conceptualizing infinity

[IcSilk]

What a perfect forum to share a concept that has been amazing my mind for the past month. Im sure some will find this as intriguing as I do and of course others will not give a patsy.
Im taking this course at school on Physics Theory, and obviously no course on physics theory is thorough without profound class discussion on general relativity.
During a lecture concerned with the topology and size of the universe we got into the contents of finite variance and infinity. Everyone knows what infinity is - neverending and possibly boundless - but like myself previous to this class I think that most people fail to grasp the actual concept of NEVERending. For those like myself who haven't really appreciated the concept of infinity objectively, mull this over in your minds for a bit:

In an infinite universe of finite variance (countable number of particles and atoms) there is no other option but that everything has an exact copy or doppelganger of itself. So there is not only one other exact copy of Franco (me) in the universe but an infinite number of them traversing the cosmos, habitating on an exact replica of this planet, sitting on exactly the same couch, punching keys on the exact same laptop. We may be just copies of the originals, ourselves.

That this is a necessary truth, as long as the two concepts of an infinite universe and finite variance hold true, is quite awe-inspiring.

That a countable number of items can only be put together in so many combinations before the same combinations have to start repeating themselves and that in an infinite medium these combos would be repeated an infinite number of times, really bangs home just how intense a word infinity really is.


Its great to have the perfect forum to vent minded concepts, lol
