Entangled particles show correlations that look instant, yet no message can travel faster than light. Here is what the speed tests measured and why relativity is still safe.

2026 Nobel Prize in Physics: IceCube and Ghost Particles Explained
Francis Halzen won the 2026 Nobel Prize in Physics for IceCube, a cubic kilometre of Antarctic ice that catches neutrinos from space. This piece covers how the detector works, what it found, and where the quantum physics comes in.
Aharonov-Bohm Effect Explained: 1959 Theory to Oxford’s 2026 Result
A charged particle can be affected by a magnetic field that is zero everywhere along its path. Here is how that prediction from 1959 was tested in 1960 and 1986, extended to gravity in 2022, and simulated on Oxford’s hybrid trapped-ion quantum computer in 2026.
EPR Paradox Explained: From Einstein’s 1935 Doubt to the 2022 Nobel
In 1935 Einstein, Podolsky and Rosen argued that quantum mechanics must be incomplete. This guide covers their argument, the replies, Bell’s theorem, the 2015 loophole-free Bell test, the 2022 Nobel Prize and why entanglement cannot carry messages.
