Is infinity even possible?

I've been wondering this even since I spoke with a friend of mine who studies philosophy at Stanford, and he brought up the subject of infinity and after hours of debating on the possibility of infinity in any sense of life or otherwise I've been wondering what you all would think on the subject. My belief is that infinity exists only in our dreams and after death because when we die we cannot watch time pass by thus creating this form of infinity, and when we dream our brains slow down speed up and stop our perception of time. Which leads to the infinitability of time because if the world were to end would this be the end of time itself? So before I dwell further in to this I want to know what your thoughts are on the things I brought up.

    time is but an invention of the human mind to sustain order in an ever changing world. without time chaos would consume our race things wouldnt get done and the whole working order of society would infinity is possible because time isnt whats needed for infinity. infinity means never ending in the form of counting numbers eternity is the reference to neverending time. if there was no time there would be no eternity but as long as numbers still existed infinity would still exist. +3 for a very thought provoking post

    u beat me 2 it and the way i see it what we call a set time like minutes and hours is just a way of representing time its self infinity will still exist because numbers are just a way of representing it not time its self

    agree with nightmare, unfortunately i'm too lazy to post my entire thought on this subject so i will leave you with this, "i like to kill things."

    space is endless so i think infinity is possible
    but I don't get what gust came out of your mouth right there

    but since we haven't explored farther than the Hubble telescope can see can we honesty say that space is endless or can we say that as far as we know space is an endless void

    if you didn't see the end of space then your argument is invalid

    Space isn't endless, it is just ever growing. If you were large enough to view all of space, you would see that it is not infinite.

    well all we see is the light from the farthest reaches correct? so it could be infinite and the light is just reaching us and that makes it seem to expand

    in mathematics it is. infact a parabola can go on forever.
    some answers to question can be expressed as "X<15 or X>18" meaning X = any number below 15 or above 18. which is infinite. showed on a graph as a "ray" at 15 and going down the number line, and a ray at 18 going up the number line. so that equasion, you can plug any number except any number 15-18 and it will work.

    also, lines are infinite, rays are infinite,

    if you think this only exists in theory. think about this question "how many numbers are there?"

    But numbers themselves only exist because of the way humans comprehend reality. Just because someone can draw a line with an arrow at the end of it, and says it is infinite, doesn't mean that it is. In mathamatics you can't divide by zero, but that doesn't really match up with the physical universe because numbers can't change from one kind of existance to another the way mass can turn into energy, and vise versa. Meaning that there really is no such thing as zero, even though it is a concept needed for mathamatics.

    But I can stay here and debate with that kind of logic forever, and the only thing that would actually differ between how we view our concepts in math and "real life" would be simply that: differences in concepts. Merely a different way of comprehending precisely the same thing. Which when you really think about it, all that "infinity" really is is a concept. Just like the number zero.

    This is a very interesting subject. I almost didn't post because of the fact that its so hard to try and describe/explain things via text. Or at least it is for me, so please bare with me.
    Infinity is by definition: The quality or condition of being infinite. Unbounded space, time, or quantity. An indefinitely large number or amount.
    You can tell by the definition that is rather hard to explain what is infinite, because of the fact that they use the word to define its self. The thought of something going on forever is incredibly hard to comprehend. Especially considering we know that our bodies do not. If you look at the different ideas for how the universe was created, the big bang, and the biblical creation. Both still hold true to that fact that everything just was. In the big bang, there was nothing but gases and small matter floating in nothingness, and then it exploded with such force as to expand space, and slowly creating all the planets and stars from the different matter and gases. Some say the universe is still expanding.. but if it's still expanding, wouldn�t that mean there is an end? Or would that simply prove the fact that the universe is never ending because of the fact that it is always expanding? Some believe that the universe will spring back after it has finished expanding, possible going back to nothingness again. Could this be the endless cycle that would consider space infinite? To me, truly understanding something that is infinite is almost impossible, but accepting it is not. I believe that no matter how the univers was created, it truly is infinite, in one way or another.

    in my opinion the real question is does infinity even matter. i say this because even if it's not real then it wouldn't change the fact that the human race has only a limited amount of time on this planet and the endless questions on subjects like this would take up far too much time for us as a whole to be bothered asking them and then getting answers. +3

    try dividing by zero. you'll get infinity.

    Infinity is a way of summing up what humans just don't have the mental capacity to understand. I think it is a bit of a waste of time trying to understand it because it just can't be done by the human brain. It's just beyond our understanding.

    And I am a strong believer that pretty much all of the fundamental laws of mathematics and physics are most likely wrong as if they were right then there would be no unanswerable questions such as this and many others.

    But that's just my opinion :P
