The early universe experienced a phase of rapid expansion, known as inflation. For decades, cosmologists assumed that this expansion was powered by a new entity in the universe, known as the inflaton.

Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

Quantum gravity remains one of the foremost challenges in theoretical physics, seeking to reconcile the principles of quantum mechanics with the geometric understanding of spacetime envisaged by ...

It will take the most sensitive instruments ever imagined to reveal ripples from the Big Bang, but they could change our ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
