Infinity...

May be, I am wrong..

1. There are NO existing physical infinities in this universe. (Q stays if universe is infinite or not :-))
2. Infinities can potentially exist, even physically.
3. Logical infinities are great tools to create mathematical model of universe.
4. For pure maths, infinities can and do exist.
5. infinite is equivalent to "too large for a context" (though your modelling assumptions will affect) if you use infinity to model something physical.
