That means less than you think it does when the “laws of physics” keep changing as homo sapiens learns more about the outside world.
It is like a speed limit that starts at five miles an hour and over the centuries goes to the speed of light.
The concept of “speed limit” is amusing at that point.
The speed of light limit is not a law per se, and is actually based on other laws which have never changed since their discovery. In fact no actual laws of physics have changed since their discovery, but the discovery of new ones are always possible. Hence our understanding of physics may change, but not physics itself. No amount of “imagination” can make something go faster than light, for example, or back in time.
