Before everything cooled down after the big bang!">get a better telescope>see it a bit better>now fast forward decades to today>get a really, really really good telescope>turns out it was just more galaxies>there was no cosmic soup from an early universe>all the data explaining the big bang, expansion, cosmic inflation is suddenly built on a misunderstandingoops lmfao
