  • Excellent video

  • @hippiechickie18 That is a very good question. The answer is yes, but again it is a matter of relativity. A clock on circumference of a spinning disc will be observed to run slower than one at the centre. Likewise, a ruler on the circumference oriented in the direction of motion will appear shorter than one that is aligned at an angle.

  • thanks for uploading waiting for the whole documentary

  • Yay for relativity. I thought this was common knowledge :|

  • Wooo Loves me some Relativity!

  • @xxxhkh117xxx It is true, can be experienced on quick bikes. That is why so addictive biking is.

  • @xxxhkh117xxx Maybe the place of deceased souls. Anyone reached it could never come back.

  • Is there a way to subscribe just to BBC Four?

  • Does this work if something is spinning instead of moving in a linear path?
