Science does not have a limit neither does our understanding and knowledge. It is always expanding, fluid and moving. Science along with our knowledge is like water. It carves new paths, etches new landscapes and sometimes tears down everything we know. Sometimes there is a drought and our knowledge is barren but then, suddenly, there is a downpour and the water fills the land. I believe we are living in another age of downpour. Science as well as, our knowledge of nature, mathmatics, the universe and our bodies is at an all time high. People are embracing science as they did during the renaissance.
Theology is like a huge, giant boulder. Stagnant. Static. The effort it takes to move it is overwhelming. Once it reaches it's size thats it. It can only get smaller, broken into smaller pieces.
