The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a ...

But researchers still disagree widely on how best to describe the physical reality that lies behind the mathematics, as a ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side ...

It’s the weirdest thing: quantum theory works incredibly well in practice. It powers devices ranging from MRI machines to lasers and the very computer you’re reading this on. But even after 100 years, ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

It doesn’t, of course. Quantum theory represents the ultimate outcome of superior logical reasoning, arriving at truths that could never be discovered merely by observing the visible world.

Quantum theory equation is far from unacceptable. Published 19 May 2021. From Peter Holness, Hertford, UK . Regarding Brian Reffin Smith’s letter reducing to absurdity the equat ...

Quantum mechanics isn’t sufficient to explain the Universe; for that, quantum field theory is needed. This is why. Schematic animation of a continuous beam of light being dispersed by a prism.

The trouble is that we can’t know for sure. The best support we have for this hypothetical scenario comes from solving complex equations in quantum field theory, which require huge approximations.
