Astronomers claim in a new paper that star motions should make it easy for civilizations to spread across the galaxy, but still we might find ourselves alone.

A two-player game can reveal whether the universe has an infinite amount of complexity.

No new particles have been found at the Large Hadron Collider since the Higgs boson in 2012, but physicists say there’s much we can still learn from the Higgs itself.

Brief cosmic blips called fast radio bursts have puzzled astronomers since their discovery earlier this decade. Now researchers appear to be close to understanding what powers them.

A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth’s climate past a disastrous tipping point in as little as a century.

Physicists have devised a holographic model of “de Sitter space,” the term for a universe like ours, that could give us new clues about the origin of space and time.

The new work promises to give researchers a better grip on the core mystery of quantum mechanics.

Priyamvada Natarajan has pioneered the mapping and modeling of the universe’s invisible contents, especially dark matter and supermassive black holes.

Perfect black holes are versatile mathematical tools. Just don’t mistake them for the real thing.
