Avocado, not Gravity

If one peels an avocado, sometimes some will be left on the seed. This
will slide around the seed, but will adhere to the seed. Aha!

Maybe there is no gravity. There are shells of space around the sun,
eacn corresponding to an avocado seed, and the planets move around these
sheels, but cannot slip off. If a comet seems to be attracted by the sun's
gravity, it is just temporaily adhering to the shell, which slows it down
for a while, and bends it - all without any force of gravity. So gravity is
not necessarily curved space.

Space is then full of matter, and possibly there are shells of different
densities.

Of course, if the sun and stars actually revolve in shells around the
Earth, this is a little harder to picture, I guess.

On the other hand, space may be an illusion. It may be just a sort of
fill-in-the-blank hallucination. Thus, if a quantum event can go from here
to there without crossing the intervening space, this may be because there
is no intervening space - how does one picture space?

In some higher dimensional geometries, there is more space on the inside
than on the outside, like Dr. Who's phone box. But if there is no space,
then inside and outside may be some kind of cognitive hallucination.

If there is no space, how can gravity be curved space? But I can picture
an Avocado.
