SUMMARY

The discussion centers on the implications of the Cosmic Microwave Background (CMB) raising the zero, specifically referencing Roger Penrose's hypothesis. As the CMB redshift approaches zero, the universe's mass will predominantly be contained in black holes, which will eventually evaporate due to Hawking radiation. This process leads to a universe that transitions from being entirely radiation-dominated to a state devoid of particles with rest mass, ultimately resulting in a radiation-only universe.

PREREQUISITES
  • Understanding of Cosmic Microwave Background (CMB) concepts
  • Familiarity with black hole physics and Hawking radiation
  • Knowledge of redshift and its implications in cosmology
  • Basic grasp of the universe's evolution theories
NEXT STEPS
  • Research Roger Penrose's theories on the universe's evolution
  • Study the mechanics of Hawking radiation and its effects on black holes
  • Explore the implications of redshift in cosmological models
  • Investigate the concept of radiation-dominated universes in astrophysics
USEFUL FOR

Astronomers, cosmologists, theoretical physicists, and anyone interested in the long-term fate of the universe and the behavior of black holes.

The zero will implode.

One suggestion by Penrose is that by the time the redshift of the CMB approaches zero, most of the mass of universe will be locked up in numerous black holes, but because by then the radiation from black holes exceeds the energy absorbed from the CMB the black holes evaporate away to leave a universe that is all radiation, with no particles with rest mass. He likes the symmetry of a universe that starts out as all radiation and ends up as all radiation.
 


These posts are not making sense at the moment.

Are you asking: "What happens when the redshift of the CMB approaches infinity, in which case the energy of the individual CMB photons approach zero?"

In the inconceivable future the matter would end up locked in BHs that after eons of time will evaporate through Hawking radiation leaving behind an unstable eternity.

I like Fluxman's answer best.
