Do the Past and Future Exist?

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.

  • its like stars. The stars we see now are actually stars from years ago. The closest star to us Alpha Centauri takes 4 years for its light to reach us. So when we look up and see Alpha Centauri we are seeing it as it was from 4 years ago. Space time kills me 😂

  • What if there are two entlagled particles, one still and the other traveling almost at the speed of light. Than we trigger the collapse of the state of one particle, does the other particle that is in a different time slice collapse in the same "time"?? To me it's almost like there is an other time dimension that rule on top of the relativity.

  • Past, present, future, exist simultaneously, within a margin of error. You, in the present, can accurately "predict" your future to some point in time, within the margin of error. The future beyond the margin would become too uncertain to be useful. By the same token, you should be able to travel back in time, outside of the margin of error. Your actions would not affect the present because the margin of error would be too great, thus changes in the past place no effect on your present. However, you must leave the past when you come close to the margin, or else you would risk changing the present AND the future.

  • I recall from a college philosophy class that this notion of eternalism has roots in some eastern philosophy (can't remember which). I still remember trying to write an essay explaining the theory but being completely unable to conceptualize time as anything other than a temporal sequence. Guess that's why I was a history major.

  • The past is only a memory, the future is only foresight. Because we have a mind that can remember and predict. Things with no mind exist as a constant thing, it just happens to be moving. And we measure that motion. Time is the measurement of motion. With no motion theres no time, with no mind, theres no one to measure, so it only exists as a conscious measurement of motion. That's the definition of time. Thanks

  • Finally!!!! I've been trying to say this for over 20 years. You got it. Every particle in the universe is nothing but billiard balls (and the118 elements in the Periodic Table they create), all with exact physical properties, calculable to whatever variable we have the capability to measure. Picture a never ending or beginning book, already written, and you are an energy wave flowing through this book. The future, past and present all exist, but you are only perceiving where, and when your energy wave is, in this book. Which is amazingly awesome, since the reverse of this in the equation that is the reality before us, means, all the physical properties of everything, has absolutely no choice but to do what they do and be where they are, based on the parameters of those billiard balls physical laws. There is nothing but the Aether. Saying that the vortices and waves are particles, is like saying a whirlpool in the ocean is matter. Next subject, consciousness and determinism, and the millions of forms of life.... from their perception.

No matter which decisions you make, I can guarantee you the universe already knew what you were going to do and totally agrees with whatever decision you make. Even if you change your mind just to be obstinate, it was predetermined.

Stockholm guys, where are you? Is this possible that the future and the past have relevancy only when applied to one thing since the clock of everything is different, perhaps by the tiniest amount imaginable, because nothing is really in exactly the same gravitational field or have exactly the same velocity in their moving timeline?

And I saw myself older. Which also came true. And it's all around now. I got no devices or equipment or anything. I also had other premonitions, but they were abstract. But, I have travelled to underground army bunkers. And used other people's eyes and could hear their thoughts. I respect their temples, and the gift I have, by not making them look around the corner,just because I want to see. So I learned to jump from temple to temple. I'm still wondering how.

