i have 1 thing to tell you brown dwarfs are stupid. the asorid belt is a planet that failed to form and pluto.. mabye its a large comet passed bypluto and alter its orbit
if black holes can move mabye a tiny 1 appered near that wat is now a belt.. it ripped the planet or planets(theres a lot of rocks lol) and it disappered and somthing like that

I mean a BIG damn star that can provide enough light and heat for a whole planet you "stuff i cant say here"! Do you realy think the normal stars can provide a whole planet?
And yes i know there are planty more stars out there but have we found any as big as our sun ? = NO!
actually, our sun is an average sized star. there are stars like 1,000s of times bigger.
mathal whatever, just because something is beyond your ability to comprehend does not make it stupid. and no, black holes cannot move like that. all they can do is drift around due to the influence of the gravity of every other star out there. and i am almost certain that pluto was in fact a moon of neptune at one point in time, just look at its orbit
venom, spellcheck please. and as dumb as you think everyone else's theorys are, yours you just stated are worse. how do you know life on earth is just a "fluke" and hasnt happened elswhere? have you ever been to space yourself? i am guessing your 2nd "point" was supposed to be sarcastic since it totally went against your first, but again, how do you know there arent aliens studying us? and i am sorry, but if that cloud "theory" had anything in it that was actual fact, dont you think it would be on the news like all the time?

We better get this stuff right because, from what i heard the sun is going to run out in 500,000,000,000years(5billion). then i guess the sun will comsume the solar system. idk my science teacher might just be on acid.

i thought the theory was that our sun would probably supernova when it runs out of energy

Oh and just to clear up guys, somethings density doesn't determine its gravity. it's the object's mass. sure if it's dense it ussually has more mass, but it's the mass that determine's gravity. There's a galaxy in oryan's(oh-ryan's the men in black one) nebula that is almost like a vaccum(no matter what-so-ever) but is thousands or millions(not sure) times bigger than ours and have tremendous gravity i think. and as to the super death cloud thing, i think it's total bs lol. sounds like a tabloud story.

your right, it is mass that causes gravity. i was talking about density because brown dwarfs are very small.
orion is a constellation, not a nebula. and all of space is a vaccum. vaccums are the only thing in the universe that DOES NOT have gravity, because theres no mass in it. i think you are trying to talk about a galaxy

this refers to an older post, but really think about it. nuclear power plants are near our homes, planes fly over us with neuclear bombs, and ships have neuclear reactors. if people actually realized this, i think there would be no problem equiping a spaceshuttle with a necular engine. (how do u spell nuclear? i think i spelt it 3 different ways in this post.....) and obviously we have good enough sheilding technonogy to protect the crew and their offspring from radiation, or else our navy would be full of mutants  but anyways, the biggest problem would be getting the ship out of the planets atmosphere, thats why they should have it shipped up in seperate pieces, then assembled in space. there, problem solved. at least in my mind

on the topic of the our sun going supernova:
it's predicted that when it becomes a red giant, its surface will actually expand past earth's orbit and consume the first three planets. however, mars will still be far away enough and the sun's expansion will actually provide the heat and warmth that earth used to have, hence our interests in mars to be a future colony

ok the thing about gravity being about mass, a black hole (a VERY dense material) is pretty small, so would have to have a very high mass. (ive heard a tablespoon of it would comsume our planet earth)

It would be longer than 20,000 years. A half-life is exactly what it says it is, the life of half the radioactivity. I'm sure even half the amount of radioactive material they bring along is enough to keep them going.

actually gravity has everything to do with density because density is the amount of mass per unit volume..in other words density is directly related to mass..and thus the more mass u have the more gravity u have
for example u cn have to planets the same size but 1 is highly more dense then the other and u get more gravity...
so black holes are a single point mass to explain why they have so much gravity is that they have so much mass in a very small space and thus its highly dense
therefore yes density has a lot to do with gravity.

no because look at a gas planet like jupiter. It's made of gas with makes it not very dense, but it had tremedous gravity.

because it is huge for a planet. its not that dense, but it has a hell of a lot of mass. mass is what gives gravity. high density usually means high mass, but not always. so high density usually means high gravity, but not always

if our sun is a red gaint mars cannot support life it will burn up and become mercury lol saturn has less denity than water but it has alot of mass so...
i think our sun will consume all four of the planets so pluto is our only hope its cold but we'll live plutos orbit IS strange ur right about pluto, moon of neptune.. mabye some comet say...65 million years ago altered plutos orbit and destoyed the dinosaurs...2 in the price of 1 lol..
urianium a product of nuclear has a halflife of 892 years or somthing i lernt that from grade 7 (second year of grade 7).
...what the hell is with points?? i thinks its going down
hey 100 posts! yay

i really wish you would stop posting...your posts frustrate me so much with their lack of intelligence. currently, pluto is close to -400 degrees fahrenheit. ''its cold but we'll live''? mars will become mercury? wtf? and obviously saturn is going to be less dense than water because water is a liquid and saturn is mostly gas.

no i meant pluto in the red sun days ..it might go to -20 max
mars will get hotter and hotter thus mercury type no atmosphere
i have a huge head ache so stop teasing me
hey the points went up

do you always have a headache when you post? because its not just today...
anyways, perhaps you werent aware of this, but red giant stars produce far less heat and light than average sized yellow stars like our sun, even though they are much bigger

and mars is also a lot farther away from us than you think. when the sun becomes a red giant, it's going to be the new earth
