Modern Materialistic Physics has spent so long bolstering and propping up the "gravity comes from mass" theory for a VERY, VERY long time.
They started with Newton. And, remarkably, very soon after, an insane, very rich person decided to do an experiment that measured the gravitational pull per mass. And this, sorta worked for explaining our solar system and things falling on earth.
But not really. There were discrepancies all over. Notably the orbit of Mercury.
So, Einstein stole some ideas and came up with the Theory of Relativity which mostly explained things. It was better at predicting the orbit of Mercury. And it was really complicated so only really high IQ people could even ponder it.
But then, we found it didn't work for the galaxy. There wasn't enough mass to keep it from flying apart. (even with an unseen, unknowable, unprovable black hole at the center) So, they invented "dark matter" (you need to say this in a hushed whisper/spooky voice). Matter, which had to be there to balance the equations, but you couldn't see it.
All of this effort to bolster and prop up something that is completely wrong.
So, what happens when it is shown to be completely wrong, by the advent of flying cars?
Out comes, to the public, the floating platform.
Already, your average guy in his garage is making things that float in the air. They call them "lifters". They are a capacitor, charged to very high voltage, and they lose weight.
They just sorta float in the sky, like a brick doesn't.
The next step will be when they start to work out that a high voltage isn't all, but a frequency induced on it can alter and enhance the lift.
And then, the floating platform comes out.
It will probably will be used as a forklift type device at first.
But, not for long. Guys do all kinds of things with forklifts, pallet trucks,…
The flying car
So, we got these floating platforms. Not much longer after that, we will see flying cars. (or maybe Back to the Future hover boards if they can make them small enough)
These things will be everywhere. It will be undeniable.
The govern-cement already has "contractors" working on floating platforms, but those can be denied. We don't see them, therefore they don't exist, and physics doesn't have to rewrite the text books.
So, what happens when we have flying cars, and they are not "anti-gravity". They work on electrical principals, and it affects weight, not mass. Everyone will see it, and those in the ivory tower will not be able to wave it away as just someone's fevered delusions.
There has already been so much evidence that physics should have put the idea, of gravity as a result of mass, to bed. But no, they ivory tower priests have done everything to avoid reality.
So, these platforms are coming, and they will have to rewrite the physics books.
What is gravity?
We don't know. We have some good ideas, but they require changing so much of our understanding of physics, the shape of the world, and everything. Sooooo, we are left with incrementally changing things as we learn new things from exploring our world through a new paradigm.
Gravity appears to be an aether phenomena. Similar to magnets. Aether, where the electricity flows (it isn't inside the wires) and light propagates.
A better explanation of how magnets work is that space in between them is collapsing, or being sucked in. (Modern materialistic physics believes that "unicorn particles" shoot out from one magnet, and then impact the other magnet, causing it to come closer. We have seen as many of these particles as we have seen unicorns)
Flemings Right Hand Rule (image from wikipedia)
So, we have the right hand rule in physics. Electric flow, magnetism, force. So, if you have electricity flow in this direction, and magnetic flux in that direction, you have a force in the perpendicular direction.
The earth has a magnetic field. It also has an electric field (we can measure different voltages at different heights above the ground) And so, we would have a force, pushing us toward the ground.
The electric universe model explains a lot more about how the solar system holds itself together. Aether theories make a lot more sense, and are far more easy to understand than Einstein's stolen Theory of Relativity.
We don't have all the answers. We don't have pat responses to all the questions young minds would ask. But, these areas will be explored when it is right in our face.
And the "Modern Materialistic Physics" Book will be thrown in the dust bin.
