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.

  • 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?

  • Video posted Oct 13th, 2020. Perhaps I will watch it in November when I am with another person as we continue to build a lasting relationship. Yes, the past and future exist. Do you want to be removed from history? I can remove this inquiry from my browser history, delete this comment, though the time I chose to make in the past for this comment exists for a reason. And I'm choosing to publish it for a reason. And when you read it, it will be published. What a nonsense title. How are your children doing? Grow up, and perhaps appreciate that your parents sacrificed their own life so you could have yours. With love, develop a rational line of reasoning. We grow through and with the present moment. 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? I SEE YOUR WITCHCRAFT ATTEMPTING TO CAST A SPELL... POSE A QUESTION, AND AS YOU CLEARLY STATE, THE ANSWER LIES. NOW PUT ON YOUR MASK AND GET IN LINE, THE PIGS TROUGH YOU THEIF FROM IS DIRTY AGAIN. IT'S GOING TO BE QUITE THE CLEANING PROCESS.

  • 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?

  • What about quantum entanglement clocks? What if a particle clock is entangled to another clock from a galaxy far far away? Shouldn't that be immune to the lightcone effects? 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.

  • the fundamental flaw in this presentation although I really do like it and think 99% of it is accurate, is that there isn't a lack of civilizations in the universe as a whole or even just in our own local galaxy for example. They're just hiding from us and sometimes they don't hide because ... well just look up alien encounters and alien abductions in addition to reading declassified US Government documents regarding the subject and you will see that we are not alone and never have been.

  • So, relative perception rules out a deterministic universe, but all star and planetary predictions are deterministic. Is this because you use the earth as a perception point so all people have the same perception. Does this make the atmosphere a relative boundary. Is this a comparable to the boundary between the standard model and quantum mechanics.

  • You cannot talk of what you have not measured, so until you define Eternity 10,000,000,002,020 you cannot be defined by it. Time travel begins like this: 10,000,000,002,020. Did you feel that? You just moved Eternity. You moved it from thought to sight- space travel!. There is no 2020 because trees are there 5000 years and they are fact. 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?

  • Past and future seem to be just configurations of the available mass / energy. These configurations change according to the known physic laws. Each of the "slices" in time are just configurations of the available mass/ energy. And time is a local phenomena. Einstein says so. There is no "universal time" for the whole universe. The whole idea of "existing past" or "existing future" universes goes against all current know physical laws.

That's ironical, because actually, only information, for the time being, has been PROVEN to be able to travel faster than light. Atoms entanglement proves it. You act on one atom, and its entangled atom, whatever the distance between these two entangled atoms is, will react the same way. Therefore, information CAN travel faster than light.
