Do you know anything about space?

[farsimon]

I ve been looking on google now for a couple of minutes and can't really find the info I need.

I want to complete the following with all the objects found in space and their relative position to each other:

moon < planet < sun < solar system < galaxy < universe

does anyone know of the top of their head where does shit like nebulae, gas giants, black holes etc fit into this picture


I hate spending so much time on research...

[SuperDavidGT]

gas giant = planet

nebulae can be > or < than solar system, depending on size

black holes would probably go with sun, since thats where the black holes come from


what are you researching for?

[TopSecretBoy]

Just out of curiosity, what are you looking this up for? I don't know much about all of that. I know a fair bit about suns though...

Well, I think there are many things in space, and it is hard to neatly catagorize them, but I will give it a shot.

Universe is of course the sum of everything we talk about. The structure of the universe is made of matter and dark matter. Some theories and observations suggested that immediately after the big bang, which is believed to be the beginning of our space-time, there were roughly th same amout of matter and anti-matter. They canceled themselves out and became light, but a slight amout of matter remained somehow, and made up all the substances in the universe. The nature of dark matter is still unknown, but they suppsedly fill the void of the bubble structure of the universe.

Everything in the universe are arranged in a bubble-like fashion. Quantum theories suggests that matters at extremely small unit do not stay at one spot, but appear and disappear fromplace to place. Some use this theory as the base of the idea of the parallel universes, but a more practical application of it would be explaining the probablity of the locations of the reappearance of the vanished matters at quantum level. It appears that the locations aren't random at all, but forms a bubble-like structure.

Bubble-structure cannot be directly observed, but it follows the pattern as a fractal pattern would, and things at most scale level follow it to some degree. It is assumed that if one look at the universe from a larger-than-universe view, one would see galaxies forming around the bubbles of nothingness. The void might be filled with dark matter, or not, but these spots are definitely vaccum, and in fact compose the larger part of the universe.

The slim amount of matter around the vaccum continues to follow the pattern, and soon the matter will bend the space and create gravity. All galaxies are formed as the result of the balance of all gravity from all heavenly bodies, while the big and small plainets form their own systems. Galaxies spin at extremely fast speed while infulencing each other. Within the galaxies. We have barbed galaxies, spiral galaxies, and elliptical galaxies. Dark matter's presence influence the galaxies, too, as the matters still follow the structure of the bubble, thus the spinnng planets and everything else in the galaxy result an inperfect shape, instead of a pefect spiral or others.

Large planets within the galaxies usually has incredible amount of mass that create such strong gravity that creates super-high pressure, which breaks down any form particle bonds and generate huge amout of heat. Under extremely high temperatures elements start to change and create nuclear fusion. All stars that we can observe in the sky are large fusion reactors in space, except the few near earth, where their reflective light was strong enough for them to be seen. Most of the planet were the result of the eventualy forge of small particles, thus many considered the gas clouds to be the origin of the planets. Many also considered the large gas cloud within our own galaxy formed all the planets we see in our galaxy. This also suggests that all planets within the little systems were also formed at the same time the core star of the system were formed, which means our sun and all the planets in solar system were probably born at the same time.

Eventually a star will burn down after it consumes all material it possess. Depends on the size of the planet, the big ones will start to convert their core into alpha and for a brief time period burning at a much higher temperature, and forcing the outter part of the stars to expand, and become a red giant. Red giants are stars at the end of its life, and usually do not last long. At the end of its life, the giant gravity field it once possess meets a violent end, and usually damages the space-time around it, forming a black hole. Smaller stars, after the red giant period, become white dwarves, and do not produce black holes. Our sun is a small star that will become a white dwarf in the future. In rare occasions, some stars will have all its particles explode before its death, thus creating a giant, bright explosion known as a supernova. Some small stars also become neutron stars instead of a black hole or the white dwarf. Since these are the product of the condensed gravity field, white dwarves and neutron stars are the densest stars in the universe. Hypothetically, there are quark stars out there, but have not been observed.

This is what I can get right on top of my head. Sorry if I can't put these things into a better order or a more technical way and terms to describe them. You can always try Wikipedia, though, if you want a more comprehensive explanation oneach of these terms.

[farsimon]

thanks yian, I've started on teh wiki and your explanation comes close...

[Yian]

Yeah... I doubt anyone could describe these thngs without professional terms, so I think Wikipedia is your best bet.

[Downfall]

i was about to sugest wiki, but it seems you already headed there.

Here's three great books that everybody who's interested in the universe should own:

1) The Elegant Universe , Brian Greene (Relativity, Quantum Mechanics, and String Theory)
2) The Fabric of the Cosmos, Brian Greene (Expands upon the previous)
3) A Shortcut Through Time: The Path to the Quantum Computer, George Johnson (Quantum Computing: a fascinating read, if you don't mind a bit of math)

Arthur C. Clarke and Carl Sagan also have some very good books about space.

I have Pale Blue Dot by Carl Sagan and it's a very interesting read...makes ya realize just how insignifcant earth is in the vastness of our universe. Here's a web site that shows a photo earth taken by Voyager from 4 billion miles away.

I also have a book by Arthur C. Clarke about how Mars could technically be transformed in the course of a few thousands years into another earth type planet...he basis everything upon science fact...not fiction. Here is a site that will give you the names of some of his non-fiction works....he has quite a collection.

A black hole is where God divided by zero.

another great book is Hitchhikers Guide To The Galaxy
