I am absolutely sure that we have NOT learned everything there is to know in this world. I am equally sure, however, that there are some things we HAVE learned. There are some things we DO know. There are some things that have been exhaustively researched, thoroughly tested, and are now clearly and completely understood. Conservation of energy is one of those things.
