I can give the non-scientific definition:

God ran out of green paint after making the grass green.

Dr. Thaller is a pretty cool person, actually.

Like most women scientists of my Generation, she had to go through an immense amount of crap (crap to the 4th power = c^4), largely from Nerdboys fawning and pawing over a Female with a Brain...............

Well, who else are we gonna fawn and paw?!

Is it so bad that a scientist can be thought of as beautiful? I'm sure some girl somewhere watched Cosmos & crushed on Carl Sagan.

See that green alien at the beginning? Its just like all aliens depicted in film.. Puke Green in colour.. Why are they always green? PREJUDICE.

So, this video is basically saying there are only yellow, white, and red stars?
