Not true. This assumes we Humans know everything there is about physics, and we don't.

I know this because...


a) We can't explain what nothing is. What is space? Hint: Nothing is probably something, we just don't know what that is.

b) We can't even unify quantum mechanics with general relativity. We have some really good theory, such as M-Theory, but nothing concrete and provable. Yes, even if the math for string theory works, we know no way to actually observe and test what a string is. #%&*$# that pesky planck length.

Hell, we're still arguing if particle physics is the way to go, and that we're not even sure of, because damnable models are still only models and we can make data look like almost whatever we want to fit into whatever we want. So what's to say we are experts in these laws? We're changing our outlook on things in science terms, all the time. (This is a snails pace, by the way, because that's how science works, but relative to time, pretty fast given how long agriculture has existed, and how exponential advances have become since the 20th century).
