Is all that exists just whatever exists right now? Is the past erased and the future a void yet to be filled? Well, the answer lies in between the past and the future - in the elusive, ever-moving eye-blink that we call the present.

  • The Past exists in the Present; the light from a distant Star is from our Past, not from our Present. The Star actually exists in the Future, possibly millions of years older than it looks to us; and it will have to wait millions of years in the Future to see the light of our day. The Past, the Present and the Future exist at the same Space-Time...

  • Does this explain why if a traveler were to travel at near speed of light around a supermassive black hole for about 10 years they're relative time would put them well into the future when they come back home? Because their light cone had them aligned with observer's light cone in the far future?

  • Time is a human invention. Just our way of using one natural process, say the oscillations of Cesium atoms, to measure another natural process, say the orbit of the moon around the Earth. We might posit a hypothetical 'instant' where everything, everywhere is at a particular point in their progression through entropy. It's just that it's fiendishly difficult to model because of the speed of light and the expansion of the universe.

  • One big problem I have with all time existing and we just experience individual slices, moving from one 'frame' to the next, is that implies some minimum 'planck time'.. Or in other words, that the universe has an FPS, or "frame time" If planck time exists, are we really saying the photon doesn't move between those two planck points, it teleports?- Meaning *_if_* we could ever see a shorter time scale, between departure and arrival, the photon doesn't exist? And when does it teleport?.. At the end of the current planck time, or the beginning of the next--the tick, or the tock, if you will.

Also, there's the dark forest theory by Cixin Liu which I kind of like because it manages to make humanity less special whereas the other solutions put us on a weird throne of good fortune.

  • Delay between an action and that actions causality wave reaching me is just causal latency. Causal latency is not evidence for the existence of a separate past/present/future any more than audio latency from the speed of sound is. You can do tricks with sound that play with the order a sound is heard between multiple objects moving at different speeds relative to each other that mimic causality tricks where you can't agree the order actions occur in. In sound's case , the existence of a side-channel (light) that is a much faster conveyor of information makes it clear which "actually" happen first. With light this isn't the case, there is no faster channel, the speed of light (time) is all we have at the moment, but that doesn't mean that causal delays are implying weirdness with time or implying the existence of a past or future any more than our existence implies the universe is trying to create a way to observe itself. Both are logical fallacies from taking thought experiments out of context and way beyond left field.

  • To say that the past is "erased" to describe "presentism" is kind really of implying an "eternalist background" POV where there's really this eternal "plane" that "erases" somehow the past, or though with the present "travels," with a lot of empty "time space" behind and ahead, versus just the "now"/change only existing, without this kind of "substrate" inferred from our "mapping" of events. Past was never "erased" literally like in "Langoliers," or as in a tape that's erased just after it goes past the VCR head. You can't go back to "empty" space with nothing or ahead to a future where "nothing" reached yet. To "go back in time" would literally imply in moving everything back to the states they were before, and it wouldn't even be 100% literal unless you'd really cheat on entropy and whatnot, somehow.

  • These notions of time being an "illusion" of a determined/static extant set of events seem to implicitly assume that there's some sort of immaterial soul that "flows" through the "block/tape universe" having this magical immaterial illusion. Or who watches a projection of the "illusion" movie, again, implying a real, in a non-illusory time, and a bunch of other weird stuff. Not to mention the probably unfalsifiable "present"/eternal existence of all past and future from determinism alone. But I think that since causation as a chain of events kind of ceases to be a thing in a way, it's not incoherent to imagine it. You're free to imagine all kinds of things that make no sense whatsoever out of the "illusory" chain of temporal causation, maybe we just watch the movie-illusion recorded by a god movie-maker or something, there's no point in trying to even prove it as it would be way beyond anything we could reach with scientific instruments or even reasoning.

  • Distorted logic can prove anything is possible, its just that the results are distorted. Example, what has the speed of light have to do with the present, wherever anything is happening in the universe that is what is happening now, the fact that we dont see it for maybe millions of years doesn't mean it happened at a different time.

