RE: Astronomy News #05 - Gravitational waves, black holes & star clusters
That's interesting. Especially the part about gravity and gravity waves creating ripples in space time. That's really neat. It's a challenging topic but It made sense to me the way you explained it. When the two black holes approach each other they cause more ripples through space until they combine as one, at which point things calm down again. That reminds me of two water vortexes coming together in a tub or river. I can totally picture that. Nice post!

Exactly :) glad you caught the main idea.
It's interesting that we are usually explaining accretion disks (when stars and black holes eat stuff they create "sucking vortices" of matter) with tub vortices.
Cheers
