I think a lot of people are missing the point of my question here. I believe it's you who are missing the point. Acceleration is irrelevant, it's how it's transmitted that matters. You feel gravity because the ground prevents you from falling exerting an opposite force, that is transmitted mechanically along your body. There is no difference between free falling and no gravity except in monster gravitational fields like the one close to an event horizon where differential gravity (tide) could torn you apart. In any other situation you can safely assume that all the points in an object are pulled uniformly.

Direction is a fundamental aspect of acceleration, no? I'm also not asking about what our brains are conditioned to feel. I am simply asking - is the constant acceleration of orbit fundamentally different than no acceleration, even if both would feel the same? No-one has answered that in a compelling way. Because to be clear - in one, no forces are being applied and in another, there are forces being applied (how else would you change directions?).

  I'm also not asking about what our brains are conditioned to feel. Brain can't feel without senses input. is the constant acceleration of orbit fundamentally different than no acceleration...? No. how else would you change directions? You don't. You keep going straight, space is deformed by gravity. But even if you look at it like in classical mechanics, the effect is applied uniformly to every particle of your body, so it makes no difference. Ask yourself this: how do you feel gravity right now?

    >No. Ok but why? >You don't. You keep going straight, space is deformed by gravity. Yeah, and if gravity weren't deforming the space, objects otherwise in orbit would move differently. That's just changing the mechanics (presumably in an attempt to appear more knowledgeable?) to avoid the question of why two wildly different scenarios (no forces vs. offsetting forces) are the exact same. >But even if you look at it like in classical mechanics, the effect is applied uniformly to every particle of your body, so it makes no difference. Again, my question is why in your model is the uniform application of a force the same as no application of a force? >Ask yourself this: how do you feel gravity right now? You don't have a sense for your own weight? I do and I don't know how to describe that feeling beyond that. If I were in a true extremely low gravity situation (like deep space) I would feel differently.

      presumably in an attempt to appear more knowledgeable? O_o Again, my question is why in your model is the uniform application of a force the same as no application of a force? That's not my model, it's Einstein's.
