Does The Future Exist?

The concept of a space-time seems to suggest both the past and the future already exist and that the freedom of choice is an illusion. However, a deeper look into cause and effect, locality, light cones, and infinitesimals still leaves an opening for freewill.

I know Nick isn't intentionally motivating us, but I feel very relativistically optimistic at the end.

[@miti3369]

Pessimistic instead in review 😄😄😄😄😄

[@safiya4339]

This is profound, taking physics into its border zone with spirituality. Younger viewers than me (ie virtually all of you) will not be able to appreciate how lucky you are to live in an age where you can access this so easily. People like Nick may be the true heroes of our age.

[@markfuller]

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 KZbin 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.

[@SB-lc2vd]

Exactly! Well said Feroze

[@99fulgur]

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.

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.

[@evrimagaci]

Can you explain what type of transformation would bring the two events shown at 03:50 to reverse order? I can't think of a transformation of axes/tilt to reverse the relative positions of those two objects (your head and yellow face). How can your head become "lower" (or "before") than the yellow face by just changing the perspective? Why does the light cone of yellow face not move with the transformation?

[@ScienceAsylum]

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.

[@Mysoi123]

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*

Hello Nick! I remember that I read a very interesting and well-written book on physics, which helped me to understand more about tensors and quantum mechanics, when I was studying at university a few years ago. I accidentally discovered your channel surfing the youtube a couple of months ago. By now I think I have watched all of your videos, and I really love them!). What a surprise was for me when I realized, that the book was actually written by you). I couldn^t finish it all at that time, but I^m definitely gonna buy it now. I teach maths and physics to high school students myself, and your videos improved my understanding and answered some of my questions about gravity and relativity. So THANK YOU very much, keep up the good work and I wish you good luck in your future projects and in your life!!!

You should do a video about the Delayed Choice Quantum Eraser. It suggests that cause and effect might sometimes work backwards and the past can be rewritten based on future events.

[@nadavdanieli]

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.

[@eugenes9751]

+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.

[@nadavdanieli]

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.

[@eugenes9751]

+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. kzbin.info/www/bejne/r3LVoaWhZdZsm6c 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: kzbin.info/www/bejne/boC1fYGVgNx0ndU

[@nadavdanieli]

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.

I'm popping out of my cone for a second.. see you all yesterday..

[@MouseGoat]

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?

[@MouseGoat]

@@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. 😁

[@SNK1995]

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

I had watched this video in my past and knew I will be watching it again in my future, I watched it again today and it was my 'present'. Nice video Mr. Lucid.
