In the name of open science, the multinational scientific collaboration COSMOS has released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, with data ...

New observations from the James Webb Space Telescope (JWST) suggest the cosmos may be much older than once believed. For decades, scientists have held that the universe is about 13.8 billion years old ...

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, ...

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

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

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.
