Watch “Why the Universe is quite disappointing really – Episode 5” on YouTube
Episode 5, in which I explain using a golf ball just how empty the Universe is. It is so empty, in fact, that even the crowded places are very empty. And as for the empty places, they’re practically nothing.

My favourite illustraion of the emptiness: The entire observable universe, if compressed to the density of nuclear matter, would fit comfortably within the solar system.
