Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...

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 ...

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.

Reliably quantifying and characterizing the quantum states of various systems is highly advantageous for both quantum physics ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Physicists talk about quantum physics, quantum mechanics, quantum entanglement, quantum computing but what if we could, by analogy, apply the quantum physics theory to our mind and talk about quantum ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...
