Re: EU's Method for Earth Formation
I believe that previously the thunderbolts team were careful to not suggest definitely how the earth and other planets were formed, for various reasons perhaps including:JeffreyW wrote:I have searched Electric Universe for over 3 years now and have not found anything that addresses the formation of the Earth.
Firstly mainstream science has shown that once you have a theory everything you then find is forced into that theory, so you do no seem to evaluate empirical evidence properly.
Secondly we were not there when they were formed so how do we really know what happened? We may have ideas but they are only guesses, especially at the moment when the EU theory and evidence has to piggy back on mainstream science experiments and observations.
From what i understand the Expanding Earth theory was (is) not part of established Electric Universe theory canon. A few TPOD articles have investigated it The Expanding Earth Debate - Part One and The Expanding Earth Debate - Part TwoJeffreyW wrote:For those who state things such as
2. Expanding Earth
2. What mechanism creates matter out of nothing in the center of the Earth?
It depends on what you mean by "nothing in the center of the Earth?" The Earth may be hollow like a geode but for it to have nothing would imply a proper vacuum which seems unlikely and i guess you are not meaning that?
If the earth is hollow perhaps it has plasma inside that may create material? Perhaps the mass comes not from the center of the earth but from near its surface - volcanoes and mid ocean ridges producing 'new' mass?

Jupiter's migration key to our unique solar system
Tuesday, 24 March 2015
Stuart Gary
Earth and the other terrestrial planets are late arrivals, forming only after the original planets of the inner solar system were destroyed, according to a new model explaining our solar system's unique architecture.
The study reported in the Journal PNAS, tries to explain why the solar system looks so different from all the other planetary systems scientists have observed so far.
"We are more or less a galactic anomaly," says the study's lead author Dr Konstantin Batygin of the California Institute of Technology.
"Systems like the solar system are a minority, so when we ask ourselves how common are 'truly' Earth-like planets, with Earth masses, hard surfaces, and small atmospheres, the answer is they're not very common at all."
The new model by Batygin and co-author Dr Greg Laughlin of the University of California Santa Cruz, shows the terrestrial planets Mercury, Venus, Earth, and Mars, must have formed hundreds of millions of years after the Sun and the rest of the solar system.
"They were forming when there was no more gas around, which is why we have a rather clear atmosphere, in sharp contrast to extra solar planets that we observe," says Batygin.
The inward planetary migration of Jupiter early in the solar system's history may have been responsible for this anomaly.
Why are we different
Batygin and Laughlin saw that about half of all planetary systems orbiting Sun-like stars feature large populations of 'super-Earth' sized planets which are thought to have substantial gaseous atmospheres.
The authors also noted that these planets were on orbits far closer to their host stars than the 88 day orbit of Mercury, the nearest planet to the Sun.
"If the dominant mode of planet formation is one that produces super-Earths on short period orbits, is it natural to assume that such planets existed in the early solar system?" asks Batygin.
"If so, what happened to clear the inner solar system of these first generation of planets?"
Batygin and Laughlin developed a model showing how the inward planetary migration of Jupiter early in the solar system's history would have triggered the destruction of all the original planets of the inner solar system.
The authors found that the gravitational interactions caused by Jupiter's journey, sent the solar system's original inner planets crashing into each other, causing them to smash apart, with the resulting debris falling into the Sun.
Then, the formation of Saturn, caused a gravitational interaction which drew Jupiter back out again to its current orbit.
"When Jupiter and Saturn move in and then out of the inner solar system, it initiated a collisional cascade in the inner solar system," says Batygin.
"As it moves inwards, Jupiter would have picked up about ten Earth masses worth of planetesimals along the way which would have been crushed due to collisions among the planetesimals."
A new beginning
Over the following hundreds of millions of years, the small amount of material left behind from this catastrophic event, coalesced to form the four small terrestrial worlds of Mercury, Venus, Earth, and Mars.
"This explains why the solar system's inner planets are so small and contain such thin atmospheres, compared to those seen in other planetary systems," says Batygin.
The Jupiter planetary migration hypothesis was originally developed to explain the structure of the asteroid belt, why Mars' mass is smaller than that of the Earth, and to understand the distribution of bodies in the outer solar system, including the orbits of Uranus and Neptune.
"We were not focusing on Jupiter and Saturn's early migration, we were interested in what makes the solar system unique, but it turns out Jupiter and Saturn's migration was the answer," says Batygin.
"It's very satisfying to have arrived at an idea which has already been proposed to explain other features of the solar system."

