Universe in a Neuron

On the top is a picture cosmologists developed which shows what the universe probably looks like if you could zoom all they way out.

I think it is pondering this kind of thing that drives mathematicians nuts and makes them want to drill their brains out.

Georg Cantor, for example, spent most of his life contemplating infinity. He developed the Continuum Hypothesis which classifies the different "levels" of infinitude. He also happened to spend the last 20 years of his life in an insane asylum.

I think that to focus one's thoughts so intently and for such a long time on a subject which is essentially completely removed from reality is to risk becoming detached from reality in general, and appearing insane to the "normal" world.
