Full transcript

1. 0:00Time doesn't exist,
2. 0:01>> [music]
3. 0:01>> and I'll explain it.
4. 0:03We think of time like a river flowing
5. 0:04forward. You live in the present, the
6. 0:07past is gone, and the future hasn't
7. 0:09happened yet.
8. 0:10But science says the past, the present,
9. 0:13and the future are all happening right
10. 0:15[music] now.
11. 0:16How is this possible?
12. 0:18Well, science also says the universe is
13. 0:20a giant 4D [music] block.
14. 0:23Your birth, your breakfast, and your
15. 0:2580th birthday all exist at once,
16. 0:28anchored and never disappear.
17. 0:30This means that the time you know
18. 0:32>> [music]
19. 0:32>> doesn't exist.
20. 0:34Gravity affects time. It affects it so
21. 0:36much that our own Earth's core is 2 and
22. 0:391/2 years younger than the surface.
23. 0:42For an observer outside [music] looking
24. 0:43in on your life, your life has already
25. 0:46happened.
26. 0:47You aren't moving [music] through time.
27. 0:48Your consciousness is just riding a
28. 0:50track that's already been built.
29. 0:53If the past, the future, and the present
30. 0:55[music] have all already happened,
31. 0:58do we really have free will? Or are your
32. 1:00choices [music] set in stone? It seems
33. 1:02like your life is just a roller coaster,
34. 1:04and you're the only [music] passenger.
35. 1:06So, just enjoy the ride.
