Dark Matter and the Large Structure of the Universe

Our simulations predict you should have like a really hardcore of dark matter. But what we see in our telescopes is not the same thing. We see like a flatter distribution It doesn't like get as peaky towards the core. The density of dark matter at the very heart of these dwarf galaxies is lower Than what we expect in astronomy. And so that's a bit of a puzzle right? Well, there's lots of really fun ideas this is a big crack and sort of the success of dark matter in explaining the large structure of the universe.
