For decades, scientists assumed that the expansion of the universe was powered by a new entity, known as the inflaton, but ...

Quantum foam (also referred to as space time foam) is a concept in quantum mechanics devised by John Wheeler in 1955. The foam is supposed to be conceptualized as the foundation of the fabric of ...

According to new research, the earliest seeds of structures may have been laid down by gravitational waves sloshing around in ...

A new study suggests that the cosmic web could have formed without relying on inflation driven by a scalar field. Instead, it ...

One of the prominent approaches to quantum gravity is the spin foam model, which provides a way to visualize and calculate the quantum states of spacetime. Recent research in this area has focused ...

From slow neutrinos to quantum foam, these experiments are hoping to finally answer it What we’re still lacking, however, is a quantum field theory of gravity. Alone of the four forces ...

Within that backdrop, the quantum foam is doing its usual thing, which is to shake up space-time at submicroscopic scales. Those fluctuations create gravitational waves, which are ripples that ...

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.
