Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...

Albert Einstein is synonymous with genius and groundbreaking ideas, often immediately linked to his theories of relativity. Yet, when the 1921 Nobel Prize in Physics was awarded to him, it was not for ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

It might not be obvious to those of us only grappling with more mundane concerns, but for cosmologists bent on unlocking the universe’s deepest secrets, there’s no shortage of problems keeping them up ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...
