When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden ...

Researchers at the LIGO gravitational wave observatory used a new technique called frequency-dependent squeezing to boost weak signals above quantum noise. When you purchase through links on our ...

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.

The principle of wave-particle duality is crucial in quantum physics, highlighting the dual nature of light and matter and ...

Quantum gravity research aims to merge general relativity and quantum mechanics, potentially reshaping our understanding of the universe's fundamental laws.

Once a gravitational wave passes through this massive detector, each oh-so-subtle vibration detected by a change in energy level would be a graviton. Related Story A 12-Mile Dead Star Turns ...

There's a 100-year-old conundrum in physics that we're still yet to untangle, and it has to do with the very nature of space-time itself.