Re: Sounds like a wedding
So we are now back to the "Earth Solar System is unique" all over again then.
Sheesh or what!!
The only reason it seems this weay is because we have not been out & had a look at what is really happening - I seriously doubt there is anything special about our solar system at all. It's an ordinary star like trillions of others - nothing special, nothing unique.
I suspect that other systems so far seen simply are either
A - younger than ours, or
B - so far away the light reaching us is much, much older.
Incidentally, there is no valid mainstream theory of how the planets were formed in the first place - accretion from dust clouds does not stand up to scrutiny, and if anything systems with the large planets near their star makes sense as a new system we are only now seeing that will look nothing like this if visited as light takes time to travel to us.
These gas giants are close to the parent star that ejected them because they are new and on the way out - not because they are old & on the way in. As usual, the mainstream has it all back arsewards.

Well if the universe is infinite, nothing is unique, right?So we are now back to the "Earth Solar System is unique" all over again then.
Does this sound right? A planet is measured, in comparison to its host star? If measurements of distance and consequently size are incorrect, wouldn't the planets have the same problem? Since the star is presumed to be further away than it actually is, it is presumed larger, and hence the planets are presumed larger?
Unique? I think every star system is going to have its own character and story, I don't think we will ever find a star system that feels just like home, we can find something close though.

Planet Nine?
http://www.nytimes.com/2016/10/21/scien ... -nine.html
"Most people think the eight planets in our solar system orbit the sun along a straight plane, like a disc on a record player. But actually, that plane is slightly tilted, and now astronomers think they know why: The elusive Planet Nine.
"Earlier this year Michael Brown, a professor of planetary astronomy at the California Institute of Technology, presented evidence that there may be a massive planet beyond Neptune orbiting the sun. The so-called Planet Nine is thought to be about 10 times the mass of Earth and about as large as Neptune. At its farthest point it is about 155 billion miles away from the sun.
"At that size and distance, this planet’s mass would have large effects on the other planets orbiting the sun.
“It’s so far away that it essentially gets this huge lever arm on the solar system, and it slowly tilts the planets in its direction,” Dr. Brown said Wednesday during a joint meeting of the American Astronomical Society’s Division for Planetary Sciences and European Planetary Science Congress in Pasadena, Calif. “It can tilt the solar system.”

Re: Planet Nine?
Well, as it it obviously turns out, the planets don't rotate in a flat plane, or in neat circular orbits, but in eliptical orbits that aren't flat. This is part of the description that is left out of the text delivered to the public. Now why is that?

Re: Planet Nine?
As far as I know, once matter gets trapped far away enough (but not too far) from a core like a star (our sun), or the core of a galaxy, or the core of a planet like Saturn, it goes into an orbit - not collapsing with the core, nor escaping the elliptical path. These objects are then directed to the equatorial plane of the core, whether that be the core of the sun, Saturn, or the core of the milk way, that is where the highest rotational velocity takes place, and purely by rotational (centripetal force or whatever), the objects gravitate to that plane. In the case of saturn, small rocks or w/e rotate in different directions in this equatorial plane, collide with one another, release debris, and the debris make up the rings of Saturn (from previous collisions of rocks!)
This is a process, it doesn't happen instantly, so if objects are still orbiting far off from the equatorial plane of some core, you can bet that it hasn't had the time to gravitate to the equatorial plane yet, but is in the process of doing so. Or, maybe something knocked it out of a more stable orbit and altered its orbit, but basically its a sign it has been disturbed recently.
The milky way obviously has a spherical core (no core is a perfect sphere but its an approximation), and a disk like structure as you look outside the core, same for saturn, or any core, the faster the core spins, the stronger the centripetal force. If you don't have a strong spinning core, like in the case of 'core-less galaxies', which are just fragments from past galaxy collisions, you don't really get the disk-like shape anymore (although the center of mass of that galaxy will function as a weak core itself, it is very weak).
The most undisturbed, ancient galaxies are ring galaxies, and in my opinion are the most badass galaxies too. They represent the final shape of a galaxy if it's left alone (no collisions or major disturbances) for a long time.

