There may be an infinite amount of energy locked in the vacuum of space-time. So could we ever harness this energy for anything useful? The idea of vacuum energy comes from quantum field theory, which ...

In every bit of nothing, there is something. If you zoom in on empty space and take out all the planets and stars and galaxies, you might expect a pure vacuum, but you’d be wrong. In­stead you would ...

In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed ...

The controversial idea that our universe is just a random bubble in an endless, frothing multiverse arises logically from nature’s most innocuous-seeming feature: empty space. Specifically, the seed ...

If quantum field theory is right about vacuum energy, our universe shouldn't exist. If vacuum energy really does have the enormous value predicted by quantum field theory then our gently expanding, ...

Could the collapse of a warp bubble light up our detectors long before humanity even builds one? What used to be the province ...
