All the tools for measuring it in the local, recent Universe give fairly consistent results, around 72 to 74 kilometers per ...

The universe is expanding, and physicists cannot agree on how fast. In a preprint posted in late May 2026, the H0 Distance ...

A difference of a few kilometers per second might not sound like much. In cosmology, it has become one of the field’s most ...

In this video, we explore the Big Bang theory and common misconceptions surrounding it. The Big Bang theory suggests an ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still ...

Cosmological expansion is widely treated as a proven fact. It is not proven. For nearly a century, cosmology has told a ...

An international collaboration of astronomers has produced one of the most precise measurements yet of how fast the local Universe is expanding. The result deepens one of the most significant challeng ...

A new analysis has found that the local Universe is expanding faster than predicted from the early Universe, confirming a long-standing mismatch between ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...

Black holes that formed before the Big Bang could still exist today as ‘cosmic fossils’, potentially helping to explain the ...
