How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

Theorists have found that a “warm” version of cosmic inflation is consistent with known physics, linking it to the hunt for ...

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

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 ...

The birth of the universe has been a question that has puzzled scientists for centuries. In a groundbreaking study published ...

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 ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and ...

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

The combination gives rise to new possible cosmologies in which the universe, say, five seconds before the big bang expanded at the same pace as it did five seconds after the bang. But the rate of ...

It will be a view unlike any other — completely invisible, exceptionally quiet and utterly transformative. Deep in the first moments of the Big Bang, the entire cosmos shook and rumbled. Those quakes ...
