Missing link in metal physics explains Earth's magnetic field

Earth's magnetic field is crucial for our existence, as it shields the life on our planet's surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means ...

Quantum computer as detector shows space is not squeezed

Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions - that it's not squeezed in one direction relative ...
