Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

The science communicator, a disciple of Stephen Hawking, believes it will be decades before we colonize Mars. But he says we ...

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

They show up as a mathematical solution in general relativity, basically as a time-reversed version of a black hole. Some ...

Wormholes are often imagined as tunnels through space or time — shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent and role in shaping the universe.

They shaped the Universe, yet the first stars ever born continue to evade the searches of astronomers like Dr Emma Chapman ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...
