Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

This interaction could help explain both why quantum processes can occur within environments like the brain and why we lose consciousness under anesthesia.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests. When you purchase through links on our site, ...

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 ...
