I thought I just made a fool of myself trying to post this thread in a wrong place on this forum,and one of precious admins had deleted my thread and put a warning on me, LOL, I just wanted it to be more real and intense. Well, a warning is intensive enough, so, I'd better play smart this time. This is What I Replied to the admin who deleted my thread in explaining the misunderstanding: I didn't mean to raise up a new theory, but instead simply raised up a question that if it could be applied in mainstream theories, I did use the word "theory" that only because the content is quite a bit longer than usual. In this case, I only just needed help if someone could tell the content makes little sense or not. It's a little bit hard for me to originally type a lot on PF. well, since it's deleted, it seems doesn't matter anymore. My only purpose is to write a Sci-Fi story out of it, that's why I weaved up a theory as background for the story, and so the story could be more convincingly for readers,and I intended to make it eventually a short cg film. I had already gone through WiKipedia, all those information are no better than the school ones, It's becoming common sense and it would be lacking of imagination if a sci-fi story is based on those theories.Since my story's content is about the Doom's day that a Comet coming back to the Sun and affected the path of Mercury, and caused it to crush on the Sun.then it leads to human's Doom's day. and for humans had the largest plan setting up bases on Mars(shooting rockets to the Mars,setting up GPS on Mars,mining facilities, artificial moon etc. ) and eventually make it home, that's a bigger story,since the title is the first rain on Mars for that chapter. well I'm still working on it. It is currently rare to see some Sci-fi stories which don't contain elements of Aliens FTL/time travel, sub-space, ZPM, parallel universes, etc. I just want to write something that's basically based on human's own strength to survival on global disasters,and about the space travel firstly through the solar system. The original post is below: Hi, there, I'm wondering how is our solar system working. From all the information I've been taught and self-learnt from wikipedia. A theory comes to my mind. relativity of gravitation the earth has gravitational effect to the moon, and the sun has gravitational effect to the earth. which are not equal between relative planets. if the moon has 1/6 gravitational effect of earth towards earth, then the earth/moon system would be forming into a similar binary star system. and the solar system would be a multiple star system which leads to chaos. I understand that the current knowledge suggests that the sun has the most of the mass of the entire solar system, but isn't that purely based on calculations, and those calculations are based on newton's theory? so, the question is, would that theory be wrong? and then the calculation is wrong? The sun is having relative gravitational effect towards all 8 planets. and from a bigger picture, that the further ones are filled with gases and dirts on their surfaces while the closer ones are rocky.and then take a closer look at them, the Mercury seemed to be shrinking before and the sun is still burning its atmosphere out without refilling, and water patterns seems exist on Venus. Our Earth had experienced many times of volcano eruptions and earthquakes. which brought up an idea that all planets are moving towards to the sun one after another. 1,The Mercury is getting smaller and smaller, despite it is estimated billions years old, but when Mercury is young it is still Mercury,but not the same time not at the same position in solar system.Mercury could be the oldest planet currently still exist in our solar system,but it's inevitable that is going to be eaten by the Sun very soon. 2,The Venus used to be on current Earth's orbit circulating the Sun while Earth is on Mars's orbit. 3,The Volcano eruptions and Earthquakes is about to get the lighter element to the surface and the heavier elements towards the Earth core. It had been making Earth smaller and smaller,from being smaller it's getting closer and closer to the Sun. and now We could image how Dinosaurs extinction happened. It was when Earth was younger and bigger, Its surface's gravity force is lighter, and then the life form could be bigger, bigger trees and bigger animals. Dinosaurs couldn't survive from the gravity changes on Earth. partially because of the evolution of gene is irreversible. That also explains why are there so many aluminum on Earth's surface. 4,The Mars is getting more and more environmental friendly to organic life. It is a rising star that's going to be the next Earth. 