Hi Crusty,
No, my Friend, Genesis is not science. But, IT IS the history of science. You see, my Friend, when "In the beginning God created the heavens and the earth" (Genesis 1:1) -- part of that Creation was all the sciences, and all the laws governing those sciences.
In Genesis God does not try to explain the sciences. He just tells us the history of them coming into being.
Keep in mind that when science discovers something new -- it may be new to them -- but God always knew about it. After all, He created it.
God bless, have a wonderful, blessed day,
Bill
