two cents worth. Wasn't there a time travel experiment years ago, where they got two identical (incredibly accurate) clocks, left one stationary and put the other on a plane around the world. When the two Clocks were brought back together they were at fractionally different times. something to do with movement and speed. proving time travel in One Direction possible if you could go fast enough. Edit: one last thought, if anybody from the future with a time machine sees this message, don't forget to go back and erase the menace who invented tiktok. (Surely that's why you invented the time machine in the first place.) ....dammit, it's still here ! (Still, it was worth a shot.)

time is not linear so even if you went back in time it would be a different time line that exists in that moment, it wouldn't affect the timeline(which is more of a dimension and not a line since a line is linear and that is not how it works, I use the word timeline to describe what it truly is) you came from and possibly you could never "catch up" back to your specific time/dimension

The problem is you'd have to travel through space aswell, if that wasn't enough you'd also guess your destination correctly so you don't arrive/spawn in a planet/sun/black Hole. Here comes the solution. Trust me I watched enough movies/shows/Games to know what I'm talking about. We would have to build a platform for future time travelers to safely arrive and land. A platform that is ideally not moving in space and always stays at the same spot. If we manage that I'm sure we will see time travelers immediately.

This is my own theory and belief. Everything that has happened in the past, is happening now or will happen in the future, has already happened. In other words, time is already set in time. Everything that has happened in the past, present and future has already happened and is set in stone. It is actually we who travel through time. We can travel through a neutral higher conscience state spiritually to the future or past. This process falls into the Conscious Energy State. We cannot change the past without creating a new timeline. If this happened, then we could not return to the present time in our present timeline because of the effects of changing or creating a new event which will effect the future. A problem with this is that you, yourself, also could not return to the same timeline that you left. This just makes sense. Timelines are unlimited in number. The late Edgar Cayce is a prime example of this scenario. He could go into a self enhanced spiritual conscience state and make factual predictions of future events in detail as the future winners of Horse races which he quickly stopped when he found out his ability was being abused. Think about it with an open mind and see what you think about it.

DAMN I LOVE THIS SUBJECT!!!!!!!

I believe using Lazar's manufacture a Taurus might work, but I think Gravity is the key...if he ran his device on the Zero grav plane I think he could archive his goal....if not...try frickin sharks with lazars on there heads next time

I've seen the movie The Butterfly Effect 🦋 This isn't a good idea. 😐 Also BTTF 2, Biff becomes rich and distroys everything. Can you imagine walking up to up to the Captian of the Titanic and trying to tell him I'm a time traveller and this ship will sink. I doubt that would go down well. 🤓

Funny how people from 2021 talking about time travel. We practically use it like a tenchometer on a daily basis in 2350

Hmmm When my crew and I departed Tokyo on Monday morning, a mere 7 hours later we arrived Anchorage on Sunday night, a day before we actually left. That's MY time travel.....

I think the formula for timetravel,is to create an electricfield that leads to any given time in history and the future. I also think there are portals that leads to any given place in the universe,and to any timeperiod. What remains is how to controle these phenomens,and then tourism might start ?

To be fair, only by thinking in terms of what we know, things seem impossible. Archimedes spent many hours wondering how gold was stolen from the palace, until he figured out how buoyancy worked. There are always higher laws that govern the lower laws. Basic mathematics is governed by physics, if something in physics were to change, the lower laws (mathematics) would change with it. However, if something on the lower laws were to change, physics would not. That is what the field of quantum physics is for, it is the search of what governs the law of physics. It would be possible in those higher laws to go back in time before a time machine was built, and still get back the same way. Once we figure out teleportation, we will be able to make advances in time travel. Maybe there needs to be more true mirrors and convex lenses to speed up the lasers and increase mass while reducing the size of it.

I have successfully built a time machine, currently it can only travel forward in time, and only at the speed of normal time, but I'm working on it. It was tested successfully at 4 pm on December 2020. I entered the chamber at 3:50, set the controls to jump ahead to 4 pm. Ten minutes later I exited the chamber and it was indeed 4 pm! A full ten minutes had passed. My next objective is to jump forward in time by a substantial amount. My current goal test date is March 14th 2021 where at 2:am CST I plan on attempting to travel forward in time 1 full hour. If successful my next goal would be attempting to travel back in time. It may take time to recalibrate but I may be ready for a test around Nov 2021.

I always wish to time travel, atleast like shown in "about time " movie. I hope my wish come true some day.

Time travel back to the good old days before COVID would be nice!

Like particles have mass like anything else. That means it can be affected by magnetism and resonance. You need a cylindrical magnetic. Cone spinning in the opposite direction of a cylindrical magnetic cone inside of it and opposite direction at the speed of light. Then you can open a wormhole and go as fast as you want.

Thoughts can travel through time,,plant your positive seeds of thoughts where they might do good

I tried time traveling by breathing on a Muffler- All I Felt was Exhausted...

The key to time travel ist in light. if we travel at the speed of light it would still take us 2.5 million years to get to the Andromeda/M-31 galaxy. The key to time travel is in what Einstein called "Spooky action at a distance" or Quantum Entanglement

There is so much talk about Physics and the physical possibility to progress or regress through time. Surely the dream is not necessarily a desire to physically move through time. If we take another debate - such as what happens to our consciousness when we die - and involve that with time travel. Is there a realistic theory that could move our consciousness backwards and forwards through time. Surely for us to have experienced time travel we need a "memory" of it happening. This is on a conscious level and not a physical one. Something in our brain telling us that it happened and making it real.

I have a real time machain it's my 68 camaro every time I drive it ,it takes me back to my youth the sounds the smell it's perfect

being a professor is enough to make any father proud...

I always had the thought that no time traveler could go beyond the time the machine was made. Hence any form of trying to change the past would still be within the timeline of said machine, so Past and Future would essentially be always on the same Line, No matter what they try to change would have already be taking place in the present as to when the Machine exist. So they would not really be changing anything, For eg. Someone is killed during the timeline of the machine and they want to change it, the fact it was never prevented in the present moment means when the use the machine instances will happen that will prevent them from saving that person which would explain why the said person was killed in the first place.

Time is a logical procedure used to identify the stages or length of the process of interest. The person or AI compares the properties of this process with the properties of the standard one. To say I want to travel in time, like say I want to travel in measurement. :)
