I have broken up the General Relativity videos into segments that are more appropriate for classroom use. Each one is just a few minutes long and they do not have any music. That should make them advertising free as well. The full video is reconstructable via the General Relativity playlist.

There is also a segment on credits with websites and documents identified that can be used for further research by interested viewers: How Fast Is It - 07 - Credits and Research.