5,From further gas/dirt clouded planets those clouds is getting away as getting closer to the Sun. potential test since It's because of the relativity of gravity, which suggests different elements from different planets are relatively with different gravitational force,So, the current applicable test is to get a very accurate scale, and a piece of moon rock.and a weight, made from Earth materials, that weighs the same as the moon rock when the Moon is directly above. The test is simple - weigh both objects when the Moon is directly below the tester (i.e. on the opposite side of Earth). If the theory is correct - that the Moon attracts moon rocks more than the Earth - then the change from the Moon overhead to the Moon underfoot will be a lot bigger for the Moon rock than for the Earth weight; if they're equal with the Moon above, then the Moon rock should measure as heavier than the Earth weight when the moon is directly below. (it's an idea, not sure if it works) Raised questions 1, How do you explain Pluto? It's further out than the rest, and rocky. A:Pluto is in a very far distance, the Sun could not heat it up yet as it currently remained that way. the whole gases turning into rocky planets is an idea about how heavy elements get closer to the planet's core while the lighter elements getting to the surface. It would be more like a self-stabilizing process and it only works relative to the sun's gravitation force and heat.it is easy to see those standing-by products being in the waiting position in a automatic processing line. 2,But we can tell what elements are present in the different planets, using spectroscopy. So we know that Jupiter, for example, is mainly hydrogen and helium, not just dust. A: Using the spectroscopy could only estimate the elements on a planet's surfaces not to mention Jupiter is currently heavily clouded. from what We know, hydrogen and helium are very light elements on Earth.and if spectroscopy is really that amazing, then it might be not that hard for us to find goldmines on Earth. 3,It is known that Jupiter's gravity is a lot stronger than Earth's. A:yes it is, for itself and its own moons. but It is possible that Sun's gravitational effect towards earth might even be stronger than the Jupiter's. and another assumption is that Sun's gravitational force has an un-equivalent linear level. 4,But the weight of an element can be found by adding up the weights of the protons and neutrons and electrons that make it up. A proton isn't going to change weight by being in a different element. A:The weights are gravitational effect towards the core of Earth.I don't know if there's anyone ever did that experiment to weigh a proton.and is it weighed on Earth sea level? but that's totally another story since I'm talking about elements here,there should be more elements out there,some of them are heavier and some of them are lighter. 5,Why would the Earth be getting smaller? every now and then, We get a meteor landing-wound't that be making Earth bigger? A:From the heavier matter(elements) goes down and the lighter matter(elements) gets above,every planet should be getting smaller and smaller as long as it's staying with the Sun.Meteors would be very slightly increasing the time in a planet's getting smaller process.ever seen a cooking vegetable process? you're adding salt and other materials to it but doesn't stop it getting smaller. In this case, Meteors are like salt you put on vegetables. 6,And the sun's gravity affects the moon's orbit as well, And both the Sun and the Moon have a gravitational effect on Earth(i.e.tides). A:Yes, they do relatively affect each other, that's why I brought this relative gravity idea up in the first place. 7,Actually, the moon's gravitational effect on Earth is stronger than the Sun's. Consider; high tide depends on the position of the Moon, not the position of the Sun. The Moon's tides are higher than the Sun's tides; therefore the Moon has a greater gravitational effect on the Earth than the Sun does. A:Not really, if the Moon's gravitational effect on Earth is stronger than the Sun's then, it would be Earth going around the Moon a little bit too, forming into a binary star system. Since it is only the moon going around Earth, and the Earth is only going around the Sun,and the Sun is probably going around something bigger. and then,I can only assume that the Moon's gravitational effect on Earth may not be stronger than the Sun's, It might be the Sun's gravitational effect on Earth appears to be constant, The Moon just changes it while circling Earth, and We could only observe the changes. It took me quite a while a weave something like this, Could anyone in this field please advice me with professional knowledge, thanks in advance. Your name will be mentioned on the list(only if allowed) as science advisor if I'm able to publish it a book or a short CG film. (I'm only a hobbiest photographer and writer, I can only do these kinds of stuff using my extra time.) Please keep in mind this is only a sci-fi story's back ground, I have no intention nor do I have the ability to establish a real theory out of it. Regards Lee Many Thanks!!!!
