I think it is safe to say that neither of them are completely correct.
What needs to be re-considered when talking gravity, and taking into account, are theese things:
- rotation of earth around its own axis
- rotation of earth around the sun
- rotation of our galaxy
- in other words, centripedal and centrifugal spiral motions and their effects
- double functions, that both pushes and pulls
- relations and interaction between positiv and negative charge and forces
- the socalled "frame dragging" effect
- and possibly alot of other things
sometimes we need to turn things around...
In the search of trying to understand what holds things together, we seem to have forgetten to try and understand what keeps things apart.
There is indeed a double effect existing, of both push and pull, not just pull...
Gravity is depending on both the forces around and within...
- Why does a blown soapboble always become round in shape?
- why are all the planets round in shape?
- how come the dinosaurs didn't collaps under their own wiegth?
Gravity could indeed have been a variable that have changes over time.
We most remember that our lifetime on this earth is but a drop in the ocean of time.
And maybe the gravity of earth was not so strong in the old days, allowing things to grow into huge proportions, and over time changed, to reach a
state of equilibrium with the surroundings?
We must always remember that we are in constant movement within a system in motion.
All science communities are still trying to get a grasp of gravity, and the issue is still open for debate.
