Natural Mechanics
In the Universe prior to carbon based life...natural things were occurring and going on without the name, or concept work, without any measurements being acquired, and without any predisposed intentions. There was Matter, there was Light, there was Space, there was Pressure, there was Motion, Electricity and Magnetism. When matter interacted with other matter there was pressure brought to bear, and things happened as natural physical phenomena. There was Lightening, there was static electricity. And there was probably magnetic lodestones and polar magnetic locations. I admit this is fantasy... since no-one was there to confirm it as reality. However for my purposes I am calling it reality based on pretty good evidence that it had a high probability of being that way. There had to be atoms and sub atomic particles... but if I were there just observing, feeling, tasting, listening, and smelling__ things like atoms would not be very obvious.
The work being done in this era was: rock pushing rock. Fluids pushing earth. Particle radiation set in motion by pressure. Chemical reactions causing heat, causing pressure. Wind blowing dust impacting rock and matter causing erosion...
No-one measured the work being done throughout the Universe then; so there was no mention of the ability or capacity to do work... called energy... Mass was not a concept. Gravitation was probably real phenomena, but we still don't know how it works... so it would need more thought, along with any observations, to make it obvious.
I am using three billion years ago on Earth as a basic natural platform to work from. As the progression of history went along and new things cooled, solidified, changed; and new things came into being__ with our present knowledge base, and hopefully scientific logical productive thinking__ what would we keep, what would we modify, and what would we toss...?
I take this tact to maybe sidestep personal pride, prejudice, and habitual assumptions. I am asking that we toss out pull, and attraction. I am saying the action of a force is only pressure. I say the Universe is in total motion. I describe this total motion as always being accelerative. Mankind has already tossed out the flat earth. Out went the Sun orbiting the Earth. Is there a scientist out there, that can give a good viable explanation of how any entity attracts another entity? Lincoln Barnett wrote (refer to quote below) that Einstein went with "a conditioning of Space". I like this. And, it bears out that bodies do not attract each other... but, moreover do something to Space. Note: I remember reading that Einstein said something like they just come together naturally. He used his rubber sheet analogy for these scenarios... which in reality__ does use pressure to bring spheres together, like surfing at the beach!
Most all of us know of the purported experiment of Galileo dropping two unequal sized balls from the Tower of Pisa. The balls were dropped from the same height at the same moment, and... hit the ground at the same moment. (This is disregarding air conditions and etc.) So generally when I hear people say, or write about objects being dropped__ they usually state they drop equally, or the same and etc. How many people give thought to what happens if we drop each ball, one at a time, from a specified height and point? Then compare measurements of fall duration. Did they drop equally? Try thinking in a bit more extreme scenarios. What if the small iron ball is the size of a marble, and the large ball is the size of the moon? Don't forget, gravitation of bodies is mutual. And just for fun... for these thought experiments, as Einstein liked to use... what if we drop an iron marble on one side of the Earth, and an iron moon sized ball on the opposite side of the Earth, from the same height and instant...? When thinking in this manner... we might learn to be careful how we word the explanations or results of experiments, and be careful about making assumptions, and or jumping to conclusions!?
In 1798 Henry Cavendish conducted a famous experiment of measuring gravitation by suspending two smaller lead balls balanced at each end of a rod... which could rotate, as two large solid lead spheres were brought near each small ball, one at each end. A light beam was reflected off a mirror attached to the suspension cable and reflected on, to the wall. The experiment worked , and gravitation was measure pretty accurately. Each small ball came towards their respective fixed large ball. But now, give some thought to the science of 1798__ and science of the present. What would be the general conclusion of the results back then? The balls came together; so it was assumed that it was due to gravitation, and it was assumed each ball acted on each other mutually, per their size and distance and etc. And, since they did not move away from each other__ there obviously must be some form of "attraction" of the bodies, to bring them together. (In one college physic book of mine... the word attraction is used six times in the description of this experiment... ) Excluding Einstein... I cannot recall having read very much about Space playing a part in the forces of gravitation.
