      Our universe is the coolest one! It has amazing things in it – look at all the galaxies which are different shapes and size, and crash into each other. And all the amazing exoplanets we are finding, which are so different to the ones in our solar system. But if there are other universes, too, they could be so totally different that they would just blow our minds, so it would be great to find out if they are there and more about them.

      Real ones: our own of course! However, technically the coolest Universes are those many “failed” Universes made in super-computers where we realise that without dark matter for example, no stars would ever be formed and we wouldn’t exist, and the Universe would just be completely cold, dark and empty! Not really “cool”, but certainly incredibly cold!
