Daddy: Any body with only two standing points will fall because of the gravity.
Kiddy: How the bikers can run?
A gallup made recently shows that a third of the french citizens (even almost educated) still believe that the sun runs around the earth.
IMHO the gravity don't exist: it's just an human way to explain an observed phenomenon.
Take a small ball in your fingers: the ball is linked physically to our world and is expanding with us.
Open your fingers: the ball recovers it's freedom, remaining at the same place of the outer space, finally reaching the floor...
Why? Because our world is in expansion with an increasing speed (wich doubles every second).
During the time the ball was free we have been increased and all parts around us (the reason why we cannot detect this expansion).
The ball was not falling, the floor reached it. This is the big difference wih the common explanation.
Nevertheless the laws of the physics (in particular the rule x=1/2gt^^2) are still valid.
The last question: how to prove this? Easy: the mass of the ball should be reduced, measure it.
The problem: The measurement meters have been expanded meanwhile.

We need sometime to reverse our way to observe the phenomenons.
I cannot imagine why nobody though on this before, including myself? It is so simple!...
