We can trace our fundamental forces back to microseconds after the Big Bang. If we can trace them back this far, wouldn't the only way to change the fundamental laws of the universe be to recreate the conditions of the Big Bang? -Zach in Arkansas
What if gravity suddenly stopped working? Or what if e gradually came to equal mc3 rather than mc2? Could the fundamentals of physics really change? Or Is this just the stuff of science fiction?
The belief that some things are natural while others are unnatural is part of the common currency of human thought, but we rarely pause to consider exactly what it means to say that something is unnatural. It’s important to do so because this concept is politically very potent.
