Cosmology
Cosmology is the study of our universe and it’s evolution from the beginning to a (possible) end. Major topics of interest are cosmic expansion, the size of the universe, the birth and death of stars and galaxies, dark matter, whether our universe is just one of many in a multiverse, and how to measure distances.
Black Hole Universe: Did Our Cosmos Bounce Instead of Bang?
New research proposes our universe formed from a gravitational bounce inside a massive black hole, not from a singular Big Bang creation.
