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

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

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

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 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 ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...

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