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.

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, ...

Quantum gravity is notoriously slippery. While the Standard Model successfully describes three forces of nature, it doesn't include gravity, so gravity still has no consistent quantum theory. To make ...

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 ...

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 ...

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 now appears that there really isn’t such a thing as space that “contains” things, and there isn’t really such a thing as time during the course of which events occur As usual, the Bard nailed it in ...
