There are people who believe the universe is infinite with an infinite number of stars and galaxies. There are some very valid mathematical explanations of why this can't be true. However, as in many other theories of the universe, we simply don't know.
The most distant objects we can see are over 30,000 light years away. Some theories say that the universe is expanding at close to the speed of light, so we can't even conceive of traveling to the edge of the universe to measure it

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
