A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

Scientists have proposed a bold new explanation for how the universe began, suggesting the Big Bang’s rapid expansion may have emerged naturally from the laws of quantum gravity. Credit: Shutterstock ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...

Leggett later switched to theoretical condensed-matter physics, and rapidly made the subject of macroscopic quantum phenomena his own. Only eight years after his PhD, he created a remarkably intuitive ...

Scientists from the University of Waterloo and the Perimeter institute have discovered a new cosmological model, challenging the traditional understanding of the Big Bang origin. The new ...

A mind-bending theory called quantum immortality suggests that your consciousness shifts to parallel universes after you die.

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

Charles H. Bennett and Gilles Brassard, winners of this year’s Turing Award, spent their lives touting the advantages of the ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the ...

Researchers at the California Institute of Technology theorize that a functional quantum computer may require far fewer ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...
