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,

Scientists considered a theory of gravity where matter curves space more strongly. In this model, rotation prevents the wormhole from collapsing, eliminating the need for exotic matter. Since almost all cosmic bodies rotate, such tunnels could form naturally. They would be betrayed by a double shado
