The Hubble Tension is one of the great mysteries of cosmology. Solving it might require a fundamental change in how we understand the universe - but scientists have to prove it actually exists first. A new paper from a collective of cosmologist researchers known as the TDCOSMO Collaboration adds further fuel to that first with updated measurements of the “Late Universe” measurement of the Hubble Constant using gravitational lenses of quasars, which shows that the Tension might exist after all.
