... hole in the observable universe. This is what we call a black hole (Figure S3.15). Note that Newton's view of gravity does not really have any analog to a black hole, because it does not envision the possibility of holes in the universe. Thus, a black hole is a place where spacetime is so curved tha ...

... This leads us to the possibility that the big bang wasn’t a tiny dot that expanded. The universe might have thinned out and thinned out until a ‘parallel’ universe just fractions of an inch away could close and touch our universe. This would have filled the universe with a tremendous amount of e ...

Compact stars are stellar objects with small volume for their mass, which means very high density. For instance, neutron star ...
