Cosmic Microwave Background — Observation and Interpretation

1. Standard Definition

In standard cosmology, the Cosmic Microwave Background (CMB) is the faint thermal radiation left over from the time when the universe cooled enough for electrons and protons to form neutral hydrogen.
At that moment (≈ 380 000 years after the Big Bang, at ≈ 3000 K), photons ceased to scatter continuously and began to travel freely.
The resulting radiation, red-shifted by the ongoing expansion, reaches us today as a 2.725 K blackbody in the microwave band.

Meaning of red shift

When does a red-shifted photon dissolve into the “vacuum”?

Question.
If a photon’s wavelength keeps increasing with cosmic red-shift, at what point does it become indistinguishable from the background vacuum fluctuations?
In other words: when does a photon “drown” in the quantum sea of space itself?
