A black hole can have a mass of 10 solar masses.. How come a neutron star can't have such mass as well?

I'm 99% sure the answer is B. Edit: I base this off the fact that you can use the hubble constant to figure absolute distance to galaxies, and I'm extrapolating that to the size of the universe. This does seem like an odd question.

That's why you haven't gotten a straight answer both times you've asked. D is also closely related to this but I think it's B.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
