    Also, quantum mechanics is not math that feels right. It is literally the best most experimentally validated theory we have to describe the universe at this time.

    Maybe some day we can do better. But it certainly isn’t based on a feeling.

      Quantum mechanics proves that quantum mechanics is valid.

      It is the mostly widely accepted interpretation but it is not the only one.

      We’ve been confident before and spent centuries chasing literal ether.

      The Copenhagen interpretation is just that, an interpretation.

      We’ve chased it for decades and are no closer to resolving it with classical mechanics.

      I’m sure future scientists to scoff our demand that there be an “observer”

      It still cannot account for gravity.

      The formulas pretend it doesn’t exist. It reminds me of a physicals 101 class pretending friction doesn’t exist.

      Friction exists and so does gravity, therefore they are both pretend.

        Thats not even true, we’ve been trying to come up with a unifying theory that encompasses quantum gravity for a while. This stuff is hard dude. And you don’t know what you’re talking about at all.

          Trying and failing.

          Is it not possible that it’s “hard” because we’re chasing the wrong path.

          This isn’t something I alone think. You seem to be under the impression I have a less than Wikipedia level understanding of this. I do not.

            This reminds me of how someone illustrated the machine learning problem of what I want to say is called “gradient descent”. This was way back in the 2000s before all the more recent AI stuff.

            Basically the problem as I remember it being described in a Tedtalk was if you think of a problem like a sphere with a surface and a bunch of tunnels at the surface, where only one leads to the core (answer) of the sphere. Some tunnels might get really close to the core, but only one leads into the core. The AI would get stuck diving down these holes using insane amount of computational power trying to dig for the answer, not realizing that if it backed up a bit and went down the hole next to them they could reach the core (answer).

            One way to help this problem was developing the game “Foldit” which allowed regular old users to manipulate the proteins themselves. When people had foldit at home running they would notice that the Screensaver displaying the folding would skip over what seemed to be the right shape and would get frustrated that they couldn’t help guide it.

            This might be a different Ted Talk, but it is about the same subject.

            No, it’s hard because the energy levels that we have to have to test things at the plank scale are much higher than anything we can achieve right now with our current level of technology. Plenty of theories make predictions about quantum gravity, string theory, M theory, lopp quantum gravity. There’s even a few out there theories that just try to modify newtonian gravity.

              It’s “hard” because we didn’t find what we expected at the energy levels we targeted.

              There is too much funding behind it now. No one can question the status quo and maintain funding.

                As I said, you don’t know what you’re talking about. That’s all there is to this conversation.

                  You are confused.

                  You don’t know what I’m talking about.

                  That doesn’t mean I don’t know what I am talking about.

                    Dude, I have an aerospace engineering degree. May not be in physics. But I know enough about it to call put bullshit when I see it.
