When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact ...

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

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

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

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Astronomers have spotted what may be one of the universe’s earliest barred spiral galaxies — a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, ...

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.

Rubin Observatory detected 800,000 cosmic changes in one night, launching its 10-year mission to create a real-time movie of the universe.

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

Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion ...

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...
