The universe exists because matter and antimatter are not good friends. Is there a scientific reason why the universe exists?

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...

Recently, a research team from the Chinese University of Science and Technology achieved a significant breakthrough in the ...

“There’s a lot of meanings for ‘small,’” says Janet Conrad, a particle physicist at the Massachusetts Institute of Technology ...

Astronomers once thought the universe's first stars (made of hydrogen and helium) were nearly all giants, hundreds to ...

That cosmologists cannot agree on one of the most elementary facts about the universe is striking enough. But that uncertainty produces others, too: it makes it impossible to calculate an exact age ...

A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in time, before the Big Bang. Dark matter, then, could be right-handed ...

The first chemical reactions in the wake of the Big Bang have been recreated for the first time in conditions similar to those in the baby Universe.

Astronomers have discovered the most monstrous supermassive black hole ever. At 36 billion times more mass than our sun, it’s ...

For decades scientists believed the universe was built on ordinary matter, dark matter and dark energy. These unseen forces ...
