The most precise measurement of the expansion rate ever made suggests an unknown force may be affecting the universe.

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion ...

The most precise measurement yet of how fast the Universe is expanding shows we have a real and serious problem on our hands.

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A ...

The Hubble tension, the stubborn discrepancy between two methods of measuring how fast the universe is expanding, has long haunted modern physics. Some scientists ...

The universe is stretching apart faster than our current theories of physics can explain, and a new study has just confirmed that the discrepancy is not a fluke. By funneling decades of data into the ...
