Hubble’s Law
what is the Big Crunch

what kind of universe model do we live in
accelerating universe
what is dark matter

dark energy
type of matter which has a anti-gravity effect
what kind of model of the universe would end in a big crunch
a closed universe
what kind of model of the universe would have a critical density
flat universe
what kkind o fmodel of the universe would result from there not being a high enough density
open universe
