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 ...

Physicists explain the controversial theory that dark energy comes from supermassive black holes—and what it means for Einstein’s theory of general relativity.

Researchers at the Massachusetts Institute of Technology (MIT) have observed and captured images of a rare “edge state” in ultracold atoms. Using these findings, they can learn to achieve and ...

Imagine building a power plant around the Sun - that is the basic idea behind a Dyson sphere, a hypothetical megastructure designed to capture the full energy output of a star. First proposed in ...

The Final Barrier to (Nearly) Infinite Energy. Season 10 Episode 34 ... Slam hydrogen nuclei together into helium and a bit of the original mass is converted into energy.

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.
