In the world of next-generation energy, researchers are taking a leap beyond chemistry into the strange rules of quantum mechanics. A new type of battery, known as a quantum battery, is no longer just ...

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally dreamed up to help untangle paradoxes in quantum theory and relativity.

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?

Findings back Einstein’s theory and raises new questions on universe’s expansion The Dark Energy Spectroscopic Instrument at Kitt Peak National Observatory (above) in Arizona, which can ...

Scientists have unveiled a new theory that attempts to unify the mysterious worlds of quantum physics and general relativity. This new theory could change the way we understand the cosmos, black ...

• General relativity extends special relativity by incorporating gravitational effects, describing how mass and energy curve spacetime, influencing the structure of the universe.

Physicists suggest tachyons can be reconciled with the special theory of relativity by University of Warsaw Editors' notes Credit: Pixabay/CC0 Public Domain ...

New warp drive concept does twist space, doesn’t move us very fast While it won't make a useful spaceship engine, it may tell us more about relativity.

Large High Altitude Air Shower Observatory in western China helps team test Einstein’s theory, finding no evidence that particles’ speed changes depending on energy.

In 1905 Albert Einstein wrote four groundbreaking papers on quantum theory and relativity. It became known as Einstein’s annus mirabilis or wonderous year.
