Now we know that time and space are not the vessel for the universe but could not exist at all if there were no contents, namely, no Sun, Earth, and other celestial bodies. ~ Hendrik Lorentz
The idea of Nature having laws is inherent in science; especially physics, which more intently scrutinizes the nature of existence than other disciplines, which generally take materiality for granted (that is, assume naïve realism).
The essence of such laws is consistency. After all, a law is not a law if Nature violates it. In physics, this concept is embodied in symmetry: that physical laws are invariable.
In 1895 Dutch physicist Hendrik Lorentz derived the transformation equations which formed the basis of Einstein’s special relativity theory. Behind these equations, and special relativity, is the idea of an inertial reference frame, which is inviolable. That the laws of physics are the same for all observers is termed Lorentz symmetry.
Paradoxically, symmetry breaking is as important in physics as symmetry. To generate mass in subatomic particles, the Standard Model relies upon breaking electroweak symmetry.
