60-second adventures in thought - The twin paradox (5/6)

60-second adventures in thought - The twin paradox (5/6)

Twins are born at the same time, so they should both reach the age of 50 at the same time, right? Actually, that depends on how fast they are moving relative to each other according to Einstein's theory of relativity. Voiced by comedian David Mitchell.

Latest comment: this video does not state the PARADOX. the thought experiment is not complete here. supposedly, you should think about it from the reference of Bert. In his position is used as reference, then he has zero velocity and instead, the whole univers, including Al, would be the one moving very fast and hence would have the slower movement of time. So the paradox would be that Al is older in the first point of view. But it would be Bert in the second one. So who is really older?

Not really a paradox at all. (and I'm getting seriously bored with the BBC ad kicking in after every clip)
