Astronomers have discovered a vast tendril of hot gas linking four galaxy clusters and stretching out for 23 million light-years, 230 times the length of our galaxy. With 10 times the mass of the ...

For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of ...

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the early universe—and that the universe could start contracting at some point.

A new measurement confirms what previous — and highly debated — results had shown: The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our ...

In the early 2000s, it seemed that cosmologists had solved the largest and most complex puzzle of all: how the universe works. “There was this amazing moment when all of a sudden, all the pieces in ...

LOS ANGELES, Feb. 6, 2026 /PRNewswire/ -- Modern physics relies on "Dark Energy," "Dark Matter," and over 20 arbitrary tuning parameters to explain the universe. A comprehensive AI-driven audit ...
