Convert them to Catholicism (or whatever other religion managed to send missionaries there first). For an interesting novel discussing missions to colonize other planets, read Stephen Baxter's book Ark. It is the sequel to Flood, but if you ignore the back story about why they are fleeing earth it can be read by itself. RE: people wondering why "super earth", it's because the planet has (substantially) more mass than earth, but still far less than a gas giant. For instance, the first one found was 7.5x the size of earth. | ||

Any scientists here can theorize a way for us to travel fast enough to where it would be relevant to explore one of these planets. We all know travelling at the speed of light is impossible. Antimatter fueled starships? i dunno..CATTLEBRUISER OPERATIONAL! | ||

1. Self sustaining soldiers 2. Tanks that can go into seige mode, like seige tanks 3. Planes with 2 rotors on each side of it 4. A plane (no matter what shape it is) that can project a drone that automatically intercepts all incoming bullets 5. While you're at it, invent invisibility for the plane 6. Maybe some planes that can heal injured soldiers Why? You ask. It is so that when the alien comes, we can do the 1-1-1 POOSH and we might be able to defend our planet with ease | ||

There are 40 known star systems within 15 light years of the Sun. Chances are at least some of them have "habitable planets". At least in the sense that the temperature and surface gravity is right. They might still have toxic atmospheres. | ||

At 0.27 AU I still think the radiation from Gliese 370 would be too intense for life to exist outside of the (potential) oceans. On September 13 2011 17:21 HaXXspetten wrote: Cool  Now how do we get over there :/ also... why "Super Earth"? lol A non gaseous planet that is anywhere from 1.9 to 10fold the mass of Earth 1 M⊕ = 5.9722 × 1024 kg. so anywhere between 1.9 M⊕ and 10 M⊕ Anything larger is referred to as a giant planet. Most giant planets will be primarily gaseous (Jupiter). Though media does use the term Super Earth liberally for flair without adhering to scientific conventions so if it's on CNN it could mean anything. Anyway, Gliese 370 is 2.11625993 × 1014 miles (36 ly) away. Don't get your hopes up for an exploration trip. Let's say we have a breakthrough in the next ten years (magic) and we can send manned ships at the same speed as probes. So that's 44 miles per second. To get to this planet it would take 249,000 years. (estimate) Sorry to be a buzz kill. 1 M⊕ equals the mass of Earth | ||

By the time they set down the nexus they'd find that we mined out the map a couple hours ago. | ||

More than 200 billions planet in our galaxy, and more than 200 billions galaxy in Observable universe.... The problem doesn't reside in knowing they are there but more on how could we possibly ever get a drone or a human on any of those planets. + As stated before, Super planets have like 4 time earth gravity so it is absolutely useless for us human to colonize such planets. The universe is awesome and I love astronomy but I'm realistic and we can only imagine what's out there until we have the technology for better observation of the planets. Traveling there is not even imaginable with our technology. | ||

Thoses planets are too far and too big. Yes, but that doesn't mean there aren't small ones out there, the small ones are just harder to detect than big ones. | ||

Traveling there is not even imaginable with our technology. It's a step in the process. The technology itself is quite amazing too: As the planet goes around its orbit it tugs the star back and forth. They can detect changes in the stars speed that's smaller than 1 m/s by looking at slight shifts in frequency of the absorption lines. That's still an order of magnitude higher than what's needed to detect true Earth analogues (i.e, 1 Earth mass planet around a star similar to the Sun in a one Earth year orbit), but it's several orders of magnitudes better than what they had 10 or 15 years ago. | ||

Science fiction is meant to be both entertaining and inspiring. All those things that do not yet exist will only come to exist by the hard work of those of our generation that decide to work hard, experiment, and innovate instead of simply wishing and waiting. Geniuses and inventors are not born they are self made with struggle and sacrifice. | ||

Let's say we have a breakthrough in the next ten years (magic) and we can send manned ships at the same speed as probes. So that's 44 miles per second. You can go ~300km/s (187mph) using VASIMR and even faster using other near term (Next 10-30 year) technologies, not to mention pusher plate type fission methods. By your math that would be 249,000*44/187=58589 years. Any trip of this distance would require a generation ship, imagine a big city like ship. That would be just under 600 generations, quite a bit. However everyone needs to realize that humans have only been attempting to think up ways to travel fast in space for the last 50-60 years much less developing and testing actual hardware. There are obviously far better methods we will come up with as a species in the not too far future. | ||
