Whatever these objects are they contain little or no dust as you'd expect because dust requires elements other than hydrogen and helium which need to be made in stars, but if we really are looking at an object that has a red shift of 25 then we're looking at something that existed before stars did. If confirmed that would be a pretty profound discovery, and about the only thing that could explain them are Primordial Black Holes created during the first nanosecond after the Big Bang.* *JWST Found Objects at Insane New Distances (Redshift of 25?!)* <https://www.youtube.com/watch?v=saL_1R1WitA&t=797s> -- You received this message because you are subscribed to the Google Groups "Everything List" group.
