Neil deGrasse Tyson - Can We Go Back in Time Using a SpaceTime Machine?
Subscribe to Science Time: / sciencetime24
Astrophysicist Neil deGrasse Tyson explains the details behind backwards time travel. When we were kids we wondered whether we can travel into the future or go back in time using some sort of time machine.
Neil deGrasse Tyson also explains how and why we know we can travel into the future. Special and general relativity, suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel not only into the future but also into the past.
Perhaps the best way to go back in time is to make use of traversable wormholes. Neil Tyson explains all the intricacies of going backwards in time using a wormhole
Another exciting approach for backwards time travel, involves a dense spinning cylinder usually referred to as a Tipler cylinder.

Well ya gotta remember that what we think of as the past present and future actually ALL coexist simultaneously. We only conceive those notions because of the speed of light. So if you were to “go backwards in time” you wouldn’t be aware of it - you’d literally be reliving the “past” all over again - making the exact same choices, meeting the exact same people etc. This is why you couldn’t go back and change things. This is also why it’s impossible to travel back to a time before you were born.

@tmxband

There is a thing that is possible in theory, it’s to observe the past. With a theoretical warp drive the theoretical upper limit of speed is ridiculously high. If you have a huge planet size telescope (gravitational lens) you have the chance to look back in time. Just as we see only the past through our lenses, if we leave Earth with extreme speed and look back on it with high enough mqgnification we could see our past. With the speed and distance you can calculate how far you want to look back. So theoretically we could have a look on dinosaurs or whatever. Fun thing to think about it.

@@deenell9039you still wouldn’t be able to see the dinosaurs. There’s no way to see back in time in that aspect. In theory if you traveled an arbitrary number of light years away from earth and looked back through a telescope you’d still be seeing earth the day you left because you’re just magnifying the image to be visible. You aren’t seeing images like an iPhone sends, you’re seeing a physical surface, light particles don’t carry the image. There’s no way to travel back to past events. Back in “time” in theory, yes. But not to past events.

@somersetcace1 Год назад
I think the paradox would be dealt with, IF each movement back in space-time then created a whole new branch of space-time at that point. So, you go back to 1900 and from that point there becomes now two divergent space-time branches. The original branch then remains unchanged because your self is no longer on that branch after whatever point you leave. Each time you move forward or backwards a new branch is created, meaning you keep moving `forward` in a relative sense through each new branch you create, regardless of where it is on the timeline. In that case, you could kill your parents before they had you and avoid a paradox, because `you` weren't born on the space-time branch you killed them on and *that* space-time branch still exists unchanged to the point you left it. There's not a shred of scientific evidence to support that idea though, so it's kind of just mental fluff. What would it take to overcome that paradox?

Lets get one thing straight. If you could travel faster than light you would indeed be traveling backward in time. However it is IMPOSSIBLE to also remain in the same place. In other words you would not be able to travel through time alone. Which means you will always travel a DISTANCE in order to go backward. If you tried to return to your starting position you would in fact have to travel through the Bulk( If it is a thing anyway). The only way that this works is if you travel to a distant point faster than light,( So you travel back in time) then you would have to turn around and travel back to you starting point at sub-light speeds taking the length of time equal to the distance traveled. The wormhole is only possible for that brief period that you travel at FTL speeds. You would end up at your destination near instantly. At least this is the way I think about it. It could also be the case that the only way to travel through time is to use an engine that would instantly launch you through a wormhole to the same point in space but backward in time, however this would require all the energy of the universe, I suppose it might be possible to only create a local distortion but I doubt it. Locally it would create a new separate timeline, if in fact you could build up enough energy sitting still (relatively speaking) to instantly launch into the past. It would have to be a instant transition otherwise you would end up as paste on the bulkhead. I still think my first thought is more accurate though

It still wouldn’t allow you to go to a period of “time” of past events. “Time” is just a certain amount of units we measure daylight in dictated by the earths orbit around sun. Other planets have different “time” speeds. It’s truly a misconception when people say you can time travel. If you traveled 5 light years away and then traveled back to your starting point at regular speed, you’d be the exact same age the day you returned. A 40 year old man is still a 40 year old man whether he’s traveling super fast or not and he is still dead after 5 light years the same as the person on earth would be dead. Deterioration and aging is still a thing even if “time” travel is possible. Which it isn’t in the idea going to different places in history.

The Paradox that no one talks about in travel across temporal regions is that the organization of matter is typified by the expansion of space and time.