  • Motion isn't required for another observer to experience a different present from you though because the information itself must travel at the speed of causality. The second observer only need to be sufficiently far away. A second observer at the event horizon of the observable universe can be completely stationary relative to you, and yet their light cone will only intersect with yours billions of years from now. When we look into deep space, we see the CMB, we are literally looking into the past. Distance in every direction sends us further and further back into the past. The idea of simultaneous events is ridiculous if you are thinking about the CMB. The question of "what's there now?" is a strange question to even ask when we can only see the birth pangs of the big bang. Is it more universe? Impossible to verify. Probably? Maybe it's literally our own past traveling along a curved time dimension. There are questions about whether or not the universe repeats or folds back on itself spatially (I'm currently reading Janna Levin's "How the universe got it's spots), but I have yet to see anybody demonstrate say, a time torroid, or a time sphere. Like, perhaps spacetime is spatially flat but curved only in the time axis. This seems to be the case, since the further away you go, the further back into the past you can see. Actually there might be something there... The question of gravity being like acceleration, what if it's actually something really simple, like mass causing expansion of spacetime into the future along the time axis. The idea that massive gravitational objects cause time to slow down may actually be the wrong interpretation: what if the inverse is true, that mass literally causes acceleration-- but along the time axis-- away from the past we see in the distance, moving "inward" in the time sphere toward the "center" (which is of course everywhere... spatially, but not in time, remember that objects that are distant are in the past, this may be a purely geometric function of curvature of the time part of spacetime), and the corresponding effect would be the same as pushing distant objects further away, and further into the past. A massive object doesn't experience time more slowly, it is accelerating the matter that is there into the future, and the edge of the observable universe increases it's distance further into both the past, and space itself, which to observers on a less massive planet somewhere it would appear that time is more slowly passing. A black hole is like the bow wake that forms around a supersonic jet, but the motion of travel is along the time axis. So then if gravity (which is equivalent to acceleration according to relativity) is a literal acceleration, but along a curved time dimension, inflation is perhaps also caused by mass itself... acting in large quantities to both accelerate towards one another, and push the distant past further into the past, and time itself, are all just different aspects of one fundamental property of the curvature of the time dimension of spacetime. So time, gravity, and inflation are all fundamentally geometric properties. And then finally, if we can actually think about time as being a 4th spatial dimension along a hyper-spatial axis, it is entriely possible that a black hole and the edge of the observable universe may be connected, similar to how a mobius strip has only one side, or how the inside becomes the outside of a Klein bottle. A mobius strip represents a 2-d surface bending into a 3-d space to invert itself. A Klein bottle requires a hole for the 3-D bottle's inside to become the outside. Without a hole, it would need to bend into a 4th hyperspatial dimension, which, if we are serious about time being a geometric spatial dimension, could well be the extra dimension for 3-D space to bend back on itself to form a spatially compact, finite universe, but instead of shaping glass, we are shaping the fabric of spacetime. The inside is the present, always accelerating toward the future due to some fundamental property of mass, the outside is the past, literally moving away from us due to expansion. Or maybe that's a load of rubbish, and I should stick to Biology.

  • mistaking observation of different rates of events as those events seems at the heart of this blockhead stupidity. 1. you assume a motionless block and then you talk about motion as if that can make any sense at all. you don't explain how we can move through slice by slice and still exist in both the past and future, this is the first fundamental stupidity. You can't have both motion and motionless. WHAT is moving in a block universe? you talk about our consciousness being smeared out over many slices... how? what is moving? what is consciousness? are you saying you believe in a soul that is not physical as this is the only way to make sense of something moving through a motionless block... you blockheads just assume this and don't bother even trying to explain it in terms of physics cause if you did you would see the instant stupidity of it. 2nd you mis-interpret the light cone, in an eternal present universe, distorted by motion and gravity and acceleration, no one is ever outside the present and so no one can ever see another's future... they can disagree on when things happened but the lorenz transformation can be used to understand the different perspectives and acknowledge only ONE event actually occurred, even if there may be disagreement on when... which I believe can be resolved as well. After all, we may not know what is going on in Alpha centauri right this second, but when information arrives we won't be stupid enough to think it did not happen 4.3 years ago as that is when that information comes to us. We won't ever see something from anyones future, ever.

  • Quick question which has been bothering me for a bit. If time is relative and the universe is supposedly 13.9 billion years old, the universe is expanding and celestial objects move around the universe and incredible speeds. Does that mean the universe' age is not evenly distributed, such that 13.9 billion years would be the age from our perspective? I would assume the age 13.9 would be the universal age. Can someone help me grasp this better?