  • Can anyone see the Present objects? If you can not see the Present objects, how can you see the Future objects? Everything we are seeing is the Past thing. Every light particle that hit our eyes came from somewhere in the Past (it could be super short Past, but it was the Past). Sometimes Physicians and Scientists are wrong, because they stick themselves with the light particle things. They should study about the Mind too, the mind is something and it is real. The mind sees everything ( not the cell of our body parts sees thing). The mind can see everything in the Past, Present, Future. The mind can see without rely on any light particles.

  • The fact it would not break any laws of physics to go aboard a space ship, fly it towards a black hole so as to sling shot around it and reach the speed of light and survive.....prove dimensions in time have an end.....and we know from the expansion of the u universe time had a beginning....and this would certainly prove we have the knowledge to travel into the future already......the fact we do not yet know how to travel into the past yet does not mean it is impossible it just means we do not yet know how..... So if we could travel into the future a week or two and then return would that conclude all moments in time co-exist..... But remeber the space ship traveling up to the speed of light and an infinite of earth time passing......indicating our current time dimension ending...without time to separate moments and events, would not all that ever was exist simultaneously ?

  • That light cone bit doesn't make sense. What you see coming from those stars is not your future, it is their past. Someone traveling to a star would see the stars history before you but that does not put them in your future. They are not where they are when you see their light. You're seeing them where they once were. Seems like everyone talking about relativity like to swap out objective reality with subjective reality. The twin paradox for an example even without acceleration is not a paradox. Despite your inability to know which one is traveling near the speed of light by observation. Only one of two is actually exerting the energy necessary to travel at that speed. The one exerting the energy is the one traveling near light speed. Thus there is no paradox who will experience the time dilation.

  • Time doesn't exist ....... it is an arbitrary relative measurement of existence created by man. Past, Present, Future are NOT Things. The universe is INFINITE so the "THINGS" in the universe have always existed, exist now, and will always exist. The only question is if they will exist in the state they are in! The past exists and is set, the future is not set. Universal Relative Perceptional Time is universal throughout the infinite universe, but you relatively experience it. Time is not a dimension it is a marker to calculate STATIC (snapshot) physics. Which all other is DYNAMIC (perpetual) physics. He is not talking actual physics he is talking "perceptual" (by word play).

  • How about the idea that solypsism and materialsim are mutually-compatible semantics each simply describing that this block universe exists with you as part of it, and is the only universe, period, which always is, exactly and only, "this." -- Which includes everything. -- Absent any observer, it is just all quanta, and if some of that quanta should be an observer, the nature of that observer determines how one perceives the rest of the quanta, and what of it one can. But the totality of quanta always is, regardless of any observer w/in itself or not. -- The block always is, and behaves in all possible ways simultaneously. An observer perceives select aspects only, but is always one part of its whole. -- Maybe.

  • Huh...just because the light of something occurring hasn't reached us yet doesn't mean it didn't happen in the "now". The very fact that it takes a determinate amount of time to reach us, for us to observe it means we can trace it back to when it actually occurred at that point of time which was the "now" for everyone in the universe at that point in time. Why do you guys (Physicists) base reality strictly on observation? It sounds stupid, but think about it. I can't observe what 6 billion people are doing across the world but we know they're doing it whether their "light" reaches us instantaneously or not. There are Aliens out there DOING THINGS RIGHT NOW whether it takes a millions years for their stars light to get to us or a billions years. If they travel to a star that explodes right now, and get there as it explodes, but we don't see it until a hundreds years from now, it doesn't mean it didn't happen. And it's not relative to us or them, it's relative to things occurring. Sure it might be compressed more for tgrm and stretched out for us, but there's still an overall picture if everything occurring in space/time "outside the box" like your picture showed. Such a peculiar notion of existence. And then you just allow these quantum hocus pocus mystics to run free with their snake oil bullshit of "The universe only exists when we observe it and will it to be". We haven't been around for 99.99% of the time the Universe existed, yet we know it did. No one was there to "OBSERVE" the universe into existence. And that's when you allow these mystics to bring Goooood into the equation.

