Physicists have measured an atom's 'neutron skin' for the first time
Gravitational-wave scientists propose new method to refine the Hubble Constant - the expansion and age of the universe - a simple and novel method to bring the accuracy of the Hubble constant measurements down to 2% using a single observation of a pair of merging neutron stars.
Black Hole-Neutron Star Collisions Could Finally Settle the Different Measurements Over the Expansion Rate of the Universe
