JWST early Universe observations and {\Lambda}CDM cosmology

Understand

Deep space observations of the James Webb Space Telescope (JWST) have revealed that the structure and masses of very early Universe galaxies at high redshifts (z~15), existing at ~0.3 Gyr after the BigBang, maybe as evolved as the galaxies in existence for ~10 Gyr.

• The JWST findings are thus in strong tension with the ${\Lambda}$CDM cosmological model.
• While tired light (TL) models have been shown to comply with the JWST angular galaxy size data, they cannot satisfactorily explain isotropy of the cosmic microwave background (CMB) observations or fit the supernovae distance modulus vs.
• redshift data well.
