Infinity

So I was looking at some pictures shot from the Hubble telescope and it got me thinking about infinity and what it really is. I have come to the conclusion that mankind cannot really comprehend what infinity is. My brain started hurting the more I thought about it. I look at these pictures and wonder is there an end? There can never be an end, because what is an end, a wall? If there is a wall, then there is something on the other side. If it is a solid object, how thick…infinitely thick. And on the other side of this object…more, infinitely more. See, your brain is hurting now too. Think of walking in a circle. You can never reach an end. You can walk in this circle for an infinite length of time and never get to the end. Looking the other way, small. How small is small? Guess what, infinitely small. The scientific community uses their resources to find ever smaller particles. But beyond these are even smaller particles, infinitely small. So here we are; a speck in an infinite space and time. In other words we are infinitely insignificant!!!! Now my brain really hurts!!
