Ping!....................
I know it’s probably something I would not understand, but when Scientists say in an article, they are peering back into the origins of the Universe with the JWST, I wonder what happens in 20 or more years when another telescope is out there which is 100 times more powerful than the JWST and can see even further back in time, meaning how does anyone know when the end of the universe has been reached.
Once JWST became operational, there is no longer any mention of light shift/bending from gravitational waves.
OK... so the galaxy’s spectra are what you’d expect from a galaxy that’s way beyond the farthest known galaxy... but the spectra could also be skewed by fact that it’s simply spinning away from us extra-fast because it’s spinning around a parent galaxy? Couldn’t add THAT much extra speed? And what does a huge number of newborn stars have to do with redshift?
How do I know it’s not just a picture of a salami slice?
How is it that the redshift is ambiguous? I thought the spectral signature enabled an unambiguous measure of the redshift.
