Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

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) ...

For more than a century, physicists have been trying to reconcile the smooth geometry of gravity with the jittery ...

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 ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...

A RECENT GROUNDBREAKING EXPERIMENT in which anesthesia was administered to rats has convinced scientists that tiny structures in the rodents’ brains are responsible for the experience of consciousness ...

Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto itself.
