Wigner's Friend is a paradox in quantum physics that describes the states of two people: one conducts an experiment, and the other observes that first person. Traditionally, the thought experiment ...

An example of a light cone, the three-dimensional surface of all possible light rays arriving at and departing from a point in spacetime. The more you move through space, the less you move through ...

By exploring positive geometry, mathematicians are revealing hidden shapes that may unify particle physics and cosmology, ...

Light is everywhere,it illuminates our world, enables vision, and travels across galaxies. But what is light, really? Is it a ...

For example, a limitation that was subtle and had to be corrected was the neutrino mass. This particle is so light that scientists were unsure if it even had mass.

In the current approach to physics, some laws already have this counterfactual structure — the conservation of energy, for example, is the statement that it is impossible to have a perpetual motion ...

But look, if we get into all that, we're going to go real deep on particle physics and it'll explode our brains. The neutrino is unique because it has a vanishingly small mass and no electrical ...

Artificial intelligence software is designing novel experimental protocols that improve upon the work of human physicists, although the humans are still “doing a lot of baby-sitting.” ...
