Physics51¶¯Âþs created a ‘giant quantum vortex’ that mimics a black hole Black holes can be difficult to study, so researchers have made a powerful quantum vortex in a tank of superfluid helium that acts as a simulation of a black hole 51¶¯Âþ
PhysicsLasers fired at crystals could uncover quantum nature of the vacuum Ultra-short laser pulses may allow us to measure entanglement in a way that answers questions about the quantum nature of the vacuum 51¶¯Âþ
