Fusion is based on the same physical reactions that power the sun and stars

The multi-billion-pound project has been hailed as 'game-changing'

The Atomichron, unveiled on October 3, 1956, was the world’s first commercial atomic clock. At a time when timekeeping is more accurate than ever before, A.S.Ganesh takes a look at atomic clocks and the Atomichron…

Nuclear fusion reactions in the sun are the source of heat and light we receive on Earth. These reactions release a massive amount of cosmic radiation — including x-rays and gamma rays — and charged particles that can be harmful for any living organisms.

Letters: Readers respond to an article that argued that the field of physics is too obsessed with discovering new particles

In private, many physicists admit they do not believe the particles they are paid to search for exist, says physicist Sabine Hossenfelder

The researchers show frequencies of spatially separated clocks can be compared more precisely

A newly constructed University of Michigan facility that will be home to the most powerful laser in the United States is hosting its first experiment this week

Gravity as we know it is safe for now. The MICROSCOPE mission sought to test the Weak Equivalence Principle from general relativity in space, finding it held up.

A “folded diamond” doesn’t sound entirely plausible. But that’s exactly what we’ve found inside a rare group of meteorites known as ureilites, which likely came from the mantle of a dwarf planet or very large asteroid that was destroyed 4.56 billion years ago in a giant collision.
