Imagine if we could collect the energy out of thin air. And I mean it quite literally.You know how you were taught that a ...

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 ...

Amind-bogglingly huge buildup of "vacuum energy," which would occur injust milliseconds, could lead the stellar remnants known as neutron stars toinstantly collapse or explode, scientists now suggest.

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 the late 1990s, two teams of astronomers were out to settle a score. Cosmologists had been at odds for over a decade in their quest to measure the total amount of matter and energy in the universe.

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 ...

Researchers at the University of Copenhagen's Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. The new data shows that ...

Vacuum is not synonymous with nothing, at least for physicists. They claim that even seemingly empty space still contains some form of energy that fluctuates constantly, like the small waves that ...

Dark energy and I came of age together. In 1998, two competing groups of astronomers discovered that the expansion of the universe was accelerating; the same year, I graduated from college with a ...
