The Big Bang is often described as the explosive birth of the Universe – a singular moment when space, time and matter sprang into existence.

In this framework, our entire observable universe lies inside the interior of a black hole formed in some larger “parent” universe. We are not special, no more than Earth was in the geocentric ...

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

A team of physicists have proposed a new cosmological model – dubbed the "black hole universe" – that suggests that our universe did not begin at the Big Bang. For a long time the universe was ...

The emergence of DeepSeek, a large language model developed in China, is a landmark in AI development. Much like the symbolic hammer throw in Apple's advertisement in 1984, DeepSeek represents a ...

New model. Our new model tackles these questions from a different angle—by looking inward instead of outward. Instead of starting with an expanding universe and trying to trace back how it began ...

The universe expands over time, but how fast it’s expanding seemed to differ depending on whether you looked early in the universe’s history or the present day. If true, this would have presented a ...

Today’s standard cosmological model, based on the Big Bang and cosmic ... of a black hole formed in some larger “parent” universe. We are not special, no more than Earth was in the geocentric ...

New research challenges everything we know about the Big Bang. A new theory has emerged, called the black hole universe, that offers a radically different view of cosmic origins ...

Scientists have made a new calculation of the speed at which the universe is expanding, using the data taken by the powerful new James Webb Space Telescope on multiple galaxies. Above, Webb’s ...

In the 1970s, studies of the motions of spiral galaxies led to extra matter, known as dark matter, being added to the big bang model. However, nobody knows what it is.
