### Why acceleration requires collisions

PSI Blog 20180711 Why acceleration requires collisions

“In your newly released article ’The Physical Cause of Gravitation',[1] you wrote that the unseen particles involved in these collisions provide the acceleration that drives gravitation. But if those particles stop existing, will gravitation also stop occurring?”

[GB: Per Newton's Second Law of Motion, all causes (i.e., events, changes, etc.) involve collisions resulting in the acceleration of the collidee and deceleration of the collider. This is the guts of the philosophy of mechanism and its proposition that the universe consists of matter in motion. Indeterminists, especially regressive physicists and religious folks, do not necessarily believe this. That is why some especially naïve people still believe in ESP (Extra Sensory Perception). It is why many of today’s physicists say that Einstein’s relativity overthrew classical mechanics. It is why I say they are regressive. It is why my gravitation paper was just rejected outright by the editor of Physical Review Letters (returned in 24.46 hr without review). It does not take much training in regressive physics to reject the first sentence in that paper:

The physical cause of gravitation is simple: the collision of one thing with another.

As I pointed out in that paper, gravitation is acceleration. Every acceleration results in a deceleration—simple. The fact that the particles doing the accelerating are unseen is no big deal. Air particles cannot be seen either, but they do plenty of accelerating. Abhi, you are right that if aether particles stopped existing, there would be no more gravitation. Similarly, if air particles stopped existing, there would be no more breathing or hearing.

You also ask: “Besides, why do you assume they are “aether” particles when we do not know exactly what these particles are?” There is a lengthy history in which aether has commonly played a part.[2] Reread my paper to review Newton’s effort at hypothesizing a medium accounting for gravitation. Aether is theoretically necessary because, according to Newton’s three laws, there are no true pulls in nature. The recent LIGO experiments show that light and galactic shock waves (regressives call them gravitational waves) both travel within the aether medium at the same velocity—the speed of light. All waves require a medium. That is what Sagnac found in 1913, correctly calling it “aether.”[3]

The Michelson-Morley experiment[4] was searching for a medium in which their hypothetical particles were not assumed to collide with matter. I now use the “ether” spelling for that kind of particle, which we now know does not exist—all things are in motion, capable of colliding with other things. Aether, on the other hand, does exist, comprising the “dark matter” entrained around all matter. It is entrained because it becomes decelerated upon colliding with other matter as explained in my paper.]
