Lawrence Krauss -- Are the Laws of Nature Always Constant?
August 5th, 2023 at 6:16AMNature is constant. The laws describing how nature works can be right or wrong. They can be changed to better fit whatever part of nature their describing. If nature wasn't constant, if it changes even once, the concepts "law" and "nature" and "constant" would have no meaning. For instance, if it's a law that an object in motion stays in motion, then we observe an object in motion that does not stay in motion, it's not the nature of the object or how it acts that is wrong. It's the law describing objects and the way they act which needs to be updated or outdated. Our understanding of nature has changed. Nature itself has not. If the nature of anything could change, there would be no laws of nature. Nothing would be explicable.
Think of the Schrödinger's Cat metaphor. You stick a live cat in a box and because you can no longer see it you don't know for certain if it's alive or dead, but you know it's still in the box. That's nature. A cat can be alive or dead, but whether you're watching it like a hawk or not, it can't just fucking disappear.
