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

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

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

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

Scientists at the University of Waterloo have uncovered a bold new way to explain how the universe began—one that could reshape our understanding of the Big Bang. Instead of relying on ...

The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

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

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 ...

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

Artist’s interpretation of the cosmic distance ladder — a succession of overlapping methods used to measure distances across the Universe, where each rung of the ladder provides information that can ...
