Am I the only person who finds it odd that all of the celestial bodies in a galaxy are coplanar? Or is this just a depiction on paper? If it isn't, why are they coplanar? Does it deal with the origins of the galaxy?

I have an off topic question. Are Pluto and Neptune traveling at the same speed? If not, isn't it inevitable that they will eventually collide, or does the answer to my coplanar question conflict with this question?

Well, our solar system is tilted almost perpendicular to the galactic plane--north for our solar system is actually west for the milky way galaxy. Also, Pluto is not actually coplanar in relation to the other planets; its orbit is actually a few degrees off in relation to all the other planets.

Now to the topic of Pluto and Neptune; Pluto actually travels slower than Neptune because it is a few hundred million miles farther away form the sun, and the increased distance from the sun equals decreased orbital speed. The orbital paths of the two planets, or should I say one planet and a dwarf, do intersect in two places and a collision of the two celestial bodies is a definite possibility. However, some astronomers think that Pluto could be absorbed by Neptune as a new moon during one of these close encounters.

That would be cool to see. I don't think it will happen in our life time but still that would be sweet. Going from elementary school when I was told Pluto was a planet. To know being told its not a planet. Then to be told its a moon. That would be pretty sweet.

Thank you, that completely told me what I needed to know.

i think, when the sun swells up and swallows everything in millions of years, jupiter will ignite, thus ignithing the other large gaseous bodies, and thus ending our galaxy when the same thing happens with jupiter later swells up if the next species that hopefully evolves on these next newly hospitable planets finds a way off of their rock, but that would leave several stars in the milky way galaxy

First, you spelled igniting wrong. Second, shut up.

whats wrong with that which i say? scientists have proved that stars like our sun swell up and then shrink down

Yes, they have, but that wont happen for another 5 billion years give or take a few hundred million years. So we don't have to worry about it because by then the human race will probably have populated many other systems, and will be able to sit back and watch it happen from afar.

See, I don't think humans will ever populate another planet. We have way too many destructive patterns that will ultimately end our world before we populate another. Besides, we have so many issues getting to the moon and back that I don't think we are going to find a way to get much farther.

And please don't talk like that, it gets real annoying real fast.

i agree with c73. our time in existence is limited. i'll consider myself lucky should i die before armegeddon occurs

I will have to disagree with you because we went from thinking flying was only for the birds to landing on the moon in little over a century, so I think given a few thousand years the human race will most likely be inhabiting other planet; however, this is just statistically speaking of course, but it stands to reason that with the current pace at which technology is advancing it will not be long until we have a station on the moon, and not long after that a station on mars. It is, for the most part, the natural progression of exploration that will lead to the colonization of other systems in the distant future.

i dont reckon humanity will last a few thousand years. not to sound pessemistic but we are anally raping the planet in a very very bad way (not that there is a good way) and we are running out of resources

i have to agree with a deo et rege.... but im not sure for the same reason.... here is why.. he is right look how far we have come with technology just in the last 100 years... and just in the last 100 years we have had the problem of fucking the planet up... now when did we actually start careing??? not till just a lil while ago. and we have come along ways since then. we now have 0 emission cars. we now use less plastic (look at your next water bottel) we are actually comeing along ways. now think about how far we will come in the next 100 years

Ya but we have nothing that is pushing us forward. Airplanes were not mass produced until WW1, Jets WW2, and Rockets/moon were pushed by cold war diplomacy of looking like a more powerful country (Its sad when your country has to compete for small powerful countries).

We have nothing pushing us to create the space elevator, because that is whats next. And we have nothing pushing us to create a lunar base.


Also back on to the subject of the plane of the solar system you can argue that there is only one dimension and that is Spacetime. This is according to Einstein who said that there is no up or down, but warped spacetime due to gravity. To think of it simply take a flat piece of paper or cloth and pull it tight, just enough so that it is level to the ground and does not flex on its own. Now introduce a mass to it. It bends. Creating your "up" and "down"
