Most crucially, inflation explains how we got our large-scale structures. The act of inflation took the quantum foam of space-time and expanded it to larger scales, laying down the gravitational seeds ...

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 ...

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 ...

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 ...

Most crucially, inflation explains how we got our large-scale structures. The act of inflation took the quantum foam of space-time and expanded it to larger scales, laying down the gravitational ...

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 ...
