They have been downgraded from trillions to mere hundreds of billions, according to a new estimate:

Galaxies are likely “numbering only in the hundreds of billions rather than the previously reported two trillion galaxies,” NASA said in a statement. One of the project’s lead researchers said that scientists reviewing New Horizon’s data “simply don’t see the light from two trillion galaxies.”

Daniel Payne, “Experts say number of galaxies in universe may be significantly less than earlier estimate” at Nation

Here’s the statement.

Hmmm. Reminds some of us of what real estate agents like to say when they are selling waterfront: “Waterfront? Well, they are not making any more of it.”

It is 'worse' (or better, depending how one looks at it) than that. As in SPIRAL we find the entire universe approximates the approx. sphere that is the visible universe, with a max LY radius of 4B. SPIRAL being over 150T times a more reasonable claim than the current SCM-LCDM consensus. reference the YeC Moshe Emes series for Torah and science alignment volume II 'SPIRAL' cosmological redshift hypothesis and model.Pearlman

Einstein's cosmological constant was based on a static universe. It should not work if the big bang theory is an accurate assessment of the universe followed the supposed bang. His cosmological constant does work, which means there is something else that happened that big bang does not address.BobRyan

Vaguely related to Olber's Paradox. One of the reasons that we know that the Universe is neither static nor infinite.Latemarch

More details: >>How dark does space get? If you get away from city lights and look up, the sky between the stars appears very dark indeed. Above the Earth’s atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn’t absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies . . . . New measurements of that weak background glow show that the unseen galaxies are less plentiful than some theoretical studies suggested, numbering only in the hundreds of billions rather than the previously reported two trillion galaxies. “It’s an important number to know – how many galaxies are there?” said Marc Postman of the Space Telescope Science Institute in Baltimore, Maryland, a lead author on the study. “We simply don’t see the light from two trillion galaxies.” The earlier estimate was extrapolated from very deep sky observations by NASA’s Hubble Space Telescope. It relied on mathematical models to estimate how many galaxies were too small and faint for Hubble to see. That team concluded that 90% of the galaxies in the universe were beyond Hubble’s ability to detect in visible light. The new findings, which relied on measurements from NASA’s distant New Horizons mission, suggest a much more modest number, consistent with older Hubble data. “Take all the galaxies Hubble can see, double that number, and that’s what we see – but nothing more,” said Tod Lauer of NSF’s NOIRLab, a lead author on the study.>> Shrug . . .kairosfocus
