For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer ...

Add Yahoo as a preferred source to see more of our stories on Google. The nearby Andromeda galaxy with older stars highlighted in blue. A new theory of quantum gravity could help explain why more ...

Gravity is a basic force that affects everything we experience. Watch as a flat earther attempts to explain it without using gravity at all. The explanation starts confidently, then slowly shifts as ...

Since conventional explanations have failed to pony up dark matter, one physicist is looking towards the unconventional. In a series of two papers, physicist Stefano Profumo of the University of ...

Scientists have spent decades trying to understand how gravity operates at its most basic scale. However, no theory has come close to fully explaining it. Now, though, a new theory could finally give ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

A view of the central region of the Perseus galaxy cluster, one of the most massive objects in the universe, shows the ...

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...
