What technologies do we have that will get us to a habitable planet?

Based on the relativity theory, there are many studies that are taking place to look into the possibility of traversing the time-space continuum.  As far as I know, we're not quite there yet.  But if and when we are, we should be able to tap into the theoritical "worm-holes" to go into different points in space without having to exume too much time.

It will happen someday. I dissagree casually with the people who said it will never happen. I believe once we have a cheaper energy source, and faster travel, we will do it. \n\nWe have the technology today, but it's the cost, the danger, and the time that prevents us. \n\nIt will happen someday, I have no idea when, but it will. I wouldn't hold your breath though.

While I agree with other people here that we should take better care of our planet, eventually the Earth will be destroyed.  Even if all comets and planet-killing asteroids miss us, the sun will eventually expand into a red giant and engulf the Earth.   Though that isn't likely to happen for possibly another billion years, it will eventually happen.\n\nThat being said, the more planets that we as a species inhabit, the greater our chance of survival.  Especially when we consider the possibility of colonizing other worlds in distant solar systems.  The endeavor will not be an easy one, and is indeed not possible at our current level of technology.  However technology may eventually advance that allows us to traverse great distances of space in but a few moments, perhaps through the creation of artificial wormholes.  Maybe we'll be lucky enough to see it in our lifetime.

divert a huge Ice Comet into the planet?\n\nOr truck a metric butt-ton of hydrogen and oxygen there (frozen of course to bring the most amount in the smallest space) and burn the hydrogen with the oxygen to create seas of nice H20

We are developing technolgies at a rapid rate e.g. computational power increases by almost a factor of 1000 every 5 years. However, I dont think we can achieve faster than light speed travel in 50 years (partly because its not physically possible, according to Einstein) We would need a great deal of energy, as someone mentioned before, the power of a 100 suns. We are currently a Type 0 civilization, harnessing our energy requirements from fossil fuels. It would take a lot more than 50 years to achieve near to light speed travel.\n\nHowever, there are concepts which have been put forward that are a step ahead in space travel, like the Hydrogen Ramjet. This vehicle can possibly travel at 30% of the speed of light although it requires a miracle in terms of engineering

dude above this comment addressed some of the problems . . . but what about the solutions?\n\nFor my astrobiology class I did research on terraforming Mars, and learned quite a bit.  The first thing that would need to be done is landing, constructing miniature chemical fixing plants that could do to the atmosphere exactly what we're doing to this planet right now: release greenhouse gases that otherwise would be locked in the regolith. This would have to be done first to allow the planet to warm up a little bit, but this would take a few hundred years. You see, this would project would have to have the full commitment of the entire human race over a few thousand years for this to be "completed."\n\nAfter a few hundred years of warming,  you might actually outgas enough atmosphere from the regolith to hold liquid water stably, you might have a little more CO2 to build atmos. pressure, but growing algae or anything would require genetic engineering, since algae, im sure, is not going to grow in soils containing peroxides and epsom salts. They would fix the atmosphere to contain more oxygen. This would also take a few hundred years as well.\n\nAssuming we had the patience for this, we could have some sort of atmosphere close to 60% the pressure of ours within 600 years, and the temperatures from the 50s-70s (one scientific paper said something about 77F being reached feasibly). So this terraforming is do-able, but do we need to? have we finished discovering things on Mars before we start erasing it with running water and weather systems? \n\nSome say there is still a lot of water on Mars, enough to make an ocean covering the entire planet about a few feet deep (thats a lot), but that would take a lot of work to achieve.  Also, you have to realize that all this work would not be permanent.  Mars has no magnetic field, and thus no real protection from the solar wind which would slowly strip the planet of its atmosphere. \n\nthe "mars project" would be fruitful but not permanent, and would work for probably a good several millenia, but would need maintenance. . .  \n\nim done typing

I hope so...\n\nI would like to imagine a future of space travel for the human race.\n\nBut I have no expereince in the field to offer suggestions.

Not a this point in our evolution......we do not have the technology to build something that will protect us from the hot temperatures\nof the inner earth.  Your question is puzzeling, am not sure what \nyou have in mind.

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).

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.

they could come from other star systems and yes they would have the technology to travel to our world. the universe is estimated to be around 12 billion years old.\n\nhow long have we been on this planet?\nwhat was our technology like 200 years ago?\n...no electricity, cars or planes etc.\nlook how far our technology has advanced in 200 years...\n\ncan you imaging what technology the aliens would have if their world started a million or billion years before ours?

Yup. The latest will be 5 billion years from now, give or take a few hundred thousand. By then the sun will either:\n\n1) engulf our planet (very unlikely, but will come close enough to vaporize our planet)\n2) Die and not engulf or vaporize our planet and within days our atmosphere will freeze and fall to the earth in the form of ice.

HOW TO LIVE ON planet earth WITHOUT decimating it !

Virtual Reality - almost there so this is most likely.\nBrain Transplants are currently too tricky.\n\nAlien Encounters would be cool - this is what I would like most. It would make veryone on Earth get along a bit better.

No other planets are habitable for humans.\n\nMercury and Venus being far too hot.\n\nJupiter, Saturn and Neptune for being gas giants and so has no solid surface. The gravitational pull of these planets would crush our bodies. Juipters gravititational pull is over 300 times the earth.\n\nPluto is too far away thus seeing temperatures of over -200 degrees C.\n\nMars would have been a perfect candidate, as the temperature is quite similar to earth's at occasion. But our lifes need plenty of water and the abundance of water on Mars is basically zero.\n\nFor other life than humans, a moon called Europa, which orbits Saturn, contains frozen methane and water, which could harbour life. The only problem is its a moon and not a planet.\n\nThere are all the other planets (approximately 250 so far discovered) in the Keiper Belt which need to be examined

Life on other planets is possible. Think about the billion other planets out there. Scientist have discovered that there are other planets capable of sustaining life, even if there weren't, plants can grow in space, therefore ecosystems can be built on other planets to produce oxygen. How long will it take us? As long as we realize we are all humans and we stop fighting over oil and money.

No we dont have the technology yet
