JWST Observation Challenges Cosmological Models: 60% of Early Universe Galaxies Rotate Clockwise

The James Webb Space Telescope (JWST) has observed that 60% of early universe galaxies rotate clockwise, challenging cosmological models and suggesting either a rotating universe within a black hole or a need for recalibrating cosmic distances due to the Doppler effect.
