Default The mystery of gravity

The great physicist Isaac Newton created a mathematical model of gravity,
and it is still in use. The basic idea is that masses attract each other,
and there must be a force between them.

What kind of a mechanism is needed to make that possible? We need
between all the atoms in the universe, each atom being in connection with
all the other atoms, all the time and immediately, at the speed of a

If we understand this we know that the model cannot have anything to do with
reality. So, a better explanation is needed.

Curvature of space was a brilliant idea. Gravity is not an attraction
between masses. Objects in space are in free-fall, and there is no force
acting on them. Falling in gravity field is relative acceleration, not real.
Objects are moving straight ahead with constant speeds. It is space, that is
not "straight".

But there are problems, too. When we drop a coin, is it falling because time
passes differently on it's upper and bottom sides? We ought to believe this
if we believe Einstein's explanation for curvature of space. And the biggest
question is the reason for curvature. Einsteinian gravity needs an
interaction mechanism between gravitational mass and space around it. We
still need something that can have an influence at the speed of a thought.

Einsteinian gravity is a part of modern physics, but something important
seems to be missing. It cannot describe the reality.

There is a possible explanation for gravity, but it is the only one:
