Everything you might want to know about infinity - in history and all the way to today's cutting-edge science.
Infinity is surely the strangest idea that humans have everthought.Where did it come from and what is it telling us about ourUniverse?Can there actually be infinities? Or is infinity just a labelforsomething that is never reached, no matter how long you go oncounting?Are infinities like numbers, with some bigger than others, andoneinfinity at the top, bigger than all the rest?
