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 ...

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 ...

Measuring acceleration due to gravity at the site, researchers found it was a surprising 9.7639 meters per second squared.

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 ...

According to the team, the new approach can explain how the universe's initial inflation can naturally arise. But it comes with highly unusual "ghosts" that we don't know how to explain.
