جميل هو السؤال (خلاني أروح أقرأ و أبحث)
أعتقد الكثير من الأعضاء أعطوا الإجابات الصحيحة...
هذه قليل من البحث اللي سويته
There is no single answer to this, as infinity is not a number in the strictest sense.
Infinity is a "limit". It is something you can get closer and closer to, but you never
quite reach it. What matters is how fast you approach the first infinity (call it
infinity01) versus how fast you approach the second infinity (call it infinity02). If
you approach both at exactly the same speed, always the same distance from each, then
infinity01-infinity02=0. If you are always a little closer to infinity01, then
infinity01-infinity02 is a positive number. If you move toward infinity01 twice as
fast as how you approach infinity02, then infinity01-infinity02=infinity. The behavior
of limits is not quite the same as the behavior of numbers.
