Essay Abstract
Physical laws are regarded as fundamental because they are valid everywhere and always, without exceptions. The type of physical laws is to a great extent determined by the properties of time and space. If these properties change, the type of physical laws will change. But the properties of time and space might not be invariable and most probably depend on the initial conditions of the creation of the Universe (the Big Bang). Under different initial conditions the properties of time and space may be different. The essay presented discusses the issue of the properties of time - how fundamental they are and how a change in them would affect the physical laws known to us. The connection between the one-way direction of time and the physical laws is examined as well as the dependencies between the thermodynamic and the information arrows of time. The essay also discusses how a change in the number of time dimensions would affect the known physical principles: the causal structure of a space-time, the Lorentz covariance, the principle of invariance of the speed of light, the CPT-symmetry, the existence of antiparticles, etc. The conclusion reached is that the fundamentality of the laws was largely determined by the initial conditions of the Big Bang.
