For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

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

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

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.

Gravity, long the sovereign force in the cosmic hierarchy, may be little more than a statistical side effect a byproduct of entropy, not a fundamental interaction. That is the provocative assertion ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...
