Infinity is something so massive that the conventional laws of both mathmatics and physics go haywire. For example: If an object had infinite mass or volume, it destroy the entire universe and bend/shatter our 4-dimension plane of space-time. It could create even more Infinities, like an infinitly-looping time-space wormhole or who knows what else!
Technically, neither Zero nor Infinity are real numbers. They both defy the laws of physics & mathmatics. Try dividing Zero or Infinity and see what you come up with:
Infinity divided by Infinity = Infinity!?
One divided by Zero = Universe Implodes?
Infinity divided by Zero = MADNESS!
