"The difference between genius and stupidity is that genius has its limits." -- Albert Einstein.
The attempt of science is to understand the world around us and to explain it in a set of logical theories. The more we learn the more we realize we did not understand the universe at all. The more we learn the more our theories change.
If you want truth see philosophers and theologians. In science we teach the best guess theory at this moment in time. However the bowling ball that falls on your foot still hurts no matter what theory underlies the science. *)
