The universe seems to be expanding faster than it used to, meaning it's about a billion years younger than we thought, a new study by a Nobel Prize winner says.

In the diagram below, the left edge represents the beginning of the universe, and time progresses as you move to the right. The gradually widening cone represents the expansion of the universe.

The Hubble telescope precisely measured the rate at which the universe is expanding by looking at relatively nearby galaxies, and in 2018 found a higher rate of 72.8 km/s/Mpc.

For decades, scientists have discerned that the universe is not only expanding, but accelerating. But this evidence doesn’t always square with models, throws flags with things like the cosmological ...

The expanding universe is one of the most fascinating and far-reaching discoveries in modern science. At its core lies a profound realisation—that the cosmos is not static but constantly ...

Dark energy, the mysterious phenomenon that powers the expansion of the universe, may undergo periodic 'violent transitions' that reverse the growth of the cosmos, a new pre-print study hints.
