It's a bit of a radical approach, perhaps, but what if gravity is the result of radiation pressure of ubiquitous weak photons that hold matter
together just as air pressure holds a ball of water together suspended in midair in an orbiting spacecraft? It means those photons are hitting every
particle of matter from all directions but are ever so slightly rarified in the directions over the horizon if you're standing on the surface of the
Earth but extremely rarified if near the event horizon of a black hole. The Earth is a weak shield against particles from directions over the horizon,
slightly upsetting the balance of radiation pressure from all directions, resulting in what we call 1-g gravity. But a black hole demonstrates just
how powerful that bombardment is by blocking a high percentage of it from one direction.
That's radically different from the way people normally think of gravity, but it also means that special relativity is a result of something like
wind resistance as you're trying to plow through that onslaught of almost infinitely weak but almost infinitely numerous photons.
If that's not how gravity works, then how do gravitons pass through the dense core of the Earth unabated and grab things and pull them back, not to
mention travel in the wrong direction from a black hole to reach out and grab things? If you say it's warped space, then what is space made of? If
nothing, there's nothing to warp but the one free proton per cubic centimeter verified by radioastromy to exist in space plus the molecular hydrogen
that goes undetected and the more rarified oxygen and other gases in space--so basically no Jello to warp.
And zero-point energy can be thought of as just a quirk of the theory of quantum mechanics, but inability to freeze helium and the Casimir force are
two indications that there is something there. But one more is the "mystery" of how electrons maintain orbit. Orbits decay, but electrons somehow
get a little boost from something that's right there for the taking. The tail of a comet is similar but can be explained mostly by its bucking the
solar wind, but even that shows that light pressure is real, not just something mentioned in the context of solar sails. Some experiments with SQUIDs
(superconducting quantum interference devices) also show that there is something there.
Einstein mentioned this but was pretty much ignored. it doesn't violate Special or General Relativity but shows a reason for them rather than just
models that only describe their consequences.
But it does leave open the possibility that UFOs can do exactly what the late astronaut Deke Slayton, former USAF Chief Public Relations Officer
Colonel William T. Coleman, and many other pilots, police officers, Skyhook balloon trackers (once together with an astronomer) and others have said
they clearly witnessed.
And astronomers like to say that the galaxies beyond the Hubble horizon are moving away from us faster than the speed of light, although the existence
of molecular hydrogen in space would seem a better explanation to me. It was shown to exist and written up in Nature
in the late '90s but
somehow remains pretty much ignored.
