I just don't get it.

According to the theory of special relativity, nothing can ever move faster than light speed.
But due to the expansion of the universe, sufficiently distant stars move away from us faster than the speed of light.
And the explanation is...that this universal speed limit doesn't apply to things that are really far away?
Please make it make sense!

Richard Freymann explaining light

Sounds like it’s not actually Feynman, it AI.

This isn't his voice — it's our tribute to his teaching style, created purely for education and inspiration. No impersonation intended, just deep respect for one of history's greatest teachers. 🙏

Thanks, I didn't notice that. I'll pay more attention in the future.

I actually started watching a video from this channel a while back and was disappointed to learn it wasn’t him. I suppose some people don’t mind and find the videos interesting, but I personally find it disturbing, as though they’re re-animating his corpse or something. 😆
