This is basic, *basic* science. This isn't advanced physics. This isn't even freshman college physics. This is grade school stuff! If you want to debate intelligently on scientific issues it really helps to understand some basic science, such as the electromagnetic spectrum. I don't expect you to turn around and drop everything and believe the earth is 4 and a half billion years old. However, with some basic understanding of science will come the realization that the earth cannot be merely 10,000 years old.
Facts are immutable!
