Now, in my defense, I wasn’t lying per se; I was simplifying. That’s a perfectly acceptable and even advantageous thing to do in science. When you have some complex thing that you’re trying to understand or explain, it helps to make it as simple as possible so that the math and physics are easier to crack. It’s like assuming, at first, that Earth is a perfect sphere or that the sun contains all the mass in the solar system. Once you work out the basic equations that describe your simplified model, you can gradually add complexity back in—but in a way that makes the problem tractable.
