Joe wrote:But, they are essentially the same concept. "Gravitation" speaks to a more thorough and theoretical treatment of gravity; whereas "gravity" is common parlance for the immediate observation of gravitation. Any 2 masses experience Newtonian force, whether Earth-and-apple, or Earth-and-Sun.
Gravity is an ancient observation. Gravitation is a falsified 17th century creationist myth. They are not the same at all.
"Zero-g" is just shorthand for Newtonian force-vectors summing to 0. And, this means acceleration=0. And, in the case of gravitational acceleration, g=0. Very simple.
Zero g is a violation of universal gravitation.
Earth-Moon dynamics are well-understood using gravitational theories alone.
Well understood by whom?
"Currently, the moon is moving away from the Earth at such a great rate, that if you extrapolate back in time — the moon would have been so close to the Earth 1.4 billion years ago that it would have been torn apart by tidal forces (Slichter, 1963)." — Dennis J. McCarthy, geoscientist, 2003
"Tides are created because the Earth and the moon are attracted to each other, just like magnets are attracted to each other. " -- Keith Cooley, astronomer, 2002
"The implications of employing the present rate of tidal energy dissipation on a geological timescale are catastrophic. Around 1500 Ma the Moon would have been close to the Earth, with the consequence that the much larger tidal forces would have disrupted the Moon or caused the total melting of Earth's mantle and of the moon." -- George E. Williams, geologist/geophysicist, 2000
"Why did great cataclysms occur on Earth, such as the sinking of Atlantis and the the rise of the Andes? According to some theories, the cause was a gigantic asteroid that fell onto Earth, or the appearance of the hitherto non-existent Moon in the sky over Earth. Is this so?" -- Alexander Kazantsev, natural philosopher, 1974
"Newton’s gravitational theory is regarded as proved by the action of the tides. But studying the tides, Newton came to the conclusion that the moon has a mass equal to one fortieth of the earth. Modern calculations, based on the theory of gravitation (but not on the action of the tides), ascribe to the moon a mass equal to 1/81 of the earth’s mass." -- Immanuel Velikovsky, cosmologist, 1946
"…it does not seem likely that it will ever be possible to evaluate the effective rigidity of the earth's mass by means of tidal observations." — George H. Darwin, physicist, 1907
"…in the course of our experiments, we were led away from the primary object of the Committee, namely, the measurement of the Lunar Disturbance of Gravity…." — George H. Darwin, physicist, 1882
"...the pre-Hellenic Pelasgian inhabitants of Arcadia called themselves Proselenes, because they boasted that they came into the country before the Moon accompanied the Earth. Pre-Hellenic and pre-lunarian were synonymous." -- Alexander Von Humboldt, naturalist, 1851
"We shall commence with a few of the principal passages from the ancients, which treat of the Proselenes. Stephanus of Byzantium (v. 'Apkas) mentions the logographs of Hippys of Rhegium, a contemporary of Darius and Xerxes, as the first who called the Arcadians proselenous. The scholiasts, ad Apollon. Rhod. IV 264 and ad Aristoph. Nub. 397, agree in saying, the remote antiquity of the Arcadians becomes most clear from the fact of their being called proselenoi. They appear to have been there before the Moon, as Eudoxus and Theodorus also say; the latter adds that it was shortly before the labours of Hercules that the Moon appeared. In the government of the Tegeates, Aristotle states that the barbarians who inhabited Arcadia were driven out by the later Arcadians before the Moon appeared, and therefore they were called proselenoi." -- Alexander Von Humboldt, naturalist, 1851
"The passages in Ovid as to the existence of the Arcadians before the Moon are universally known." -- Alexander Von Humboldt, naturalist, 1851
"In the remotest times, before the Moon accompanied the Earth, according to the mythology of the Muysca or Mozca Indians, the inhabitants of the plain of Bogota lived like barbarians, naked, without any form of laws or religious worship." --Alexander Von Humboldt, naturalist, Researches, 1814
"Among the great men who have philosophized about [the action of the tides], the one who surprised me most is Kepler. He was a person of independent genius, [but he] became interested in the action of the moon on the water, and in other occult phenomena, and similar childishness." — Galileo Galilei, physicist, 1632
"...surnamed Pelasgian from Pelasgus, son of Triopas, its founder, and not far from the sanctuary is the grave of Pelasgus." -- Pausanias, geographer, Description of Greece: Argolis, 2nd century
"It is said that it was in the reign of Pelasgus that the land was called Pelasgia." -- Pausanius, geographer, Description of Greece: Arcadia, 2nd century
"After this king the land was called Arcadia instead of Pelasgia and its inhabitants Arcadians instead of Pelasgians." -- Pausanias, geographer, Description of Greece: Arcadia, 2nd century
"These were Arcadians of Evander's following, the so‑called Pre-Lunar people." -- Plutarch, historian, Moralia: The Roman Questions #76, 1st century
"The stars did not yet revolve in the heavens; the Danaides had not yet appeared, nor the race of Deucalion; the Arcadians alone existed, those of whom it is said that they lived before the Moon, eating acorns upon the mountains." -- Apollonios Rhodios, librarian, Argonautica, ~246 B.C.
The Newtonian force-law is not an equation of motion. Force, by its nature, is not directly observable. Scientists observe only acceleration, and then relate it to force. That is why equations of motion necessarily contain acceleration, and not force, as a variable.
Gravitation is said to control the motions of the heavens. It doesn't.
Electromagnetism does.
"All planets revolve in approximately one plane. They revolve in a plane perpendicular to the lines of force of the sun’s magnetic field." -- Immanuel Velikovsky, cosmologist, 1946
Total Science wrote:The moon falls away from the Earth at the rate of 3.8 centimeters per year.
So, what?
So that contradicts gravitation which predicted that heavier than air flying machines are impossible.
Just because this is happening, you conclude that gravity is a lie.
I never said gravity is a lie. I say gravitation is a lie because it is. All of the molecules in the atmosphere defy gravitation by their atomic weight.
Replace gravity with your magnetism, and now magnetism becomes a lie just as well.
Magnets have been observed to cause antigravity.
See the Levitron antigravity globe and also diamagnetic levitation of frogs and mice.
Hill Sphere?
A violation of universal gravitation.
"The ancients possessed a plasma cosmology and physics themselves, and from laboratory experiments, were well familiar with the patterns exhibited by Peratt's petroglyphs." -- Joseph P. Farrell, author, 2007
