Newton and Einstein are full of shit.
Objects fall not according to a pull toward other objects but because of a surface tension matrix known as the force of buoyancy.
This is why attempts to construct the universe through this system always run into unresolvable problems that are rule-patched by creating more complications.
If you want to imagine buoyancy, think of a tiger pit, where the ground is bamboo spikes below, and a layer of soil and leaves above. A rat can cross the trap without incident, but a tiger putting all fours on the trap breaks the surface. Einstein theorized that if a man wiping windows fell from a patent office, in terms of his hat, wiper, and himself, all would appear to hang together in midair. He was right, but not because of gravity or relativity. Back to the rat and the tiger. If the rat is nearby the pit when it breaks, it now also falls. In the same way, a feather tends to fall at the same rate as a nearby falling anvil. The anvil displaces the air around it, and air rushes in to fill the gap, catching the feather in thin air suction. This is called wake, it's essentially an object creating a "splash" in the air.
We can prove gravity is false by observing that water in the same elevation (say, a fish tank) always moves from more dense to less dense. Just as a more dense rock falls through the less dense air, bouncing or rolling as it hits solid ground, in our fish tank model, if I construct a removable glass separator and fill one side with water, then I lift the separator, the water rushes toward the other side until it levels. At no observable point is there a force that draws objects to objects of more mass. Rather the bird that stops flapping its wings falls through air of less mass than itself.
Now, some of Einstein's or Newton's ideas have some merit, or half-truths. But some are real lies.
Also, if gravity isn't a force, then why did Einstein use gravitational constant "G" (Unit of force "N" can be seen in the unit of "G") in his equations?
Because stooges tend to agree with one another. What, you think two people agreeing is proof?
