I really was fascinated with the gravity pic of Earth. Now that science has been drug kicking and screaming to the altar of an extinction event of 12,900 years ago, we can go forward with how advanced, how wide-spread, etc.
Let's suppose that we were more advanced than now but that fewer of us enjoyed the benefits. Let's further say that our gravity was such that there were pockets of anti gravity ala Pandora's floating mountains. So far this does not wander too far from myth. Let's assume that the elite few were able to enjoy the benefits of anti-gravity primarily at the Equator somewhere like the Cayman Trench which could have been land from the Yucatan to Cuba. Let's stop there.
Science done by Miles Mathis says that energy (photons) enter the Milky Way along the axis and are spun up to matter. I say it is then deposited into the mass of the equatorial rim of the Milky Way in a non-locality event as the galactic capacitor overloads.
As for the 12,900 year old extinction event, I propose that our heliosphere has been the subject of compression since the creation of Fluff, our local gas cloud, NASA says is 10 million years old. We are about 5. Since that time our heliosphere has been compressed and there have been various and sundry theories to explain our unexplainable history. I suggest the compression of Earth is due to the incursion of a small bit of the densest matter possible (George Gammow). I suggest that this bit of dense anti matter was caught between the matter of Sol and the matter of Centauri and has been repelled back and forth. I suggest that only briefly does this anti matter enter through the ORT shell and force the heliosphere of Sol down to Mercury, exposing all the other orbiting bodies to cosmic rays, heating, and expansion.
I further suggest that prior to the extinction event of 12,900 the elite of Earth were aware of and anticipated this antimatter's arrival. We call it G1.9 today. I suggest the time frame of its effect on E lessened each appearance and the elite manipulated the anti matter of E to last from appearance to appearance. This changed to lessening the heating effects due to core heating when the sky rivers supported by anti matter collapsed 12,900 years ago. G1.9's appearance now suggests that it has burped the quantum gas that allowed it to be an LT (light terminus) starbit and became a neutron shedding neutrinos heavily. It is now inside the ORT but will depart at the end of 2012 and the heliosphere will rebound to what we think of as normal with extremely heated gas planets now included. Hence the heat problem.
I further suggest the Second Law of Thermodynamics rules and our home Earth has lost anti matter and become heavily matter, a gravity well.
Velikovsky was correct in many things, Venus was nearly all molten 600,000 y ago. Miles Mathis has much info to share on current physics updates.