When I first began to learn programming I wrote a python script to calculate time dilation when traveling to and from alpha centauri and one of the things I observed was when moving at 99% the speed of light any small increments to speed can yield massive differences in the result. Now this was years ago but I somewhat recall the result was like 125K years into the future moving at 99% but as soon as I start adding that .9's I was easily able to produce leaps in the millions.

But I’m ur world everything is the same.

There are possibly alternate timelines in the past depending on other peoples decision like the grandfather paradox If grandpa dies as a kid before meeting grandma for the first time, then you won’t be born as he helped your grandma give birth to mom/dad then, your mom gave birth to you He’s like he’s part of your body because you need his genes in order for you to exist in this world But if he dies so young, then your grandma would find a different husband and start a family that isn’t you or your relatives

Well ya gotta remember that what we think of as the past present and future actually ALL coexist simultaneously. We only conceive those notions because of the speed of light. So if you were to “go backwards in time” you wouldn’t be aware of it - you’d literally be reliving the “past” all over again - making the exact same choices, meeting the exact same people etc. This is why you couldn’t go back and change things. This is also why you can’t go back to a time before you were born.

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city complain about the same time paradox unless it was effected by it. Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're randomly given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ????

Regarding the grandfather paradox: what if all of time -- past and future -- has already been written and set in stone. I.e. we experience the present moment, but our future is already predetermined. That means, if someone were to go back in time and prevent their own birth, they simply would not exist and so that possibility is wiped out in the first place -- meaning NOBODY has the ability to even attempt that in our universe. However, if someone went back in time and did not affect anything with their birth, then this is allowable and so this person may exist. Basically, anyone that decides to affect their own birth via backwards time travel must fail, or else we wouldn't know about them as they would not exist in our universe at all. There may be people who want to meet their parents, but they would fail to prevent their own birth. It's the only logical way that this paradox can be explained whilst permitting backwards timetravel. In summary, the life you are experiencing right now is only possible because you and nobody else in humanity went back in time to do anything that prevented you or them from being alive.

My theory is time travel into the past is possible and even if we changed something that happened in the past there is a way that things could work out without causing any paradoxes. For example, let's take the famous grandfather paradox. Let's assume that someone has traveled back in time and killed his grandfather. In that scenario, his actions won't be affected to his timeline or future. It will only make a branch alternative timeline, which is connected to the main timeline, where his grandfather is dead. In that way they all make sense.

You would run into your past self so you would have to kill your old self, and replace them. Then brings in the time paradox question, does killing yourself after traveling to the past change the fact that you already traveled to the past?

​@@papasmurf205 no that's BS nothing will happen where do people get that theory from. but if you do end up killing yourself from the past then you from the past will not exist you will prevent yourself in the future in that timeline

Every time you sleep, your mind leaves the present, then travels in the future but your body advances through the normal flow of time. At wake moment, your body catches up with your mind. Time travel is not yet a scientific reality but it is a spiritual one. 🤭

*What about time viewing, or sending information forward and backward in time? As far as the paradox goes for physical time travel, I remember something about that in the movies DeJa Vu and Terminator Genisys. If you physically travelled back in time, and altered your own history, you would remain intact. As long as you remain in that new timeline. Right now I'm thinking about the multiverse theory, for some reason... Would changing the past create another universe, taking a different historical course?.. But I want a focus on the first questions... Can we just VIEW the past or future? And, can we just send INFORMATION forward and backward in time?.. Maybe this would be connected with faster than light communication?*

You should read conversations with Nostradamus by Dolores Cannon! In this book she explains how she did this. And in viewing the past, people that can do remote viewing are able to do this (supposedly) the CIA has been investigating this for decades and work with many remote viewers (again, supposedly) you should look into it :)

Maybe if the Bitcoin you bought wasn’t a total grift and they didn’t refuse to pay out like so many of them did.

Imagine you use it to time travel and the time you travel to has a tree or some other obstacle in the exact spot the time machine should've been. What would happen then? Would the matter instantly repel or would the time machine be atomically (or in some other way) fused to the tree or obstacle?

If there was something that forced you to land outside your past light cone when you travel to the past, then the Grandfather Paradox is solved, too. Isn't it?

You want to be careful going through wormholes. John Crichton went through one and his life was turned upside down. Two species that were warring with each other both chased him everywhere to get his wormhole knowledge. On the positive side of things, he hooked up with a really hot alien girl that sounded very similar to an Australian.
