Helio replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.I assume you discount the BBT claim of only H and He in the early period. This prediction was found in the 1940s (Gamow and Alpher) and... -
Helio replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.In the early universe, I'm unsure if black hole mergers contribute much, even if they merge with neutron stars. Are there models that...

Helio replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.Only Pop III stars would produce the elements for normal stars. BHs only contribute concentrated mass, AFAIK, assuming they were...

Helio et al, I think Harry Costas has a point in post #2, "For some reason they are trying to fit the narrative to the BBT." Population... -

Space.com reported, “This previous record galaxy has a redshift of z =14.32, while MoM z14 has a redshift of z = 14.44.” My note, 3D...

Helio replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.According to BBT, the universe was necessarily H and He only, discounting tiny amounts of Li and perhaps Be. It took lots of work to...

Helio replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.C, N, O and other elements are produced by massive supernovae. Pop III stars were very likely extremely massive and had very, very...

Helio replied to the thread Cosmic miracle!' James Webb Space Telescope discovers the earliest galaxy ever seen.The primary argument for building the JWST was to get us to a farther horizon and closer to the first stars. The news of such an early...

This "IF" is a big one. "If there were a lot more Earths, we wouldn't be so special". This is true, but not useful.

For us amateurs without academic contacts we can sometimes succeed by looking at old, available, data in new ways. AI comes to mind. Why...
