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

Using data from space telescopes and other instruments, astronomers, cosmologists, and astrophysicists are able to deduce and ...

The universe has no brain. It has no gray matter, no nervous system, no neurons firing electrical impulses—and yet, that ...

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...

Then, by comparing that distance to how fast the galaxy is moving away, they get the expansion rate for that part of the universe. This gives a value of around 73 kilometers per second per megaparsec.
