    I know of course but for the people in the cheap seats… What are the first four?

      “All of the forces we experience every day can be reduced to just four categories: gravity, electromagnetism, the strong force and the weak force. These four fundamental forces govern how all the objects and particles in the Universe interact with each other.”

        I thought gravity had been reclassified as “not a force” since it doesn’t have a carrier particle and is a fundamental property of spacetime interacting with mass?

          Just quoting the article, but Dr. Wikipedia also lists them as part of the four “fundamental interactions”.

          Not an expert in any way, but there’s this short article that seems to go into that some, that it’s more an “emergent force”, but then he goes on to say that if we’re not defining gravity as a “real force”, then we can’t define the other forces as “real” either. It just seems like a bunch of disagreement over terminology that I’m not nearly educated enough to care about the distinctions being made.

        But electromagnetism and weak force has already been understood as a single force, electro weak. So they are not fundamental
