A sign-changing dark energy model moves Hubble estimates closer, but rigorous tests show the cosmological tension remains.
SpaceDark energy reversal cannot close the universe’s expansion gap
CPT symmetry states that the laws of physics stay the same when electric charge, spatial coordinates, and the direction of time are all reversed simultaneously.
