Question

What is the general distribution of galaxies in the universe?

a. They are grouped into clusters and superclusters, which in turn are distributed around huge, apparently empty volumes of space.

b. They are scattered more or less randomly and uniformly throughout space.

c. They are grouped into clusters and superclusters, but the superclusters are scattered more or less randomly and uniformly throughout space.

Answer 1

Kids, if you're going to ask questions from your homework, at least make it look like you've put forth an effort to find the answer on your own.

Answer 2

no C is the correct answer

galaxy clusters do exist- in this sense, you're more likely to find a new galaxy by looking near a known galaxy than in a random place.

however, on "huge" distance scales, such as hundreds of megaparsecs, the distribution of galaxy clusters is more or less uniform. evidence for this comes in the galaxy maps:

you can see from the image (each blue dot is a galaxy!) that there is a little bit of order, but on such large scales, there are no "empty volumes", like answer A suggests.

Answer 3

A is the correct answer.  Although why is a puzzle.

Answer 4

A is correct.

When you look out, galaxy groups are strung out on spider web like structures, with super clusters where strings come together.

Computer models of the evolution of the Universe show this structure evolve. As far as i know, this structure is the result of gravity. Check out the video.
