Our science and morality is built upon one "fact": That experience matters, and that what you see is true. That simply isn't true, as we cannot prove anything based on experience: How do we know that invisible aliens aren't pushing all these objects to create the illusion of Gravity? We do not know. Even though the current physics may not be "true", it is plausible, or that we think it is true, or that it is subjectively true. There is nothing preventing someone with what we call schizophrenia to actually see objects "with mass" to float upwards without seemingly any force exerted on it. In fact, we cannot conclude that those ones with schizophrenia are seeing the real world as it is, and we just have the same symptom of schizophrenia. How do we determine normal vision and abnormal vision? By social categorization, or what we "think" is right versus what we think isn't. Even how we see the world cannot be proven to be true, let alone speculation based on it.
You cannot prove that the next time you push a shopping cart "forward" and nothing else, it won't push back at you and smash you to the walls. You cannot prove that the next time an apple grows ripe, it won't fall endlessly to the sky. Even though we tend to believe our experiences and more often times than not, you see the objects behave exactly like how the old people tell you through the physic textbook that they are going to behave, it is through YOUR vision. You can only prove that this time it worked, subjectively, but never that it WILL work next time, objectively.
Objective truth based on experience is equal to nonsense because objective experience is impossible and experience is not objective. Anything we consider true, based on experience, are, at most, subjective truths.
