Although we have discovered innumerable Mysteries of many many fairytales here, I don't ever recall this one popping up (and I'm praying that there's a good reason for that).
"How The Universe Works"...... on a couple years ago (Discovery Channel narrated by Mike Row (Dirty Jobs guy), Had this laugher laced through it complete with High Speed Computer Graphics.
Still graces College Textbooks!
The Nebular Hypothesis:
"Some 4 Billion Years ago, the sun had ejected a tail, or a filament, of material that cooled and collected and thus formed the planets...."
General History of Nature and Theory of the Heavens. Immanuel Kant, 1755
The Originator of this Mess met with Edmund Halley (Halley's Comet) @ Cambridge....
Emanuel Swedenborg (Originator) proffered this nonsense 21 years before Kant and Laplace. Guess where he got the idea?....by talking with spirits from Jupiter, Mars, Venus, and the Moon
Kant picked up the Idea and Laplace stamped it without doing the math (Appears they were Buddies). If he had done the Math....we would have never heard of such nonsense.
Nebular Hypothesis aficionados, have you ever heard of.... the Law of Conservation of Angular Momentum: Angular momentum = mass x velocity x distance from the center of mass, and always stays constant in an isolated system (Like The Universe we Live In). Like a skater spinning faster when their arms are pulled in close to the body. In the formation of our sun from a nebula in space, the same effect would have occurred as the gases allegedly contracted into the center to form the sun. This would have caused the sun to spin very rapidly. But our sun spins very slowly, while the planets move very rapidly around the sun. In fact, although the sun has over 99.86% of the mass of the solar system, it has less than 2% of the angular momentum. This pattern is directly opposite to the pattern predicted for the nebular hypothesis.
The Outer Planets are larger than the Inner Ones; again, directly opposite of the prediction.....
“Pssst … astronomers who model the formation of the solar system have kept a dirty little secret: Uranus and Neptune don’t exist. Or at least computer simulations have never explained how planets as big as the two gas giants could form so far from the sun. Bodies orbited so slowly in the outer parts of the solar system that the slow process of gravitational accretion would need more time than the age of the solar system to form bodies with 14.5 and 17.1 times the mass of Earth.”
Naeye, R., Birth of Uranus and Neptune, Astronomy 28(4):30, 2000
The nebular hypothesis predicts that as the nebula spiraled inwards, all the resulting planets and comets would rotate and orbit in the same direction (prograde). But Venus and Uranus rotate in the opposite direction, called retrograde.
Lucy has more splaining to do!
Retrograde Orbits Satellites/Moons: Triton (Neptune), Ananke, Carme, Pasiphae and Sinope (Jupiter), Phoebe(Saturn)
There is NO plausible Solar Origin of the Planets.
Moving on (Hopefully); something interesting: There are 3 pairs of Planets with the same Spin-Rates (within 3% of each other)...
Earth and Mars
Jupiter and Saturn
Neptune and Uranus
Unbridled Speculation here.....Were they "Brought In" from somewhere else?
More on Mars this week....you're gonna Love this. LOL
