I found this comment by Torbjorn very interesting here. "But Totani deviate from the consensus and thus consider us rare in the universe. Along that line of analysis, cosmologists think not since we discovered inflation. Eternal inflation, which is what we see, naturally makes infinite many universes, each with its own physics. Very few – roughly 1 out of 10^120 – are habitable since star or even atoms demand physics in a narrow range. "
My observation, *which is what we see*. To get around a rare Earth and universe we live in today, cosmology uses inflation and multiverse doctrine. Reports I have show the multiverse could contain 1E+500 different universes, and now I see 1E+120 universes in the multiverse may be habitable. Okay folks, here was consensus cosmology thinking in 1948, a lesson from the past.
“Nineteen years after Edwin Hubble’s discovery that the galaxies seem to be running away from one another at fabulously high speeds, the picture presented by the expanding universe theory—which assumes that in its original state all matter was squeezed together in one solid mass of extremely high density and temperature—gives us the right conditions for building up all the known elements in the periodic system. According to calculations, the formation of elements must have started five minutes after the maximum compression of the universe. It was fully accomplished, in all essentials, about 10 minutes later.” —Scientific American, July 1948
Apparently the cosmology department underwent some serious new math development to work with new observations since 1948, but both use QM and GR to explain the expanding universe. At the moment, I am not aware that any telescope on Earth recorded and observed 1E+120, potential habitable universes with stars in them. The Big Bang model shows CMBR redshift where z >= 1000, thus the universe is limited to about 46 billion light years radius as cosmology calculators show,
https://ned.ipac.caltech.edu/help/cosmology_calc.html, just plug in z=1000 and use the default settings for flat universe calculations.
Presently very remote objects have redshifts near 12.0 recorded by telescope spectra like GN-z11. Telescopes operating on Earth (or space) do not *see* what inflation claims in this discussion, i.e. there are other universes and stars that statistically according to multiverse thinking, could be habitable. Galileo argued against the geocentric astronomy using the telescope. Others using the telescope confirmed that the Galilean moons were there, and moved around Jupiter so supported what Galileo presented. I use my telescopes and can confirm that the Galilean moons are there and move around Jupiter today, some 400 years later. Presently we have confirmed 4255 exoplanets now,
The Extrasolar Planets Encyclopaedia
No exoplanets on this list are documented showing life is there (presently). Telescopes do not show other universe that could be habitable with other stars too that could support life as we see here on Earth. This is what we do see today using science and the scientific method, rooted in observations, testing, and falsifying claims.
