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 ...

Scientists say microscopic wormholes could explain discrepancies in cosmological constants and affect our understanding of ...

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 ...

(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 ...

A new reality might be produced by every possible quantum interaction. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Some interpretations of ...

This is a really cool observation and constraining theory is also great, but it does get a little frustrating that we keep merely getting tiny upper-bounds on possible effects that theories predict, ...
