is like a baking loaf of raisin bread
Stop me before I go further.. I mean can the self-inflicted irony be any deeper. Maybe.
"fundamental idea of cosmology is that everything looks the same in all directions" Okay, so no bang, because no center or edge to the bang as far as we can see.
"galaxy clusters ... held together by gravity" Oops, I think stepped in something
a "pillar of cosmology – the study of the history and fate of the entire universe – is that the universe is ‘isotropic,’ meaning the same in all directions," Hmm, are you sure...
"Astronomers generally agree that after the Big Bang, the cosmos has continuously expanded" See how that works. All the pillars and fundamental ideas are 100% contradicted completely. And not a single blink of the eye.
As if the Balloon analogy wasn't good enough, they've gone to baking bread. Some one show them the oven and how it works too.