  • Could someone fact check this for me? My understanding is that the present is a static moment across the universe, however distant objects and events only appear in our perception of the present once their light waves reach Earth for us to observe. This means all events can only be observed in the future. Assuming that the speed of light is constant and space expansion could potentially exceed the speed of light, does this mean that there are events that have happened in our perception of the past that we will never be able to observe and therefore never determine as having occurred? This would also apply to present and future events given that the space expansion between the location of said event and Earth exceeds the speed of light. I may have explained the notion of the observable universe, but I would appreciate some input on this.

  • We could also approach an instant in time as being infinite in duration. Morimoto et. al. "Superluminal Motion-Assisted 4-Dimensional Light-in-Flight Imaging" have shown superluminal motion can be captured but how far can we slice up time. An infinite amount of information flows through a hypothetical imaging system as dt approaches zero even though no work exists at those scales with respect to its reference frame. Therefore how do we really construct a ruler for time.

  • It seems more to me that you are expressing the perception of time rather then the reality of time. Reality itself is an outward spiral with some fixed points, and each of us on our own individual plane of existence (and time), and the civilizational plane of existence (and time) are also streaking down this spiraling road, occasionally creating intersecting experiences that give us all unique perspectives. Time itself is more then likely what you perceive to be the instance of now, moving down the road of reality, creating the now from what could be, and leaving behind it a tapestry of what was.

Your time is the same .if the alien gets up and runs off in a direction and you measured each other’s time relative to the first recording , you’d be in different time by a a few hundred years. I... think lol well that’s how I interpreted time from this channel. I believe in yeh many worlds interpretation so that means there are multiple time lines and possibilities for your life there are infinite possible outcomes for your life . I think that each possible outcome is determined . A bit like a movie with multiple endings but they are determined already for you .

  • The Past and the Future are Concepts, It's Always Now. Visiting the past or future would require being able to jump to a different universe, but even the Multi-Verse is a concept. Sadly this is the only Verse we have and it's always Now. Let's say time travel is possible, you would need Infinite Energy, mainly because you would have to alter time as it were in the entire Universe, and if there were such a thing as the past or future, logic dictates that you can't just affect time in one small area of the universe, otherwise you would disrupt and create a tear in space time with unknown implications. Just a few of my thoughts on the subject. Take Care All & Stay Safe.

  • Time, is the measurement of the ever evolving progression of the all but infinite sequence, of every event that has ever occurred in this universe. The measurement of time is not relative to those events that are solely observed by the individual as stated. but it is the measurement of every event as a whole. Time as a scale is merely a human concept, but the speed by which that sequence of events occurs, as we measure it, is and always will be a constant until the very fabric of the universe ceases to exist. Regardless of who observed a particular event vs. who did not, that event still took place in this universe at a set point on that scale we call time. He says, when something happens light years away we dont see it until that light reaches us, so therefore we are observing the past at this, the present time. But we are not observing the past, we are not even observing the event in question, rather we are observing the effects caused by that event which previously occurred, as they progress along that sequence, ultimately shifting from current events to past ones, which like the original event that set those reactions into motion, will immediately cease to exist upon having occurred. For example. Say youre standing on one side of a pond skipping rocks across its surface. Floating around in the middle of this pond is a duck. Say the duck isnt close enough to see you throwing rocks and you arent close enough to see the duck while youre throwing them, but every time a rock hits the water, it sets off a chain of ripples across its surface. Those ripples spread out in radial waves working their way out from the point of impact, until eventually those ripples reach that duck. The duck sees these ripples well after the rock has come to rest and the occurrence of the rock striking the surface is no longer in existence as it is a thing of the past. You and that duck are both existing at the same time on the same scale but that duck is just now able to observe the effects of that rock having hit the waters surface. This does not change the fact that the rock was thrown at the same time in your observed sequence as it was in the ducks observed sequence. The only difference is the sequence of particular events which you saw and the sequence of events the duck saw. Those events still took place at the same point in time and they were still set into motion by the same previous action of your having thrown the rock, despite the duck not having seen the same effects that you saw. The sequence of events and the scale by which they were measured remain constant. You can never truly observe the past in the present as it is not in existence and the point in which it was in existence, was the present before it ceased to exist as it became the past. And the same holds true for the future as well. It doesnt exist because it has not yet come to pass and the point in which it does will be the present. To say we can see the future by calculating the sequence that a particular event will eventually occur is merely making an educated guess based on our personal observation of similar occurrences that happened and are now non existent. This is not seeing the future. At any point in a given sequence, an unexpected occurrence can drastically change the outcome by imposing new effects on that sequence therefore it is not the future but merely a guess the final outcome has not yet come to pass and when it does it will be the present followed by its immediate shift to the past upon having occurred.

