Drunkside Posted October 4, 2010 Share Posted October 4, 2010 Jupiter is still extremely far away. I mean it takes gigantic tanks of fuel just to get to the International Space Station and back. Heck, it takes quite a few gallons just to launch the shuttles. Seriously, though, space travel is still in its early stages. As Achilles stated, the difficulty in getting to mars makes traveling to other galaxies impossible at least for now. it won't be in any of our lifetimes; (that is, unless someone pulls a sheldon cooper and transfers his conciousness into a robotic body, but I digress) until the entire earth can come together and collectively work on a space project (more extensive then the ISS, a globe-spanning combined effort) humans will likely be stranded on this planet called "Earth." You do realise that when you reach space you dont need to spend fuel to move, without friction there is no passive negative acceleration which means any object with speed will maintain that speed and keep going on.

Achilles Posted October 4, 2010 Share Posted October 4, 2010 So long as it manages to avoid anything with mass (read: gravity) which might slow it down. Link to comment Share on other sites More sharing options...
mimartin Posted October 4, 2010 Share Posted October 4, 2010 Not only would you need fuel when gravity slows the craft down, but may want to a little fuel for course correction. 120 trillion miles seems a bit far to be able to fly in a straight line without something getting in the way. May also want a little fuel for when you get there and want to slow down. Link to comment Share on other sites More sharing options...
Negative Sun Posted October 5, 2010 Share Posted October 5, 2010 Also might need some fuel or technology to accelerate to near light-speed, since even at full light speed it would take us 4.2 years to reach the nearest star to us, never mind a star relevant to actually visit.

Isaac Clarke Posted October 6, 2010 Share Posted October 6, 2010 This, this, this: Show spoiler (hidden content - requires Javascript to show) Tachyons Main article: Tachyon In special relativity, while it is impossible in an inertial frame to accelerate an object to the speed of light, or for a massive object to move at the speed of light, it is not impossible for an object to exist which always moves faster than light. The hypothetical elementary particles that have this property are called tachyons. Their existence has not been proven, but even so, attempts to quantise them show that they may not be used for faster-than-light communication. Physicists sometimes regard the existence of mathematical structures similar to tachyons arising from theoretical models and theories as signs of an inconsistency or that the theory needs further refining. , and this Link to comment Share on other sites More sharing options...
Astor Posted October 6, 2010 Share Posted October 6, 2010 Shouldn't we either fix/finally destroy this planet before looking at others? Link to comment Share on other sites More sharing options...
The Doctor Posted October 6, 2010 Share Posted October 6, 2010 Shouldn't we either fix/finally destroy this planet before looking at others? This has been my sentiment ever since talk of colonising Mars started to get out of hand. Man hasn't even gotten a proper hold on his homeworld yet; he's nowhere near ready to start latching onto others as well, never mind the fact that the idea isn't yet technologically feasible.

Ctrl Alt Del Posted October 6, 2010 Share Posted October 6, 2010 Shouldn't we either fix/finally destroy this planet before looking at others? Europe sucked when they went on to colonise the New World. Link to comment Share on other sites More sharing options...
Quanon Posted October 6, 2010 Share Posted October 6, 2010 I'm still waiting for a moon base to be built Not before Belgium has a new government That might take some lightyears aswell... Link to comment Share on other sites More sharing options...
Negative Sun Posted October 6, 2010 Share Posted October 6, 2010 Not before Belgium has a new government That might take some lightyears aswell... lolz The only government I know of in which politicians are begging to get sacked. Link to comment Share on other sites More sharing options...
Pho3nix Posted October 7, 2010 Share Posted October 7, 2010 I guess the point is that It's not for us that this discovery is important, rather for the next generations to come which may or may not be able to explore it. Link to comment Share on other sites More sharing options...
