New Measurements Confirm Faster-Than-Expected Universe Expansion
Recent astronomical studies have confirmed a discrepancy in the universe's expansion rate, known as the Hubble tension. A collaboration measured the Hubble constant at 73.50 kilometers per second per megaparsec with high precision. Separate research suggests dark energy may be we…
