3) A term encompassing all space and time (completely devoid of any numeric value).
I believe that answer 3) is the correct. A common example used in our argument is the half-distance paradox. If I walk halfway to point 'A', and half that distance, and half that distance, etc.... I believe I will eventually make it if I take an infinite number of steps. 1/2^n = zero in my books. I reasoned that the only way this is possible is if infinity can be defined as 3).
What do you guys think? Remember to think in 11-dimensional terms...

Sorry if someone mentioned this already but there are min maxes to energy (and therefore matter and all that exists). Plank's constant to speed of light. In other words, your example is flawed. There is a minimum distance one can travel. So it would not take infinity to get there.
I think infinity as a theory/practical math application exists of course. But no, to us infinity does not really exist. Everything, everywhere dies.
