To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

A new theory could resolve longstanding tensions in mutually exclusive ideas about physics.

A new study just added an interesting twist to the complicated history of the physics theory.

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

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.

A chance meeting during a dip in the ocean was the first step on the road to quantum information science.

Well, around a similar time, the American Physical Society (APS) invited researchers and science enthusiasts to chime in on ...

The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of science is under construction that centres conscious experience – and might ...

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by ...
