A new theory proposed by researchers at the Stevens Institute of Technology, Colorado State ...

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight and true, and all we can do is go ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always posed a problem. Physics can describe a great deal about the universe ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades in the making, could help physicists probe the relationship between quantum ...

Quantum key distribution (QKD) has been positioned as a physics-based method of securing encryption keys that cannot be ...
