Nope. When walking off the edge of a chair the only experience is the earth accelerating upwards.
There is no indication that anything is pushing you down.
This still is not a direct obsevation of the earth moving upward. It is an observation of the results of the earth moving upward, which also happens to be what the result of gravity would be as well.
First it's matter,
now it's energy,
sometimes gravity is a bend in the aether,
other times it's a Newtonian force,
and other times gravity is a sub-atomic puller particles,
seems that you guys haven't the faintest idea or piece of evidence for your "gravity".
At least we can see directly the cause for our gravity.
Here, you gave 2 examples of how gravity could work, and tried to make it look like there were more than that.
It was explained up thread that as far as gravity is concerned, matter and energy are interchangable. it's not sometimes one, sometimes the other, it's always both.
Newton, as far as I know, never described the mechanics that caused gravity, he only recognised it was there.
so you are left with gravity either being a bend in the aether caused by matter and energy, or sub atomic puller particles caused by matter and energy.
not as convoluted as you try to make it sound.
how many explainations are there for why the earth is accellerating upward at a constant rate?
