I claim to understand it well, but that doesn't mean
I have or need to explain it.

The phrase above is valid with an exception, external
forces can cause objects to depart from straight line motion.

But there are other things besides external forces
that can cause a departure from inertial motion and follow
a curved path.
One of those things is gravity, which is not an
external force.
Another of those things is unequal pressure inside
a container. And maybe rockets could be considered
another.

Participants in a discussion should be able to add
to a discussion.
In General Relativity, either time or space, or both
can be curved, substitute "spacetime" at will.
In the Divergent Matter model, the expansion is
not linear, units of both dimensions lengthen, the second
constantly lengthens.
This leads to an experience by animals that seems
as if dimensions stay the same, and that time is linear.
But in orbital motion, assuming a circular orbit of
a small object around a large planet, the only thing
that brings the two closer together is the expansion.
And the only thing that keeps them apart is the
tangential vector.

But in an elliptical orbit, the tangential vector
and the velocities change, the observed velocity
is altered by the lengthening second, giving the
same illusion as an external force acting.

This may appear to be more complicated than
Newtonian concepts, but nature may consider it to
be less complicated, because with external forces,
the source of gravity would need to have almost
infinite power, not be shielded by any material or
means, and be undetectable by any means.

That is what I call complicated, and it is
impossible. Changes in size may be hard to
accept, but other things are relative without
any problem.
