Chickens and eggs might know how to read a flow
chart with just two boxes but more primitive creatures like
fundmental particles would probably opt for 5 or 10 fewer.
Especially if they have to follow it.

The absolute permittivity of the vacuum could be seen as negative
energy as it balances what we see as positive energy that
produced the motion to begin with. In fact the idea of negative
energy as applying to any force of deceleration may clarify many
situations although it is sometimes seen as inertia and being solely a
property of the event under acceleration etc which it is not.

So are you saying that the water pressure squeezes the
back half of a shark making it squirt forward.
The water pressure on the front half makes it squirt backward.

(don't answer yet)

That doesn't look like a good model for inertia because the forward
motion will increase the pressure on the front and squirt it backwards.

Let's try a space ship and two masses.
If the ship moves toward the forward mass,
the attraction will increase.

As the ship moves away from the rearward mass
the attraction holding it back would decrease.

That looks like it would accelerate. :-(
Let's grind the two masses up and scatter them across the
heavens... homogenously.

Now as the ship moves forward, it increases the
mass behind it, in the same proportion to the increase
of force dragging it forward.

Yep... that looks like inertia to me. But I am not
sure it says other than the total force of homogenous
background is completly nulled at the ship's barycenter
so it moves under the influence of the last imbalancing
force applied.. like a short motor firing.

If you grease a watermelon and tell two politicians there
is a campaign contribution inside you can probably get
a solution.
