Where Infinity goes wrong :
Let us say that the following series has an infinite number of terms:
S = 1 - 1 + 1 - 1 +1 - 1 ..... and so on forever
Now there are different ways we can group these :
S = (1-1) + (1-1) + (1-1) + .... and so on
therefore S = 0 + 0 + 0 + 0 .....
so S = 0
but there is another way we can group these numbers in the series:
S = 1 + (-1 +1) + (-1 +1) + (-1 + 1) + ........... and so on
In this case S = 1 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + ......... and so on
therefore S = 1
Therefore in this series, with infinite terms, 0 = 1
I got this example from a book, and I thought it was a good example of when Infinity can cause unecessary problems in Math.
But we also know infinity causes problems in Physics, e.g when we say space time can have infinite curvature. This runs us into a singularity.
What do you think, is infinity really necessary, or is it a concept that should be discarded ?

Some scientists are thinking that you loop back around on the other side of the universe. Of course just thinking about the extreme vastness of it all makes me feel so insignificant it makes me wanna cry.

You have to forgive albie, he apparently hasn't learned of quantum mechanic's yet.
The two thing's people have the most trouble grasping.. Infinity and nothingness. We live in a finite space, all our experience's deal with the finite, so obviously we think of thing's to be finite. We also live in something, so it's hard to imagine a nothingness. Surely we can't exist in nothingness if we live in something, right? Well, maybe the universe does exist in nothingness, we don't know for sure what the condition's are outside our sphere of existance. Perhap's that nothingness is also like our vaccuum in space, appear's to be nothing there, but measure it at the quantum scale and you see a sea of virtual particals popping in and out of existance. I honestly don't have a problem with nothingness nor infinity as most people do. I think it's rather cool.

What hapens when you try to pass the end?, is there a big brick wall saying the end of universe nothing beyond just dark and nothing?well i can go in the dark and walk and i'll be heading away from the universe, simply because i'm heading away means that i'm moving, if i'm moving that means it's something.
To put an end to infinity it would require a wall or some sort, i dont know
if some of you noticed it playing a 3d video game and when you try to go off
map you cant, it jsut a puzzle, we are not even bacteria compared to the whole universe.
I think infinity means just darknes nothing, no matter no nothing, is it possible to move in darknes?that would be the question.

Quantum mechanics is mathematical THEORY. Hence fiction.

Ok, have'nt read all the posts, read the first 10, but since I'm respondinf to the first, I don't have a need to read further, plus I feel a bit queasy, so I'm definately not gonna make it worse by reading more posts that make me think.
Ok, now I scientifically believe in infinity, I don't see how the universe or anything could exist without it, thats with my personal beliefs, which deal with many infinites, aside.
I mean for example, if something is finite in size, than there has to be something outside of that, and that go's on and on and on, you can't say, well theres somethig that the end point, for that it would have to be finite, and therefore have to be something outside it, or it would have to be infinately large.
