Cosmologists have traced the Big Bang’s earliest moments with great care, from the explosive inflation that set spacetime in motion to the period of newborn atomic nuclei known as primordial ...

Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, ...

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 ...

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

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...

Scientists may have found a new way to unlock the vast secrets of the Big Bang—the cosmic event thought to have kicked off the expansion of the universe billions of years ago. The revelation came in ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles of matter and antimatter decay. By Kenneth Chang Understanding why matter ...

The secrets of black holes and dark matter could lie before the Big Bang, a new study of "bouncing" cosmology hints. When you purchase through links on our site, we may earn an affiliate commission.

In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

"Challenging long-held assumptions is essential to scientific progress." A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

Our humble blue planet came into being with the Big Bang — the sudden expansion of the universe outwards. Now, according to astrophysicists and cosmologists, Earth and all of its celestial siblings ...
