Oh math--I do not know what i am talking about, but-----

The idea of infinity has always intrigued me. I guess it started with the idea that, as good Christians, we would go to heaven and live forever in happiness. Now the thought of happiness did not bother me. And the thought of hell did not necessarily scare me much. But the thought of eternity was something I just could not deal with! This topic came up again later in math. "As the answer approaches infinity....", the teacher said as if she was talking about an interesting topic like love or lunch.. And then she went on to show that mathematicians had used this concept in math equations. I was dumbfounded; a situation that I find myself in often,but intrigued to no end. And this is one of those "no ends".
Given that infinity can be used in certain math equations with the realization that the answer could not change much because the numbers used in part of the equations would be so small or so big as to not effect a difference.But this has to also mean that the distance between the larger numbers, or the quantity between the numbers must be different than the distance or quantity between more serviceable numbers. If this is true, then a standard number line cannot be a straight line, but must bend slightly at very large or very small numbers. (I do not know whose theorem this belongs too; I steal thoughts and anything that's not tied down.
And you must admit this idea is a thought and is definitely not tied down!)
Taking this one step further, would it not be just as evident that these numbers would eventually become so small as to become negative numbers, forcing both ends of a standard number line below the reference line.
I imagine the standard number line as being an extremely stretched out bell shaped curve, which eventually
mirrors itself along the x reference line. To travel along the number line, as any equation must do, it eventually has to return to its original starting point. In our world, numbers can be negative or positive, but in reality, our world is only our time. Time, as I see it, causes our equations to work. They would not be functional in another time. This thought would also give credence to alternate universes. But for future generations, perhaps, different formulas for differing time will allow space travel and glimpses into different universes.
