Scientists discovered that an object's own gravity destabilizes quantum superposition: the object quickly loses its fuzziness and ends up in one place. The collapse time is inversely proportional to mass—for heavy bodies it's almost instantaneous. The effect works even in free fall, explaining why l

The Universe is expanding, but measurements of the rate from early times and today disagree — this puzzle is called the Hubble tension. A new model introduces an invisible chameleon field that recently began nudging expansion further and adds invisible mass that holds galaxies together. Near Earth,
