For decades, scientists have relied on a popular idea referred to as cosmic inflation to explain how the universe began and ...

In this video, we explore the origins of the first atom, tracing back to the big bang, where immense energy condensed to form ...

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 ...

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

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 ...

A faint radio "whisper" from ancient hydrogen reveals the universe was heating up long before it filled with starlight.

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

"If the model holds true, it could mark a new chapter in the way we think about the birth of the universe." A radical new theory regarding the origin of the universe suggests that gravitational waves, ...

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 ...
