Very early dark energy (vEDE) may have accelerated the universe’s expansion just 380,000 years after the Big Bang, new ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

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

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

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

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 ...

Rice University researchers have captured the temperature profile of quark-gluon plasma, the ultra-hot state of matter from ...

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 ...

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 ...

Who Banged the Big Bang! reinterprets the Big Bang theory not only as the birth of the universe but as a profound metaphor ...

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