The latest cosmology indicates - uh, no. We actually shouldn't exist.
Fortunately, there's an easy explanation - experimental error. The B-mode polarisation that supposedly proves the Big Bang isn't actually that strong as proof. It could also be caused by, well, intergalactic dust.
Either that, or we're barking up a very wrong tree (I am tempted to insert Yggdrassil jokes here). Most likely? Most likely this is another case of "the more we know, the more remains to discover."
Or there's some other explanation for why the math says the universe should have been destroyed almost immediately.
Cosmology. I love it, but sometimes it gives me a headache. Read why we shouldn't exist here.
