New Theory Says the Universe Might Have Started Inside a Black Hole ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

A new analysis of ‘cool’ spots in the cosmic microwave background may cast new doubts on a key piece of evidence supporting the big bang theory of how the universe was formed. Two scientists at The ...

Bell Labs built a giant antenna in Holmdel, New Jersey, in 1960. It was part of a very early satellite transmission system called Echo. By collecting and amplifying weak radio signals bounced off ...

This week, an international team of more than 160 astronomers working with the Atacama Cosmology Telescope released three preprint papers submitted to The Astrophysical Journal unveiling the most ...

In the early 2000s, it seemed that cosmologists had solved the largest and most complex puzzle of all: how the universe works. “There was this amazing moment when all of a sudden, all the pieces in ...
