The Universe doesn't have a physical centre for the reasons I gave in my previous post. Neither does the Universe have an edge, the implications for that would be expansion into existing space. In other words metric expansion of space wouldn't occur and we wouldn't be able to explain Hubble's Law or the mechanism of cosmological redshift.

I always though maths was used to describe what we see not what we can't see. I suppose I got it all wrong. I watched the BBC - "Dangerous Knowledge" program and I suppose they died from trying to work out what they couldn't see, although they did live in difficult times. So yes we need to be careful with math.

These guys worked in the field of pure mathematics. Pure mathematicians consider themselves artists, and probably had all the attributes of artistic temperment.

Not surprising some of them went the way they did.
Others went in more spectacular ways.
This kid died at the age of twenty, his ideas in mathematics were so advanced they were used in physics 120 years after his death.
