Dark matter, the invisible substance that shapes the Universe, may have had a far more dramatic beginning than scientists once believed.

Our common understanding of the universe tells us that all matter and energy were created at the beginning of time during a period of rapid inflation called the Big Bang. However, in 2023, Katherine ...

About a year after launching into orbit around the Sun, the James Webb Space Telescope began imaging an abundance of little red dots, which scientists called, um, “little red dots.” I know—not only is ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

The Big Bang is often imagined as an explosion from a single location, but modern cosmology shows a very different picture. Space itself expanded, meaning the universe had no center and no preferred ...

Investigations into the unknowns of space and time -- and abstract questions around early universe cosmology relating to the Big Bang, black holes and universe expansion -- are focal points of ongoing ...

The mysteries surrounding the origins of the universe have long intrigued scientists and philosophers alike. New research, published in the Living Reviews in Relativity, introduces an innovative ...

The earliest acoustic vibrations in the cosmos weren’t exactly sound – they travelled at half the speed of light and there was nobody around to hear them anyway. But Jim Baggott says from the first ...

Gravitation and hot big-bang cosmology / J.D. Barrow -- Euclideanized Einstein-Yang-Mills equations, wormholes and the ground-state wave function of a radiation dominated universe / O. Bertolami and J ...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...
