>>16717666 (OP)>Is the universe infinite in every direction?As far as we can tell, yes
> If matter is finite and you were to go far enough in space would you eventually find yourself in an infinite dark void of nothingness? If so why did all the matter cluster in a specific region of space?Assuming the big bang model is correct, the speed of inflation exceeded the speed of light (it can do that, I will bot explain how right here), so there exists matter outside the range you can reach by traveling at the speed of light, and the universe is still expanding so you will never outrun that matter
Now there are unclear points on the exact mechanics of inflation, but if you kept travelling outward at almost light speed (if you're travelling AT lightspeed, time doesn't pass) you will keep meeting matter, but it will be increasingly sparse
