Infinity vs Finiteness

Talking to someone very close to me I was told that they cannot cope with the ideas of finiteness vs infinity. The fact that something is either completely closed off with a beginning and an end or the idea that it is all open - there is no end to it, it's beyond space and time, freaks them out. Not only does it freak them out but causes them to hyperventilate and shut down.
To me this idea is astonishing, not only because so many questions in life are about mortality versus afterlife and how big space is, but also because I don't find either of those ideas worrying. To me, personally, I find it comforting to know that both sides could exist.

The idea of infinity is one that is as old as the thinkers; gods, afterlife, heaven, hell and even purgatory are all ideas of an eternal afterlife or, in case of the gods, eternal life. The idea that after we die there is somewhere without all earthly issues and worries is fantastic, eternal life in a way that we cannot even begin to fathom. We guess, we assume, but none of us really have a clue as to what would really be waiting for us on the other side. Personally I like to believe in the What Dreams May Come version of heaven, I think it's very beautiful and rather fantastic. If it exists, that is how I believe it would be, something personal, where you can be how and what you wish to be.
Personally I do not think a hell would truly exist if God was one that was truly benevolent, he would not be able to put his creations through such agony, surely. I do believe that purgatory exists, no fire, no joy just never-ending numbness.

However, if neither of those exist I don't have a problem with it. The idea that when we die we are completely done, finished, worm food is also something I find comforting. It gives me a feeling of satisfaction thinking about it that way, if we die we are dead. There is nothing left to worry about and there is no more of you. There is nothingness.
Certainly, it is strange to think about in a way that you will never again know that you have lived on this earth, you are in a way completely erased except for in the memories of the people still alive, in the stories they tell. Slowly all you will be, unless you were a mover or a shaker, is a name on a family tree - a distant relative long long ago. And that is satisfying. There is no wondering whether or not you will have to go through another life for all eternity, there is just the end.

Let me know your thoughts on this, I'd love to hear what you all think. Leave a comment or e-mail Isaab@live.nl
