    He said as an example against gravity being non-absolute was an example of imagining a universe with floating islands. But that isn’t a universe without gravity, that universe has gravity holding together the rocks of the, mountain and the planet above it. Sure gravity works differently than expected, but that is the theory of gravity, not the existence of it.

    A universe with no gravity is one in which all matter just flies away from all other matter endlessly. No stars, no planets, no chemical reactions. And such a universe cannot exist with life in it, so you cannot logically imagine a universe with us in it that has no gravity. Thus we can know gravity does exist. It’s the how gravity works that is up for debate in question, but it does absolutely exist.

    You’re too stupid to talk to it seems, because no where does he say gravity itself does not absolutely exist, but says that our ideas of how gravity exists could be wrong.

      He then goes on to show that even the most basic sensory statements, e.g. “There is an apple in front of me” are subject to the hypothetical fallibility of the senses. He reiterates that any synthetic proposition, even the most basic observation supported by mountains of evidence, is still impossible to assert with 100% certainty. Evidence for the existence of gravity is still within the purview of synthetic propositions, and therefore falsifiable in base principle.

      I abandoned physics (I know more about our understanding of gravity than you do) in a professional capacity in favor of mathematics (I know more about absolute certainty than you do). That is the only actual realm of absolute certainty (and that is only because it is a collection of definitions, not a synthesis of observations). You do not understand basic logic. You use certainty carelessly, which is horrific mental hygiene for a scientist. You conflate science with the political bureaucracy which surrounds it.

      Hop over to IHPST and tell them your perspectives. I’m done, maybe they can undo the damage.

        the hypothetical fallibility of the senses

        Which is just bullshit philosophical crap. In order to even have senses there must be gravity in the universe, so once again it is impossible to logically imagine a universe without gravity.

        And as I have said before science is just a way to understand our perceived reality. If all our senses are flawed it does not matter because that is how we collectively perceive the universe, and that is what science is trying to explain.

        I abandoned physics (I know more about our understanding of gravity than you do)

        I took undergrad physics too, so doubt. And you’re still a lair, because you would have brought up your physics background way earlier in the conversation if it was at all real.

          As I said, mixologist in a lab coat.

          QM? Relativity? Doubt

          you would have brought up your physics background way earlier in the conversation if it was at all real.

          Why? Personal credentials are not evidence. Plus, as repeatedly demonstrated, you would’ve called me a liar anyway.

          I’m done with your rot-addled, pseudo a-priori nonsense.

            Tell me how a universe without gravity could exist with us in it then. Because that’s the bar set for whether something can be claimed as fact.

            QM? Relativity?

            Yep, covered both.

            Why?

            Because prior knowledge is relevant to any discussion. And I didn’t call you a liar until you lied about doing a double blind astrology report. I said you fell for the Barnum effect before that, which you have yet to acknowledge.

            Why skirt that issue? Why refuse to engage with the possibility you fell for the Barnum effect?

            I’m done

            Oh please be true. Because you’ve said that half a dozen times now, and I’ve made it quite clear I would be happy for that to be the case.

                Look in a mirror. You refuse to answer simple questions that are entirely relevant to the conversation, and are completely unyielding to alternate points of view.

                And I type this from my lab waiting for a biosensor to baseline so I can do real scientific experiments today.

                    More science than you’ve done in your life.

                    I thought you were done with me, or are you finally going to answer some questions? Cause I did ask you how you imagine a universe without gravity, but us in it could logically exist.
