3rd statement nulls the idea of UA.
How can ua apply to us and stars and sun if when i jump, i separate myself from the earth, the thing that is pushing me forward?
How does a sun get pushed upwards?
Jane went into a mindboggle of a math loop trying to show relativity to ignore the speed of light "problem".
But how can a floating object be affected by ua while a grounded object cant?
Why do grounded units rely on the earth accelling up to push them along?
If ua accells everything then grounded items should also be affected.
If im accelling up because of ua pushing on me (ignoring the earth) then i should be able to jump and stay at that height.
Analogy - in a shopping cart on a high hill.
Rolling down the hill at a constant accel.
Throw a ball from within the cart forawrd, down the hill.
Ignoring windresistance and friction -
The cart will never catch up to the ball.
The gap between ball and cart is what would exist if i jump.
