On the definition of infinity:

Infinity is not a really long time, or a very far distance, or a very large mass... infinity is a way of describing existence. There are two forms of infinity that I accept, limited and unlimited.   A cycle can be described as limited infinity for those trapped within it.  This form of infinity conforms with the Einstein conception of curved space-time. Unlimited infinity is bounded only by experience, existence, and imagination.  Infinity is a negative limit. My mathematical definition of infinity is the square root of negative 1. ----------
