The idea that empty space is truly empty has been quietly dying for decades, but new measurements of particle spin are now forcing the issue. By tracking how tiny fragments of matter emerge with ...

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 ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum dimensions at the same time, and they can make it do the trick on demand. The result ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...
