    instead of launching rockets into space y can't you hitch a ride on a comet and fly out of the solar system...then when another comet comes along launch off and hitch a ride on that one.....?

    are we inside a star cluster?....or we just a rogue solar system inside a cloud

    is it true that you can see the first few minutes of the big bang because the light hasn't reached us yet because of the gravity that kept the light in...?

    is it true...if the universe stopped expanding then there would be no such thing as night....? and if that is true then would the mean temperature of space be roughly the same temperature as the sun?

    get back 2 you wen i think of more questions......

    thanks

    stand on the ground, jump onto a train going 300km/h and tell me how it went. Same principle, i guess

    are we inside a star cluster?....or we just a rogue solar system inside a cloud
    star cluster, also known as galaxy

    is it true that you can see the first few minutes of the big bang because the light hasn't reached us yet because of the gravity that kept the light in...?
    no, we cant see earlier than 300000 years after bigbang, not until then were light free to move around

    if the universe stopped expanding then there would be no such thing as night
    night is earth facing the other side where the sun dont shine, so we would still have night

    and if that is true then would the mean temperature of space be roughly the same temperature as the sun?
    if this were true we would boil down here, it would be about 6000K hot


    I am zelos. Destroyer of planets, exterminator of life, conquerer of worlds. I have come to rule this uiniverse. And there is nothing u pathetic biengs can do to stop me

    [/quote]star cluster, also known as galaxy

    star clusters aint galaxies...i know that for sure... unless this article is just all full of shit... http://www.sciencedaily.com/releases...0528143304.htm

    [/quote]night is earth facing the other side where the sun dont shine, so we would still have night

    and if the universe stopped expanding wouldn't there be like so many more stars we could see....therefore the sky would be bright as....therefore we wouldn't have night...


    [quote]if this were true we would boil down here, it would be about 6000K hot

    exactly...we wouldn't exist....

    not tryin ta argue....just presenting my view...

    thanks

    okey my bad

    universe cant stop expanding, it either continue to expand for ever, more slow all the time, but never stops, or it accelerates, or it stops and fall toghather again

    You would still have to get into space in the first place. Currently the simplest way to do this is to launch a rocket.
    To rendezvous with the comet would require changing our velocity to match its velocity. Currently the simplest way to do this is with a rocket.
    Thus the only advantage of this approach (and it could be a big advantage) is that you now have the resources of the comet available to you: 'fuel' to alter the course of the comet; raw material to grow food (comets are rich in organic molecules); protection from radiation and impact by tunneling into the comet.

    are we inside a star cluster?....or we just a rogue solar system inside a cloud
    We are more or less travelling around the galaxy in the company of some other stars, but they are not grouped together closely enough to be considered a cluster.

    is it true that you can see the first few minutes of the big bang because the light hasn't reached us yet because of the gravity that kept the light in...?
    Zelos has answered this. In the early history of the Universe it was opaque to radiation.

    is it true...if the universe stopped expanding then there would be no such thing as night....? and if that is true then would the mean temperature of space be roughly the same temperature as the sun?
    This is correct. Since the Universe is practically infinite then in whatever direction we look there would be a sun directing some of its light directly at us. The fact that it isn't is known as Olber's Paradox and was one of the concepts that led to the development of Big Bang theory.

    Hehe, and you are getting either closer to the sun by the minute or farther away. Either way you would be traveling to extremes, besides the fact that the comet could randomlychoose to slam into a planet. Fun fun fun...

    If we were going to the trouble to hitch a ride on a comet we would doubtless have determined its trajectory, selecting one that was headed more or less where we wanted it too.
    Rocket motors could be fitted to the comet that used cometary mass to change that trajectory in the desired direction.

    Impacts are not random, but wholly predictable. So, this turns out not to be a valid objection.
    And, of course, we may wish to have it crash into a planet: terraforming of Mars might best be achieved impacting comets on the surface to deliver volatiles, or, carefully placed on the moon to both deliver volatiles and spin the satellite up to a reasonable day length.

    Can't you put one question at one time?
    Never argue with an idiot. They will drag you down to their level and beat you with experience
