Does The Future Exist? 

I think what this leads to is "mindfulness." Existing in the moment. Thoughts are about the past or future. It has a spiritual tone to it (Eckhart Tolle). But, there are basic principles involved (don't think; exist in the moment. The past & future are constructs. Like a snail remembering something it picked up from its elevated "eyes." It's just a matter of degrees. All that is real is *now*.). That kind of stuff naval-gazing to me in the past. But, it really is like the inverse of waht you said. Taking spirituality (existence) to a border of physics. There's only one moment (now) in the universe. We're the only things stitching past and future into now (snails too, to some lessor extent). What turned me onto this way of thinking was a RU-vid channel mindfulPeace. They had these two videos: "Guided Mindfulness Meditation on the Present Moment. Be Here Now." The other is gone now. They've created a slew of new videos. But, that one (and the one gone now) were very basic. About recognizing your own thoughts as they arise. Differentiating between being in the now vs self-talk, rumination.

Exactly! Well said Feroze

That's why studying science is amazing, studing how the universe work is looking deep inside of us because we are all part of this thing that we don't know what it is, but we know that it's happening right now but we are not different from chemical reaction or physic forces, we are made of matter and energy the two things that make this universe we are indeed the universe itself, the line that separe our complexity of our body and the rest, is just immaginary.

Yeah I really appreciate it.

I was born in the 80s in Central America, no electricity, no internet. Im addicted to learn more about the nature of reality and because i dont have the mental capacity neither the education about these kind of stuff i appreaciate these youtubers, Arvin, Nick, Alessandro, Fermilab and PBS. Unfortunetely (most) people born after the year 2000 are more concerned about TikTok, hip hop and pornography, maybe when you grow up with scarcity wondering about God and the universe is a good thing to help you appreaciate the answers your are given so easily driven by your curiosity.

Pessimistic instead in review 😄😄😄😄😄

dx means a really really small change in x sometimes written as delta(x)

@@its_robbietime1333 I am aware , I knew the definition but this video really put it into perspective and gave me the best visual I have ever seen

@@Dina-he1uc oh okay thats greatto hear

You just need to learn things one after another, in order. For sure that info is written somewhere in the beginning.

How!? I learned in this in my literal first lesson in high school calculus

I also scrolled up after reading your comment but then i scrolled down to like such a genuine comment for the praise of such an interesting channel and person.

It would be a cos not to like your comment.

Timothy Haldane nice one😂😂😂

Yes ! And the punishment is that you will not get sec

If you didn't close, then why did you reload?

Probably the greatest video you have done.

I'm pretty sure I'll hit the mark this summer... but, if we're being honest, the active and (mostly) positive comment section I get on my videos is more important to me than a sub count. The sub count only matters to the YT algorithm and for gauging how much the channel is worth to sponsors. Those are less important than the connection I make with viewers.

Thanks for the reply. It made my day 👍

There is nothing similar I have ever seen here in Europe - congratulations to you and your team - simply excellent - subscibers +1 ;-)

And that's what makes you a true scientist

And I chime in on the gold mine. Aligning all his videos with my knowledge has become a fun and rewarding past time

Yep. That's exactly why he's there.

What is the name of the book?

Peter Kokarchev The one in the description to this video, Advanced theoretical physics

Exactly

Thanks for the support! And yeah... sometimes people have experiences (or disorders) that make certain choices _much_ more difficult than they are for others, but there's always a choice.

Thanks!

tsuchan1 Oh but even that would be just wishful thinking.

“Fake it till you make it”. The mantra works.

Yoso If the _intention_ is genuine, then it won’t be wishful thinking.

I'm glad you enjoy them :-) I've been doing really tough topics this year. I'll be taking a break from that over the next few months to cover electricity.

You're welcome. Glad you like them :-)

I am watching a movie I receive notification, I am jumping right here.

Thanks! 😊

I'll be at VidCon in a few weeks. That should help.

You went to college without already understanding calculus? Could you read yet? It makes me angry that people like you exist. Detritus clogging up the system and ultimately stealing the career opportunities from those with actual ability.

@Hugoj Sim racing dont go anywhere

He already over doubled that amount of subs

@@PinkeySuavo the silver play button is now in his past light cone.

In the when?

@@beaconblaster33 He should have it by now. Lol That was 2 years ago.

Sorry, no more...

@@darkages9507 yes... No more

Your two years in the future is now in my past

you just saw the video and wrote that comment in different 'nows' which are really the same now.

You don't seem to have relaxed your concept of "up" and "down." The screen doesn't determine that. The axes do. If you can rotate the axes so that the space axis is between the observers, then you've made them switch... even if they don't move on the screen.

Q: Why does the light cone of yellow face not move with the transformation? A: *Because the speed of light is constant for all observers, and the center of the cone is defaultly located at the cause event.* Q: How can your head become "lower" (or "before") than the yellow face by just changing the perspective? A: *When two events are separated by such a long distance that light cannot travel between them in the time it takes for them to occur, they are considered non-causally connected. This means that different observers may disagree on the order in which the events occurred since there is no causal relationship between them. The reason for this is that nothing can travel faster than light, so the events cannot influence each other.* Q: Can you explain what type of transformation would bring the two events shown at 03:50 to reverse order? A : *the type of transformation for (t,x) to (t',x') is called the Lorentz transformation*

​@@Mysoi123take my like

I just made it part of my present by interacting with it.

What about plank time? Could that be considered the present? As it might be the smallest chunk of time? Could that be the "infinitesimal" value that we are adding?

I just influenced your future somehow by writing a comment that you've read

If you think that got past me, you're mistaken.

