Everyone knows that gravity is what holds us down to the ground. Well, that is what everyone is taught. There are many other explanations, but we aren't taught about them, we are only told of one, and are made to believe it is correct, and that there is no reason to look elsewhere.
The Cavendish Experiment
The entire gravitational constant that science assumes, is the work of one crazed "scientist" (Henry Cavendish) who did some experiments in an old barn with supposedly some large metal balls. There are even rumors that he had large balls of gold.
The experiment is quite simple to describe and almost impossible to do. You hang a bar with weights on each side from a metal rod. That metal rod has a torsion strength that would resist turning. You bring a large mass near the suspended weights and measure the movement of the weights. Gravity should cause the weights to move towards the mass. You measure the movement, you calculate the torsion resistance to that movement, and you come up with the gravitational constant.
The problem is gravity is such a small force that the movement would be almost impossible to measure. And if you could measure a force between two objects that could be suspended in a building, then things like paper should stick to the wall. And a mountain climber should stick to the face of a rock cliff. But these things don't happen. The paper doesn't even sorta stick to the wall while sliding down the wall towards the earth (bigger, more gravity).
Gravity explains the motion of the planets... sorta
Gravity sorta explained the movements of the planets... but not quite. And Mercury's movements really defied the law of gravity. And so, the theory of relativity got thunk, and it explained the motion of Mercury better. (Ah yes, space is curved... by mass, which causes gravity.) However, there is a lady who has explained the motion of Mercury even better by applying the law of equal area in equal time. Accurately describing the motion of Mercury to the best our instruments can measure.
Big G, the gravitational constant.

Is supposed to be a constant... but its not. When measure all over the world, it varies by place and by time. There are even some places where it varries hugely. The science community has gotten together and set G... because, its supposed to be a constant, so all of these variations must be due to errors in measurement. And thus, anyone looking into why G varies from place to place is shunned and silenced.
Defying gravity
And then there is several effects that just defy gravity. Literally.
There was a scientist who wanted to know what would happen when two metal plates where charged to very high voltages, but weren't allowed to discharge to eachother. (a capacitor, or in the words of Tesla, a condenser). So this scientist created two metal discs, and carefully encased them in plastic resin. Making sure that there were no air pockets; making sure the dialectric was as perfect as possible. Then he charged the plates to millions of volts. And the thing floated. This is known as the Biefield-Brown effect. (were you taught this facinating piece of science in school?)
Then there was a couple of scientists in Japan who were working with gyroscopes. They noticed when you spin a gyroscope clockwise at very high RPMs it loses weight. They did all kinds of experiments to make sure it wasn't air, or other objects, or temperature or anything else they could think of.
Given these few examples, we can easily stick a fork in the "theory of gravity". It is obviously not directly tied to mass as we are taught in the text books. But what is it?
So what is gravity?
Some other theories are that we are held to the ground by the pressure of ether flowing inward to the earth. There is all kinds of fasinating stuff in ether theories.
Another is that we live on a flat, immobile earth.
Still another is the electric universe models. Where electrical forces are what holds things together.
Or it could be that love holds us together. Gaia's love for us draws us closer to her.
