Detecting the gravitational wave memory effect from core-collapse supernovae
Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing gravitational wave will permanently change the distan.....»»

How do you make a kilogram? Gravity can provide new answers
Claus Lämmerzahl, Professor of Gravitational Physics at the University of Bremen, and Dr. Sebastian Ulbricht, scientist at the Natural Metrology Institute, have proposed in a new article that gravity could be the basis for the quantum-physical reali.....»»
Do the fastest-spinning pulsars contain quark matter?
Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse. Electrons are squeezed together with protons so that the co.....»»
