Haha, interesting! Who says anyone set them? If you believe in parallel universes, some theories state that there exists a parallel universe exists for every other possibility that could have occured – this might mean there are parallel universes where say, the speed of light is 100 mph (I can’t picture that one!), or where gravity is a repulsive force.
Or maybe God…if he exists!

I’ve always thought the word “laws” was a bit dodgy, to be honest. The ‘laws’ that we talk about aren’t really ‘laws’. Often they turn out not even to be all that accurate (like Newton’s laws of gravity…)
I can’t say who “set” nature up the way it is, perhaps that’s the job for philosophy not physics. But it is our job as scientists to find out how it works. Then we can have theories, models and “laws” and use our understanding to make the world a better place.

Deep! Mother Nature? God? Actually physics can also explain a lot of the laws of nature 😀

Good point – I like the idea that there are many universe out there in a multiverse and that the laws of nature are different in each one. There is a great book called Just Six Numbers which explains how all the laws of physics are determined by just six constants and that only those need to be explained to explain the laws as they are.

When you drive 50mph on 30mph road if police sees you are done because you have broken the law. The laws are set because to live in a paceful environment which are made by the governament. BUT the laws of the universe seems to be set by some sort of external govarnament and that is God, inorder to live in a peaceful universe, don’t you think?
