Do You Know What Time It Is?
2008 · 49 MIN · IMDB 8.7 · 91 VOTES · DIR. Paul Olding
Overview
Particle physicist Professor Brian Cox asks, 'What time is it?' It's a simple question and it sounds like it has a simple answer. But do we really know what it is that we're asking? He investigates the concept of time, exploring its origins and its limits, and questioning whether travelling through it will ever be possible. Brian visits the ancient Mayan pyramids in Mexico where the Maya built temples to time. He finds out that a day is never 24 hours and meets Earth's very own Director of Time. He journeys to the beginning of time, and goes beyond within the realms of string theory, and explores the very limit of time. He discovers that we not only travel through time at the speed of light,but the experience we feel as the passing of time could be an illusion.

00:00:01 There's an aspect of our lives that we all take for granted.
00:02:57 The Maya didn't have clocks, they didn't know how to build timepieces.
00:05:31 Do you know?
00:08:27 They're, we think, the nuclei of galaxies.
00:10:30 Yes, the length of the day is not 24 hours exactly.
00:13:19 So we choose certain ones to use for keeping atomic time.
00:15:35 Atomic time is the heartbeat driving modern life.
00:18:47 10% of the telescope time per year that I could use for anything.
00:21:06 We're going back in time. You can see the three-dimensional effect.
00:23:43 So, could you describe to the nuts and bolts of the measurement?
00:26:00 You get these very precise sounding numbers
00:28:26 And, at that event, all the particles were
00:30:55 we know as the Big Bang
00:33:20 I'm hoping for when I'm about 60, I can go...
00:35:38 and a little bit more of a second.
00:38:01 Really what you're doing is you're moving through it just in the same way that you can move through space.
00:40:41 a metronome that just ticks the same for everybody.
00:43:24 an experiment was devised to see if the sun causes time to tick differently
00:45:38 The huge mass of the sun bends and curves the space time
00:48:02 relative to someone out in space does something very weird.
00:50:17 Our intuition about time is that the past has happened
00:52:38 If you take Einstein at face value, the future is as real as the past.
00:55:17 on top of it, and another one on top of it and another one on top of it
00:57:37 Did time have a beginning? Or has it always been?