In 1881 A. A. Michelson devised an instrument, called an Interferometer. This device allowed part of one beam of light to go straight, and part of the beam to reflect 90 degrees... with both beams coming back together after traveling equal distances but in different directions. As the Earth traveled through Space, and the device was faced in different directions... the results came out with both beams always arriving at the detector at the same moment. This instrument can be adjusted, and used for different experiments, but, most popular was the experiment thought to detect if there was an "ether wind." None was detected. The results, created a lot of conjecture. I have also given it thought quite a few times. If Space, consisted of some unknown ether, and there is this ether Space in, and about us here on Earth, might that space move with Earth's frame of reference, then there indeed should be no noticeable change for this instrument to detect anyway. Likewise, if Space were a void, it would also not interfere with light as the machine moved through the heavens. Also, if we ponder fields as electromagnetic in Space. They are said to not have motion, which I can envision, such as a wave has matter go up and down only, but gives the impression of progression... In the case of an electromagnetic field, its only the values that change state. And, if they change at the speed of light, since Light is thought to be electromagnetic..., again the instrument should see no difference. Lastly, I presently think of Space being occupied with Light, photons, that have the attribute of no at rest mass. The real kicker question for me: is there inactive, or inert photon corpuscles within Space? I remind you, it is now thought that when an electron drops to a lower energy level in an atom it kicks out a photon of light, as electromagnetic heat, generally. This photon is thought to be a virtual photon coming from the Space within the atom. I ask, is this photon, just created__ or does it already exist, and is only activated so to speak? And, I will mention that if Space is full of inactive mass-less photon corpuscles... they, would likewise not interfere with the Michelson Interferometer.
A lot of science has passed now for mankind. A whole bunch has changed. And, as the Universe seems to be always in a changing state, there is a lot to think about... old and new.

Anyway, along came simple carbon based life. By design, or by accident, or both, the explanation for life; is definitely out of my league, but I suspect all of us wonder about this topic at times. Then in the suspected primordial soup, or soups... there was probably chemical reactions, heat, pressures, motions, matter, and space...
Then there were beasts and plants. Following after that came mankind. I would suspect the first work done, and tools used, by mankind was hands, feet, and maybe breath. Work such as pressing dirt, as digging, with fingers and hands, to find food. Picking food from plants with pressure from between fingers, and pushing it into their mouths... These actions were work using the body. Even walking in search of food and water is work.
I suspect the very first non-body tool (or weapon) was a rock. It was possibly used to swing or throw; to hit something by impact pressure.
My guess for mankind's second inert tool, is the stick, twig, branch, stem, or log. These items I will call the rod. The rod is also a pressure device that can be used to dig, poke, stab, mix, or throw. If it a strong enough rod, it can be used to pry up rocks, or other items. Whenever it is used as a prying device, it is considered a lever. When a rod is pointed, it is used primarily as a piercing tool. Some rods when sharpened, as with a straight chisel edge, can do slicing or cutting. All these actions require pressure.
And, amazing enough, if enough rods are tied together at their centers as spokes pointing outward in assorted directions... they create a crude wheel. It can be said, a crude wheel, or maybe, any wheel is just a multitude of levers. If you draw twenty or so straight line diameters across a common point on paper... it is readily apparent that it turns into a wheel or circle. I bet you don't usually think of wheels as levers, unless schooled in physics; and even then, it doesn't get much thought. If I put enough diameters lines (rods) through a common point in three dimension, I can easily create a sphere.
To bring get back on tract... I cannot imagine any machine of mankind that does not utilize some form of pressure, and most use the lever since actions of all wheels are actually actions of leverage. Think about this... if this is correct... it means computers, drills, autos, furnaces, shovels, boats, fans, lathes, radios, phones, and etc... when really analyzed to the extreme are just using matter, space, motion, and pressure. These simple things are the natural mechanics of then... and now!
The goings on within the atom, gravitation, chemical reactions, atomic reactions, nuclear reactions, and etc., are not machines of mankind, even though we may use their actions and reactions to run our machines. Usually reactions generate Light in the form of heat. Gravitation gives us weight from water behind a dam... The electromagnetic gives us electrically generated magnetism for electricity generation, running motors, igniting lamp bulbs, and etc. But, most all of this can be equated to pressures, and the balance of actions unexplained, like gravitation, still remains unknown. However we do utilize gravitation phenomena with machines of our making, that are pressure devices. Hum...?
Physics of Auto mechanics, Classical mechanics, and Quantum mechanics all just involve pressure! Mechanics:__ Stabbing, wedging, rolling, writing, swinging, singing, hearing, accelerating, breathing, flying, eating, running, playing, repairing, painting, shoveling... etc, etc, on and on have the commonality of the reality Pressure. The Universe could not function without good old Classical Mechanical Physics Motion, Pressure, Matter, and Space to Play. I weigh heavily on: Even, Quantum Mechanics cannot get along without the classic physic's fundamentals of motion, pressure, matter, and space...
