1.3 billion years ago, two orbiting massive black holes, circling each other at 250 times a second, collided in a violent, ...

The curious minds at What If imagine a massive gravitational wave crashing into Earth, revealing the physics, planetary effects, and cosmic consequences.

Mind = blown.

It was quite a leap. Conspiracy theorists are being brought back down to Earth after NASA scientists debunked a wild claim ...

Our understanding of the universe may be completely wrong.

Professor Takaaki Kajita, recipient of the 2015 Nobel Prize in Physics, delivered a public lecture on gravitational waves at ...

"It is exciting to think that Little Red Dots may represent the first direct observational evidence of the birth of the most ...

A conspiracy theory claims gravity will fail for seven seconds in 2026. The science is wrong—but what would happen if gravity ...

The observed near flatness of galactic rotation curves has long been interpreted as evidence for large amounts of non-baryonic dark matter. Here we show that this phenom ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

New simulations suggest early black holes grew rapidly through intense feeding, helping explain why massive black holes appeared so soon after the Big Bang ...
