Well that's a different issue altogether, I largely agree but not 100%.If I see something happen I don't need to "believe" it. I WITNESSED it. Thus my question for understanding is rooted in the material world.
There, right there is an assumption!! plenty of theoreticians question that assumption too, whether nature is causal, deterministic is an open question.Cause and effect rule the day.
Newton's theory assumes time is universal, the same everywhere at all times, it assumes that.Physical Laws are not assumptions.
Newton's theory assumes a universal reference frame against which all observations are relative to, it assumes that.
Newton's theory predicts the luminiferous aether, it pops right out of the theory - these kinds of things were regarded as laws, true, absolutely true.
Right, so tell me how something you claim to KNOW is true can at the same time be untrue?But, as a scientist I understand that if improved instruments come along, that allow us to understand a physical law at an even deeper level, then those laws can change, if however slightly.
General relativity is NOT an improvement of Newton's theory, it is a replacement, it abandons universal time, it abandons a universal reference frame and so on. Einstein did not take Newton's theory and refine it, expand upon it, he completely abandoned the guts of the theory, the "laws" it was based on.Newtonian physics is still able to describe 98% of the physical world. For the remaining 1.5% we have Einsteinian physics, and an improvement on that is the Feynman Constant, and most certainly there will be some new genius come along who will open a new door to something even greater.
Einstein believed that the laws of nature are the same for all observers, their mathematical form was identical no matter where the observer is or how the observer might be moving, Newton most certainly did not assume that.
Give me an example please of a law of physics that you KNOW is true.All grounded in the material world.
No belief system needed. Just hard work.