Go outside, create a need to wash your clothes, fold them, unfold them, iron them, wear them. Did the wrinkles exist? This is fallible logic at best, or heresy that any rational atheist is capable or recognizing at worst. Those wrinkles and your effort, though perhaps you get bored ironing, would not be "erased", we develop cognitive skills through practice and application. Applying the lack of logic/reasoning in the video description- what on earth would the need be for an iron, or a shelf? @PBS Space Time HOW MUCH TAX MONEY ARE YOU TAKING FROM US? WHAT'S YOUR GOAL?

  • 3:00 So because we can imagine it means it is more true? Similarly to the time traveler observer collapsing the wave function, his paradoxical state still applies when it come to observing time. Any reality, any consciousness and any information all stand on this constant universal and paradoxical framework that applies to every theory that can exist: We can't prove that a proof was or was not created just before we observed it. It is paradoxical not only in its direct meaning, it is paradoxical because it will always be the case no matter the information we have about any reality from any state of consciousness about any type of information, but it will never be atteignable, pinpointable, its meaning undermine its own existence.

  • It seems to me (a non-physicist layman) that this all describes the limits and subjectivity of observation, given relativity and the speed of light, rather than describing the nature of time itself. What if all those multiple points of observation spread out across the current time slice belonged to a single consciousness? If we pretend for a moment that consciousness was not limited by the speed of light it would be possible to know of something happening millions of light years away even though it wouldn't be visible to all of those observation points for millions of years. Doesn't that imply that this is really just about our ability to perceive?

And shouldn't that tell a more accurate time for both galaxies? I mean like in Einstein's train, where 2 lightning bolts hit the front and back of the train and you're in the train, you should see a discrepancy. But what if there were entangled particles on both ends of that train, each connected to one in your hand? And once lightning hits them, you'll see the change immediately? I mean is time simply information? Isn't it causality?

  • It took me a few watches to understand, but the video get's wonky around 8:00. Why is what's present only based on what you are currently observing? If we observe a super nova and know how far it is, we know how distant in the past it exists. We know that it didn't happen "now," we would know exactly when it happened and where. If everyone agreed to calculate the relative distance and speed of the objects distant they're observing, we would all agree on the same exact now-slice. This would be the same no matter how far away or fast traveling the other observers are.

  • Without meaning to sound hyperbolic, I suspect that was the most facetious ending to a video ever. Bravo, Cheers! ;) Well, if time doesn't really exist then maybe I am being overly hyperbolic...Hmmmm... Future, Past and Present do not exist, only the multiverse at the quantum level. They all exist together as one wave rippling giving way to the space/time illusion that provides the course of entropy. All space/time, now, then, there, was, & what will become is just the same as the space left behind between two pizza slices. The illusion is that there are two slices but the truth is that it's a pizza even if it's sliced, diced or chop suey-ed. The basic fundamental laws (pizza) never change through entropy, concluding that ALL is ONE and it's and not separated by time/space entropy. This concludes there is but one dot expressing itself in unlimited possibilities that the course of entropic expression will allow with constraints of physics law.

Fact you can touch and see, and yet your mind does not measure the space sticks sticking out of the ground have stuck. You are not conscious of fact, you are conscious of the feed 2020 fed you. The illusion is what you are conscious of, and the illusion of time can only provide the illusion of mind. You are not conscious you are not conscious until you are conscious-0-of beginning consciousness. Can you tell me the moment your consciousness began? Then how do you know it has?

  • Mind blown. Its as if information from carrying light is filling up the universe in all 'time like' tenses. Maybe the growing space between everything is just memory allocation.

  • Isn't the universe expanding in all directions and not just one, cone form? Whats behind us if we are looking at the circle of the cone?

  • Probably a stupid question, but is it possible that some of the missing or hidden mass we believe exists based on models, could just exist in the "future" part of the block universe that we have yet to traverse through? Like, if it didn't follow the same path through the block universe that we are going through?

  • If you sit perfectly in the on the event horizons of two binary black holes (kinda like their barycenter point), would you never age?

  • The past existed, the future is yet to exist, and time doesn't stop, therefore there is no present as time is always moving forward to a future that does not exist yet!
