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.

A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the ...

Eric Hay, director of field engineering at Bethesda’s Quantum Xchange, breaks down what happens when the technical fields merge — and where DC fits. Quantum foam. With power moves like an IPO from ...

(via PBS Space Time) Spacetime on its smallest scales is a seething ocean of black holes and wormholes flickering into and out of existence—or so many physicists think has to be the case. But why ...

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 ...

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 the ...
