Huh. Certainly an interesting choice for observers around a black hole. Also a fascinating video. And now I find myself thinking about how Dash's mane could be used to illustrate gravitational Doppler shifting.

Thanks for sharing this!

4789053 that was an interesting choice of observers. I know that they wouldn't have been my first choice when making the video.

Hmm... Could we use Rainbow Dash to illustrate the effects of decreasing ambient temperature?

20% cooler!

The pony is now at an external temperature of 240K...

The pony is now at an external temperature of 192K...

4789053 I bet Rainbow Dash wouldn't even need the rockets to hang out with Fluttershy at the edge of the Black Hole.

And she can breathe in space. She probably taught Batman how to do it.
