1. Time is not a thing. Someone just made it up. We are just a planet among trillions of other planets. Why is everyone so curius. If something happens a trillion light years way then it will take a trillion light years for us to see it. We already know this, and people still seem to give a shit about it. Time just keeps on going, and if we can't do anything about it, then we shouldn't even give a fuck about it.

3. It sounds like he's talking about parallel universes in the middle of the video
4. 636 , why do we perceive the world in such a temporal way? Because we are the cause of all our effects, and our minds are easily trained from youth to follow a specific system. Early schooling, cultures, social systems and of course that glass box we all jave in our living is really just programming a child into a specific system, its a formula equating to a specific result for all things included. And the american formula happens to be one of selfish over abundance.
   
   If children were taught serenity, by way of earning gratification from selfless acts, then this they would do. Balance would be achieved, harmony would become the human disposition, And would probs end war
5. Here's One for you, 2016 is going out with a BANG!
   
   ;)
   
   Terrorist attack?
   
   We will see how well this Cassandra paradox works out tomorrow shan't we?
   
   Now,
   after this happens, try to tell me Time Travel doesn't work.
   
   If you care to understand how I knew this, I implore fellow students of sacred knowledge to study the Mandukya Upanishad.
   
   Time, Space, Causality, Past, Present & Future.
   
   -it's all One.
   
   Infinitely dividing it's Self into boundless infinities beyond comprehension.
   
   All of these Infinities are still connected as One.
   
   You are that One.
   
   How many decimal places fit between Zero and One?
   
   Just You,
   rather the "I" (Eye) within You.
6. Where's the soothing bearded foreign man
7. I love PBS Space Time, you guys give really awesome (and entertaining) explanations. I just want to contribute a little perspective on the notion of causation in physics.
   
   When you say that the causal relation "corresponds" to a certain kind of spacetime interval, this can be a bit confusing. "Corresponds" seems to mean that there is a one-one mapping. But, clearly, not every event in the past light cone of some event E is a cause of E, in any ordinary sense of "cause." Even the apparent positions of the stars and planets, that some astrologer may take as the cause of the onset of a certain disease, occurred within the past light cone of that onset, so even they satisfy the condition you describe as corresponding to the causal relation. (But we don't think that they were a cause.) Maybe this is a special "physics way" of speaking of causes, but in that case we still need the old-fashioned concept when we search for causes of diseases and other important things. So I think it's better to think of the kind of spacetime interval between two events that you describe as a bottom-line, absolutely necessary--but clearly not sufficient--condition for there being a causal relation between the events. (In fact, it is such a weak condition when it comes down to it, that it is hard to imagine anyone having a causal belief that violates it. Even astrologers qualify!)
   
   (I do understand that if we are talking about events at particle scales, then it might be that every event in the past light cone of E affects E, by virtue of gravitational forces, if nothing else. But that's just not the case with disease onsets, tsunamis, car breakdowns, election results, or most other things we are eager to explain causally.)
8. r u trying to say it's counting by light years almost something Einstein was saying when he said E=mc2
9. My understanding level's distribution was positively skewed during this video if at Y-axis the understanding level and X axis the time actually the running time of that video.
10. please some one help me to understand it in simple way with examples. i did not understand anything, pleas explain me with defination
11. who wants some whisky?
12. if I can't memorize something faster than some other person, does that mean I'm back in space time?
13. Who would have thought that the geezer Einstein's conspiracy theory of general relativity, that says time don't even exist, would be true! Respect!!!
14. If anyone can fully understand and appreciate these set of videos on spacetime, you will have much better understanding of our objective reality which can be the basis of explaining other important phenomena.
15. YouTube the Mandukya Upanishad.
    
    It states the very same Truth in a much simpler explanation.
16. Lol completely lost you at 1:00
17. what's real is what we tell each other...so in mental institution, there is art !
18. This is out the video starts:
    
    1) "Forget everything you know about space and time for a sec because we're gonna start from stratch!" okay then, done
    2) "Spacetime refers to whatever external reality underlies our collective experiences of the space between things and the time betwe-" DOES NOT COMPUTE
19. Thanks helped me a lot in my project.