  • Where must I go if I want to use my brain and try to learn something? National Geographic, Discovery Channel or Arte are for people with no brain at all who like to think they are learning something in shows that are meant to be simply spectacular and entertainting, but have no educational value at all. Here it is the very contrary: it is much too complex for anyone who does not have any education in that field of learning introduced. We don't have time to process everything because it goes much too fast and it ends up being empty like if it just entered one ear and exited through the other. On TV channels, documentaries have a mediocre overtone, here it has an elitist overtone and it's not better. Maybe it is mentionned somewhere, intrisically or explicitley, that there is a threshold required to appreciate the work PBS does because, in the end, I don't think it is a mark of success to make your audience feel like idiots. I'm speaking on my own account _ I know that, but 1) I'm quite sure I'm not the only one to feel that 2) I think you could _ maybe _ take a little more time to make things clearer. .....Now I'm reading some of the comments under and it really feels like the educational value of this video was quite weak indeed and that, in the end, it was meant to be spectacular and elitist _ what I read is jokes or light-hearted comments. What did people learn from it? I stopped it at 4:00 because I was feeling I wasn't learning anything _ was that due to the fact I am too stupid or is it due to the fact there is nothing to learn. I have been a teacher and I know that when you really want to make people use their brains, you will manage to do it... and that when you don't, you won't. I think I'm going to unsubscribe: I'm very disappointed of your channel where you speak so much and teach so little.

  • the past, present and future exist simultaneously. lets say that we say now that there is a tomorrow and a yesterday. but there is a tomorrow and yesterday that can say the same. you really have to get this. time travel is there. we just havn't figured it out yet.

  • When you travel into the future, time will stand still. You will have to wait for the past to become the present there.

  • Your images of Newton are not just irreverent, they are dismissive and derisive, yet you laud modern thinkers like Einstein. Without demeaning the recent and current thinkers at all, one must acknowledge what our past provided us. Given what shoulders he had to stand on, and how far he saw, that take on Newton is disgusting.

  • simultaneous dynamic now cant be quantifed ? why ? because it is literally nothing ! if at any moment there is something ? it is no longer simulaneous dynamic now ! but it seem human have managed to find a way to .... i dislike cheat but work around. will it be usefull? not iin the near futur because science lack the proper perspective . maybe if science revisit the bad result of the coffee stain experiment they could notice

  • determining the futur of something ? ad i wrote . only up to simultaneous dynamic now ! it sound like a lot. but it isnt a lot in front. what confuse people is that they asume it isnt simultaneous everywhere

    appr ovedappr ovedپیش 14 ساعت
  • simultaneous dynamic now is everywhere at the same time! when we can measure time. it is because something cant keep up with simultaneous dynamic now. ( exemple :light)

    appr ovedappr ovedپیش 14 ساعت
  • it is not your now ! it is times now . everything that can be quantified via time is basicly a retardation of simultaneous dynamic now
