Timekeeping theory combines quantum clocks and Einstein’s relativity

IMAGE: Quantum mechanics allows for a clock to move as if it were simultaneously traveling at two different speeds. New research finds that this leads to a correction in atomic clocks… view more  Credit: Petra Korlevic HANOVER, N.H. – October 23, 2020 – A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision […]

Einstein’s theory of relativity, critical for GPS, seen in distant stars

The intriguing system known as 4U 1916-053 contains two stars in a remarkably close orbit. One is the core of a star that has had its outer layers stripped away, leaving a star that is much denser than the Sun. The other is a neutron star, an even denser object created when a massive star […]
