In current quantum field theory, causality is typically defined by the vanishing of field commutators for spacelike separations. Two researchers at the University of Massachusetts and Universidade Federal Rural in Rio de ...
It's no secret that black holes are objects to be avoided, were you to plot yourself a trip across the galaxy. Get too close to one and you'd find your ship hopelessly caught sliding down a gravitational slippery slope toward ...

A team of researchers from Universidad de Zaragoza, King's College London and the Institute of Astronomy in the U.K. has found that a "dark matter hurricane" passing through our solar system offers a better than usual chance ...
A RUDN University physicist has developed a formula for calculating Hawking radiation on the event horizon of a black hole, which allows physicists to determine how this radiation would be changed with quantum corrections ...
