'Schrodinger's Galaxy Candidate' Is JWST's Latest Deep Space Puzzle to Solve...It could break our current understanding of the early universe, but there's a catch.

[Mr. K]

except that t-shirt is backwards.

It should be blue and say it’s red if you run fast enough

[Magnum44]

depends on which way you are running...

[Lazamataz]

meaning how does anyone know when the end of the universe has been reached.

There will be a line of cars and a Border Customs station.

[Nifster]

Good one

[Magnum44]

how does anyone know when the end of the universe has been reached

Thats no longer a real important question, since the 'end of the internet' was discovered right here on FR.

How is it that the redshift is ambiguous? I thought the spectral signature enabled an unambiguous measure of the redshift.

[Red Badger]

Suppose it as a young Galaxy or Globular Cluster with many proto stars that had not yet accreted enough mass to ignite the nuclear fusion fire.

They would be glowing in intense infra-red radiation, thus giving the appearance of red shift, but not really being red-shifted....................

[SunkenCiv]

Thanks Red Badger.

Some place to eat too

So what you’re saying is that they could see what color it is but not be able to discern precisely which elements were causing the glow? Because if they could see the spectral lines of a particular element, then it seems like they should be able to see what the spectral shift is.

Couldn’t a sophisticated enough device image infrared emitting clouds long before fusion reactions begin star light?