NUKE Maybe. The problem is that we don't know if plank units actually are the smallest ones possible. We don't even know if there ARE smallest units. Its entirely possible, even plausible (at least as far as I know) that both time and space are infinitely divisible. No one has figured it out yet though. There's probably a Nobel prize in science and/mathematics for whoever figures it out either way.

Thank you so much for supporting! Your questions always keep me on my toes, which is a good thing.

He preemptively answers the questions that most people have

No this is Patrick Exactly.

He doesn't do this all by himself! He has an army of clones helping him.

@@XEinstein lol. I love his clone stwick

If I can get this channel to a place where I can hire help, I might be able to make more.

Xcalator35 c fuck off. Idiots guide to science by and idiot!

@@garyaubin8016 who are you to judge anyone

@Xcalculator: Ain't that the truth!

I note that the QEE surprised those who believe that the future is not causally linked to the present and the past (the ones who believe in free will) while determinists saw nothing strange about it.

It suggest scientists like fairy tales, time machines, warm holes, warp drives, just like little kids. Time is reversible, but there is no point to talk about cause and effect if they were already pre-determined, they are just now.

+Chike, what? Scientists like fairy tales? What it shows is that there is no predetermined time, a quantum action in the future can go back and rewrite the past circumstances. Time is pliable, and rewritable. You can't destroy information, but you can cause the information to have never existed in the first place. Secondarily, warm holes and warp drives are completely within the limits of reality, and would in fact act like a time machine if we could get the negative energy necessary to keep them stable. Going faster than light would in fact take you backwards into time (from your perspective). Now, FTL travel might not be possible, but we haven't conclusively proven that just yet. Quantum entanglement shows us that it is possible for certain things (entangled particle pair information) to travel at effectively infinite speed, we probably can't transmit anything useful through it, but it does demonstrate that the quantum world doesn't necessarily give a crap about the time dimension.

Why do you say re-write, have you seen it change? Like I said time is reversible, the *sequence* of events does not change. How do warm hole settle with the sequence of events? Events travel at the speed of light. Say you have seen an event on earth and went through a worm hole someplace far, you will now see it again *buzz* ! not possible, you can see an event at a specific time and location only and no other time but that time, you can see it at the same time and location how many times u wish, but only at a certain now and where. And what about preservation laws? No, I know the eraser experiment, and the photons on screen look the same either way, what it show is you can predict where a certain photon will hit, no better than you do with 2 slits anyway.

+Chike, "Re-write", because based on where the particle is detected, it's past could only have had a single timeline out of 2 possible states, wave or particle. The final state's measurement forces the initial state (future re-writes the past). How did you determine that wormhole travel is impossible other than saying that it might cause an apparent paradox? But the paradox doesn't exist when you consider just your timeline. Even if a time traveler went and changed the past, you wouldn't notice, since your brain is in its current configuration and can only witness what it records. The fact that you're limited to your time slice doesn't mean that the rest of the universe is. Preservation laws can be broken, time symmetry was shown to be broken not too long ago in a special particle. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yArprk0q9eE.html Based on your last paragraph, I believe you may not understand the delayed choice quantum eraser experiment. It's not about where a photon hits, it's about whether an object is it's in a wave or particle state and that the final measured result is what forces it into the particle or wave state. The future measurement affects the particle's past solution, here: How the Quantum Eraser Rewrites the Past: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8ORLN_KwAgs.html

Like I have said, I know the experiment, watch it again closely, there are never 2 lines you would have expect if you try to detect which slit they went through, you simply cant say anything about the photons when you examine them against a and b detectors, but you observe interference pattern with C and D detectors, and you still do not know which slit which photon went through. All you can say is that photons detected at C will create different pattern than those detected by D, any other interpretation is bogus, you have no idea of why this happen not it help you to understand it. Either you accept information travel to be the speed limit that we would never be able to reach or not, you must make up your mind, if it is you cannot see the same event twice, if it does not, we can argue. There are no paradoxes in the universe, nor any conservation law is broken, not in my theory. Make it rule #7, if it creates a paradox it is false. Tell me, what is this "wall" between the slits for a gravitational wave? Would you get the same pattern if it was made of neutrons with no electrons circling around them interacting with the gravitational wave, caused by the particle, no space between them (or much less space between them) to allo the wave to continu? Don't take what science tell you as granted, ask tough questions, and keep asking until there the answer is satisfying (one that does not raise another question or more) Quantum theory rejects relativity, so it bring back a question that had already been answered. Still it use it to make other predictions (Hawking radiation/Unruh effect) that have yet to be proven right.

Lol

i just noticed that if you had a time machine you could never go to the future, because when you go to the future it then becomes the present and your origin time is the past. (kanshpyracie)

Amber Flame beautiful

why did i just say kanshpyracie?

OH I MEANT CONSPIRACY

Thanks!

Well Seems like you over shoot that by 6 months and 30 days ^^ at least according to my point of spacetime reference.

@@MouseGoat , He must be in some short of loop already.. some paradox you know?

@@SNK1995 I dont think space-time alows for paradoxes, so no i must say i dont really understand what you getting at here. :O He said he would be here yesterday, but now its 10 months ago, now normally you would say that is because i have moved 10 months forward in time, from the point of him writing that comment. but from my spacetime reference, its him moving backwards in time, noting paradoxical in that.

@@MouseGoat, aha... Now i got it, thanks for the explanation. 😁

When i read "see you all yesterday" in his comment i suddenly thought of time travel, and then came the thought of paradox. 😂

You can go to a place where time ticks slower or faster or speed yourself up significantly to change your time but it will always be your now.
