The possibility that our entire universe merely exists inside a computer simulation is more than an idle science fiction ...

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) ...

Advanced simulations have been the subject of fiction from The Matrix to the season two episode of The Twilight Zone (2019), ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers aren’t so sure.

This idea was once thought to lie beyond the reach of scientific inquiry,” said physicist Mir Faizal of the University of British Columbia.

In their study, they identified what they called "Godelian truths", truths that cannot be defined by any algorithm or fixed ...

The answer to this question depends on how you think about quantum gravity, explains physicist Vlatko Vedral ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Scientists are exploring a revolutionary theory that suggests human consciousness might operate as a quantum hologram, ...

“We showed that if black hole morsels are created during mergers, they would produce a burst of high-energy gamma rays, with the delay time related to their mass,” Dr. Cacciapaglia said. “Our analysis ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...
