How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...

Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every ...

Maria Violaris works on quantum foundations as an academic visitor at the University of Oxford, UK, and on quantum computing at Oxford Quantum Circuits, Reading, UK. Norma G. Sanchez, is the founder ...

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 small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is. Reading time 3 minutes The entire spiel of ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Does quantum mechanics allow the future to retroactively influence the past or not? Does quantum mechanics allow the future to retroactively influence the past, as in the infamous delayed choice ...

In an effort to solve the riddle of why we have subjective conciousness, scientists have develop myriad theories, including ones involving the quantum realm. A new theory suggests that consciousness ...
