Katie MackHave you heard about JWST seeing galaxies that shouldn’t exist? There’s more to that story!
My latest for BBC Science Focus: https://www.sciencefocus.com/comment/james-webb-space-telescope-ancient-galaxies
Nick AppleyardNoting the caveats about the observations, if this does mess up the cosmological age/distance curve then what are the implications?
Is dark energy then trashed, for example?
@nick_appleyard Nah nothing like that. At worst, it would require altering the expansion rate in the early universe somehow
@AstroKatie or maybe it’s a Hubble Bubble?
No idea whether that explains anything, I just enjoyed typing it.
