For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges.

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead ...

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.

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

What happens when the two most successful theories in science completely disagree? You get quantum gravity—a chaotic battlefield where time might not exist, and gravity behaves like a quantum ghost.

Returning to the quantum, by 1919, six years before the invention of quantum mechanics and the uncertainty principle, Einstein recognizes that there might be a problem with the classical notion of ...

As Professor Oppenheim puts it, "Quantum theory and Einstein's theory of general relativity are mathematically incompatible ...

As Professor Oppenheim puts it, "Quantum theory and Einstein's theory of general relativity are mathematically incompatible with each other, so it's important to understand how this contradiction ...
