- 03:34: Because of the relativistic Doppler effect.
- 03:37: The relativistic Doppler effect classically changes the wavelengths of light, blue-shifting approaching material and red-shifting receding material.
- 05:53: At the same time, the relativistic Doppler effect speeds it up.
- 06:08: The relativistic Doppler effect will speed up an approaching clock by 1 over 1 minus v on c.
- 06:46: ... you think of just the time dilation, and not the Doppler effect, you get that the moving clock is always around 13% percent slower than ...
- 07:12: ... away far more slowly due to the combined effect of time dilation and the Doppler effect. ...
