“The inertia of any system is the result of the interaction of that system with the rest of the universe. In other words, every particle in the universe ultimately has an effect on every other particle.” – Ernst Mach, Mach’s Principle of Inertia (1893)
You are in either Bonneville, Black Rock, or perhaps Al Jafr. Pick one. While meditating on the desolation, you assume that space is merely emptiness. An absolute void. The desert merely nods in the affirmative.
Your inference is wrong. The desert lies. You are not the first to be hornswoggled by such supposedly empirical observation…
Ernst Mach – the man who uncovered the mystery of the speed of sound – was an empiricist and a logician. A logical positivist. He presupposed that space is merely emptiness. The Void. The Quantum Vacuum. He was wrong.
Space is loaded with stuff that won’t glow in the dark in any way that astronomers can spot.
This stuff is loaded with a so much mass that its gravitational field tugs and affects the velocity of everything else in the universe (including Land Speed racers).
Even though the mathematics of the day insisted upon the presence of a form of mass that instruments could not and (cannot) detect, Mach insisted that space was empty. If you couldn’t see the matter within the space, nothing was there. (He also insisted that the atom existed only as an abstraction, but that is another riff altogether and tangential to this one … )
Space has to have mass for inertia to tug on heavenly bodies. It takes the form of dark matter. The Mach Principle states that inertia depends on the reciprocal interaction of bodies, however distant; in other words, a body in motion tends to stay in motion unless acted upon by another force.
Dark matter is stuff the cosmologists of Mach’s day could not see; suffice it to say there is enough gas and dust that the vacuum as a condition of complete and absolute void does not exist.
Despite what the physics and the math of the day indicated had to be there, Ernst Mach made no never mind for the stuff in between the heavenly bodies – a pretty big snafu, cosmologically speaking.
Not even Einstein was able to suss out the Laws that truly guide (and guide us through) the Cosmos…
Dark matter: The entropy and chaos of the cosmos… Its presence was undetected, yet its gravitational pull tugs on all things. It is entropy that guides us, and it is entropy that acts as a force that slows us down… entropy equals inertia, and entropy is a force that acts counter to the infinite… and yields the finite…
The devil lurks in the entropy that tugs on our every thought and action like so much dark matter; he lurks in the banality that is Life on Planet Earth.
Yes, “every particle in the universe ultimately has an effect on every other particle.”
Specks of dust and pockets of gas gravitate towards a darkness so black we cannot see it and whose magnitude is so massive we cannot come to terms with how to measure it. The stuff we cannot see and don’t know how to measure made Einstein blink and made Ernst Mach draw a line in the sands of epistemology.
Ernst Mach is synonymous with “inertia.” But his own tug and resistance was not gravitational, it was intellectual.
The desert bleaches everything white as stone. It is a blank slate, according to a friend of mine who used to work in a junkyard. What the empiricists call “tabla rasa.” On a meta-level, perhaps my friend is right. The desert rarely puts up an argument. But it ain’t empty. And it puts up more resistance to human endeavor than the pull of a dark star on a cosmic body or spaceship set on warp speed.
By extension, a blank slate is perfect tableaux upon which one can foist his dreams. It is the perfect setting for the Land Speed Record. It is also the perfect setting for failure.
