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?
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.
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?
Tha's not my model, it's Einstein's.
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?).
