Thread:User talk:WaitingforGodot/Brian Cox

It occurs to me that if you really want your brain baked, you need to search out some before-he-was-famous Cox. Specifically if you can find the episode of Horizon titled "What Time Is It?". They go into a great explanation of how the finite speed of light makes the usual trope of "we're seeing the sun as it was 8 mintues ago" quite meaningless, if not a little wrong - it's like our concept of "now" also extends from us at light speed because no information can travel faster than that. If you can wrap your head around that, you have relativity in the bag. I don't know why I suddenly thought of it just now, it just popped in there.
