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

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

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

Researchers say they've proven that the fundamental nature of reality simply cannot be simulated on any computer.

Explore the complex challenges of quantum gravity in this video, examining the evolution of gravity models and the necessity ...

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

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

“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 ...

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

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.

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 ...
