how is it that inflation allows 2 galaxies to collide, I thought it was pushing galaxies away? So LHC will never be able to detect this because it is to hot of a process? Thanks for the course.

Vortices occuring in dark matter can be mistaken for wormholes and small black holes.

Dynamic friction can be snowbanks, piling up against each other as they do in the skies of Nunavut. Yes, in the sky, somehow.

Clumping is really good clarity in science.

Thank you to Prof. Koury for this course.
