“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually ...

An artist’s impression depicts the accretion disk surrounding a black hole, in which the inner region of the disk wobbles. In this context, the wobble refers to the orbit of material surrounding the ...

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation ...

But the Big Bang theory predicts that about 5% of the universe's contents should be atoms made of protons, neutrons and ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean ...

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard ...

Day 7 of the 2025 Space Telescope Advent Calendar: A Warped View Through an Einstein Ring. You are seeing two galaxies here, one in front of the other. The more distant spiral galaxy appears warped ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

The cosmos has served up a gift for a group of scientists who have been searching for one of the most elusive phenomena in the night sky. Their study, presented in Science Advances, reports on the ...