As you may notice - there is a secondary, MUCH SLOWER effect - matter gravitates away from the core due to the circular motion to make a 'ring' or band, like we see on Saturn. The milky way hasnt done this yet, its not old enough.

Re: Planet Nine?
If they find planet nine then what if is cometary. A very elliptical orbit. And then trace it's orbit backwards to, say, 12,000 years ago. I agree that the angle to the ecliptic is a sure sign of pretty recent activity, rather than this planet nine being out there for millions of years.
And once you have planetary orbital shifts then that opens pandora's box. Plus the evidence of fruit salad stellar planetary systems leads to a revolution really. One has to answer the question of how, Venus, say, could undergo an orbital shift. Even if this requires a Solar System wide event, like a galactic superwave.
Do Neptune size planets fire up outside the Solar System magnetosphere. Or are they cool which means there might be absolutely untold of these planet 9 size objects out there and we do not see them just as we have not seen planet 9.
The Planet X people must be bursting !
Cheers,
Mo

Re: Planet Nine?
Correction: Planets revolve (travel around) around a central point; they don't "rotate", which is to turn on an axis. "The Sun rotates on its axis, while the planets revolve around the Sun as they rotate on their axes."kell1990 wrote:Well, as it it obviously turns out, the planets don't rotate in a flat plane, or in neat circular orbits, but in elliptical orbits that aren't flat.

Actually, the planets (and the Sun to a minor extent) trace a spiral through space as the Sun moves through the cosmos. It just occurred to me that if this is so, then how can the planets have formed through a process of aggregation? Wouldn't all the assorted mass be strewn behind the Sun, like a contrail behind a jet engine on an airplane?

Another age guess for planet earth?
I have no idea how they could find out about this.
Is this from another imaginative paper theory from the mainstream Mensa group.
"(Dust) particles larger than (about one 100,000th of a centimeter in diameter) form a large disk-shaped cloud that orbits the Sun between the orbits of Venus and the asteroid belt. (This cloud produces zodiacal light).Forces acting on these dust particles (called the Poynting-Robertson effect) should spiral most of them into the Sun in less than 10,000 years. Known forces and sources of replenishment cannot maintain this cloud, so the solar system is probably less than 10,000 years old)".

Re: Another age guess for planet earth?
Interesting. Sounds like the age of Venus, and the cloud is between the orbits of Venus and the asteroid belt.
But if one is constrained by the straitjacket of the nebular hypothesis, then Venus must the same age as the rest of the Solar system, which we "know" is 4.5 billion years old. I've read it lots of places.

Re: Another age guess for planet earth?
Good find, Bomb20, but can you contest it? Simply calling it "creationist" does not invalidate it. I first learned of the Poynting-Robertson effect from Tom Van Flandern's writings. And although Wikipedia is a standard-bearer for establishment science, they have an article on the mechanism, too. So I'll consider Poynting-Robertson a given for now.Bomb20 wrote:It is creationist stuff, see: http://www.creationscience.com/onlinebo ... ces52.html
What I want to know is: Is the "zodiac light would have dissipated by now" argument valid? There are similar conundrums in planetary astronomy:
- • Titan has a fraction of Earth's gravity, yet has an atmosphere denser than Earth's. Possibilities include: Titan is a young planet, which would throw a monkey wrench into the nebular hypothesis; or something other than gravity holds atmospheres to celestial bodies; or there are hidden (underground) reserves that keep venting and replenishing the atmosphere. The latter is the establishment's default position, as with dark matter, cometary ice, and—
• The Oort cloud is an imaginary reservoir of dirty snowballs halfway to the next star because otherwise all the comets would have evaporated by now.
• Venus is similar to Titan in that it pushes extremes that cannot have lasted for 4.5 billion years. So untenable models, like "runaway greenhouses" are dreamed up to preserve the status quo.
The point is, could the zodiac light dust be a transient and "young" feature of the Solar system? Step out of the nebular hypothesis, which is a straitjacket requiring everything to be the same age.
