How many years do u think it'll take to havew people live on different planets?

It would take a lot of time for a self-sufficent colony, as making the nutrients to cycle correctly would require the construction of atmosphere, tectonic plates, a completely man-made ecosystem; the planets are big, it would take hundreds of years, with nuclear technology we can only dream of... To make a science dome of some sort would take only a decade or two, the biodomes here on earth have already proven we can make a small place habitable and have no outside contact.\n\nI personally think that by 2030 someone should build a moon colony to mine the precious minerals there, the first person to stake a claim on the moon and use it properly will be the richest man on earth; it would have industrial, commercial, scientific, military, and possibly even residential interest (but they would spend their lives in a bubble).

It depends. \nIt could take anywhere from a couple of months to almost a year.

No they live on different planets

Unless we do something, life on Earth will most likely not exist once the Sun supernovas. If 'we' can figure out how to live elsewhere by then, ostensibly the galaxy is our playground. Big challenges involved though. It seems it would make sense to just move the Earth. Why not? 'we' could move the Earth, don't you think? What part of the galaxy should we move to. I'm sure we'd mostly like to stick around the Sun and it's leftovers, but we could choose to ride the Solar wind to another star. (Don't worry, humans won't have to do the hard labor of converting the Earth into a space ship with temperature and climate control). \n\nIt'll be fun. Like a road trip. Too bad we won't be alive. Probably no actual humans, either. I hope they're cool who/whatever they are.

for billions of years yet.  However the earth won't always be here to see it.

Since the universe is infinitely large, I'd say there's quite a few inhabitable planets like Earth out there. Scientists think that Alpha Centauri (4 light years) would be our closest habitable solar system. Assuming there's a habitable solar system every 6 light years from each other, we have a lot of systems to count with our infinitely large and expanding universe. We are just much too technologically challenged to get there!\n\nBTW: The sun is 8 light minutes away and it would take a considerable amount of time (if possible at all) to get to the sun using our current technologies.

No. Even if the human race moves-on to distant planets, the universe will remain diverse and we will not look the same.  \nJust watch an episode of "Red Dwarf."

the guys talking about our sun in 5 billion years are correct. by then we should figure out a way to move to a new star system.

1) Earth: It depends on how many billion years. The Sun will evolve into a red giant in 5 billion years, swallowing Mercury, Venus, Earth and Mars.\n\n2) Humans: no. Homo sapiens will either have evolved (naturally or artificially) to another species, or destroyed itself, before the first billion years.

From the Wiki,\n\n"In about 5 billion years, the Sun will evolve into a red giant and then a white dwarf, creating a planetary nebula in the process."\n\nHumans will probably be long dead before then or will have moved on.  In a few billion years, the sun will get too hot for Earth to sustain life, but it'll be a while before it finally "blows up."  More accurately, it will actually implode and slowly become an inert mass.

Yes, but not in our lifetime.  The orbit is 1,500 years from our sun to a dead sun outside our solar system.  We have a better chance of meeting helpful space visitors than planet X.

Greetings,\n\n4.5 billion more years until it swells into a red giant and engulfs Earth.\n\n-matt

Colonize in the full sense of the world, as in living there for an indefinite period of time, never, at least in those places. Not Mars or the Moon. People will live there for some periods in their life, though, but not "colonize". Too resource-consuming. Moon: 2035. Mars: 2060. Others in our solar system: 2100. Outside of solar system: 2300.\nThat of course if there's no nuclear holocaust.

yeah this world gets old and we dont know yet...it could be ten or twenty years or more....Hang in there

I guess it depends if the earth is able to sustain life before we are able to colonize on other planets or star systems.  But yes, if we are just talking about the world only as our planet, yeah, its coming soon.  It sucks.
