Scientists have been using complicated, hypothetical particles to explain the Big Bang, but this theory posits that a simpler ...

Astronomers using the James Webb Space Telescope (JWST) have made a groundbreaking discovery that could validate long-held assumptions about the early universe. The discovery, detailed in a recent ...

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a ...

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 ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

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 ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

For two decades, scientists believed the cosmological constant, known as λ (lambda), was positive. That meant the Universe ...

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 ...
