A state of matter last seen just after the Big Bang may exist inside neutron stars -- and scientists think they can prove it
By breaking down the problem into separate regions of varying gravitational strength and combining approximate solutions, researchers were able to derive a solution describing all the oscillatory modes of a neutron star's interior and how they are imprinted on the frequency of gravitational waves.

How fast is the universe actually expanding? Ripples in spacetime could finally solve 'Hubble tension'
By analyzing the gravitational wave background from distant black hole collisions, researchers hope to develop a method that can independently measure the Hubble constant and potentially end the longstanding Hubble tension.
