Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard ...

It took a full year of testing, experimenting and calculating for them and another group of researchers at Princeton to explain the phenomenon: It was cosmic ... the Big Bang theory, first ...

These cosmic strings could stretch the length of the universe. A piece of this string only 1.6 kilometers long would weigh more than the earth. Others have added to the theory: That symmetry still ...

such as near black holes or during cosmic events like the collision of neutron stars, the effects of gravity can be significantly different and would require Einstein's theory of general ...
