In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding?

In simplest terms, the rate at which the universe expands on paper doesn’t match actual astronomical observations. That speed ...

The Big Bang describes the origin of the universe ... Hubble published his famous paper that confirmed the entire universe was expanding, and that the rate it’s expanding at is increasing.
