Shouldn't the densest objects in the universe be black holes rather than neutron stars?

I think it mainly depends on the definition being used; I'll try adding it as a type-in though

Couldn't figure out why "Cosmic Background Radiation" wasn't accepted. Is it really necessary to include "Microwave" to prove that you know the answer?

Fair point - if I'm being completely honest, I didn't really know how to add type-ins. If you could give me some advice on how to, I'd be grateful.

for the closest galaxy question, either change the answer to Canis Major Dwarf or reword the question to something like "closest MAJOR galaxy".

A quick google search tells me that the status of Canis Major as a galaxy is somewhat disputed. I think maybe that answer should be accepted, but I think Andromeda is a better definitive answer.

It seems to be disputed so like AlmostAGenius proposed, I'll add it as a type-in but keep Andromeda as the main answer

Agree with Sumguy. I might add a few type ins for that one. I think just “Background” should work for that one. Also, I’m a little skeptical about the dark energy question. Because “composed” means “made up of” some substance, and I don’t think I would classify dark energy as a substance.

Good point - do you have any potential rewordings in mind?
