    its hard to read there, but great for hunting in the jungle

    "This newly discovered planet is just 22 light-years away. Its discoverers are calling it the "new best candidate" to support water, and possibly life. The planet's unique features could even make it the ideal home for creatures like the Predator.

    The newly discovered planet, which has the rather catchy name of GJ 667Cc, is at least 4.5 times the mass of our planet, and it orbits its host star every 28 days. While that may not sound anything like our planet, the fact that it orbits a much dimmer red dwarf star means that it ends up getting about 90% of the sunlight we get on Earth. But most of that light would be infrared, which would allow the planet to absorb more energy than if the light was in optical wavelengths.

    That places the planet comfortably in the habitable zone of its host star — but it also raises some intriguing possibilities about what the nature of life on this planet. Life on our planet evolved to see primarily in optical wavelengths because most of the light that gets through the atmosphere is visible, while other wavelengths like ultraviolet and infrared are absorbed by the ozone layer. That's especially true of the oceans, where vision initially evolved hundreds of millions of years ago, as the water tends to block out everything but a very narrow band of optical wavelengths."

    4.5x the size of earth? Unless its made of polystyrene, the gravity there will be hella strong, so it doesn't matter even if we could get there via some sort of Lost In Space type cryogenic stasis ship, even if Matt LeBlanc was the pilot.

    You are making the same error as that 19th century philosopher, whose name has now slipped my mind, who tried to come up with a question that could in principle never be answered. His example of such a question was "What are the stars made of?" Within a few years after he posed the question, it was answered.

    Within the next few decades we will probably have the necessary technology to take a spectrum of such nearby planets. If they have life on them the spectrum will tell us so, in at least some cases. Who knows what else we may be able to find out about them without necessarily having to go there.

    The philosopher who used the composition of the stars as example of an unanswerable question soon had egg all over his face. And now we have here a philosopher who uses the nature of extra-solar system planets as example of "pointless information." He couldn't be more wrong: astronomy has always been, and remains, one of the most fundamental pillars of all science.

    It depends on the size of the planet. It might not be very dense, in which case the surface gravity may be bearable. Perhaps there are short and stocky Predators living there. If they then come to earth for the hunt, they'll be able to perform quite astounding-looking physical stunts. :-)

    It would have to be somewhere in the region of four times less dense that the density of the sum of all the things our earth is made of, which is super-unlikely. It would likely be uninhabitable for humans, was all I was saying

    Could perhaps be if it is made mostly of water?

    Such questions may well be answered in the coming decades, when we develop better technology with which to image the planets directly.

    other people have already pointed out this is a stupid thing to say for several reasons, but it might also be practically untrue.

    I mean, ok, sure we are no where near launching a big tin can full of humans, with all the pluming necessary to keep them alive, to another stellar system.
    Frankly I think such ships probably wont happen for thousands of years, if ever.

    But what about a tiny starship the size of your thumb, full of ultradense cimputers, some smart matter, a big mesh mirror and a signal laser? You could drive it using a big laser in orbit around the earth so it wouldnt need engines.

    Such a device might carry very smart AI's, or even fully digitised humans in the comfort of simulated environments, to nearby stars within the next 200 years..

    You have no sense of importance or history. If every discoverer or inventor said that we don't need to discover or invent because it won't affect me now you wouldn't be sitting on your lazy ass enjoying the fruits of other peoples' labors.

    If the planet itself was made mostly of water, it wouldn't be similar to earth, but if you mean the % of its surface covered with water, it wouldn't make that much of a difference overall, but you're right, there's loads of things we wont know without more advanced technology.

    "even if they made a ship that could make the journey. It would take so long it's not even relevant to us."

    22 light years at 25% C is 88 years, plus another 88 for signals to get back. 176 years years. A long time to you and me, but to people the people of 2300AD who might live for 10,000 years its cool.

    the big problems with space travel are journey time and hauling all the crap that meat humans need to live.

    IBut if your just pushing computer substrate, the ships can be tiny, and if all the crew are uploads, the plumbing is eliminated. Real humans could well travel to other stars, just not in the big wet bags of meat we call bodies.

    Its entirely plausible to colonise the entire galaxy with a sublight upload culture in maybe a million years, a very short time in the grand scheme of gigayears and gigalightyears.

    Even more spculatively, a great way to colonise a whole universe might be to go back in time and inject ones whole culture right after the big bang, and then let cosmic expansion do all the work. the fact that no ones seems to have done this suggest its not possible though.

    Actually, only 22 years for the signals to get back, as I'm sure you know.

    No, I meant if the planet itself was mostly made of water. It would then of course not be all that similar to earth. But then, I rather like the weird variety we get with these exoplanets, and I am not that desperate to find earth's twin. I think the media, and sometimes even the scientists, are way too eager to wildly speculate on possible abodes for extraterrestrial life.

    "Actually, only 22 years for the signals to get back, as I'm sure you know."

    ha you are of course completely right. my maths..jesus!

    "If the planet itself was made mostly of water, it wouldn't be similar to earth, but if you mean the % of its surface covered with water, it wouldn't make that much of a difference overall,"

    solaris?
    actually i think life on a water world, though maybe super diferent in some deep ways (ie different circadian rythms, different tides) many forms would be familar. water is water, so jellyfish forms, microlife, fish forms, squid forms, plankton, plankton grazers, snakes, corals, etc seem things that will at one time or another evolve on an ocean planet.
    i mean fishy things have evolved over and over, from hagfish and sharks, al the variety of modern fish, ichteyosaurs, cetaceans, sea snakes, prawns, etc

    i tried to imagine very alien sentient life and couldnt come up with many (obiously hehe)

    maybe
    natural computers of some kind, biological networks or electrical structures or bacteria in ice maybe

    cryolife, with liquid helium for blood or something like the outsiders in known space stories by larry niven

    life in coherent wave forms and turbulance, in some medium like a gas giant, sea, star, space fabric, like the qax in stephen baxters xeelee sequence

    space whales like the spline, also xeelee

    maybe some kind of blackhole or neutron star life?

    post singularity clade civilzations like Angel's in Confluence by Paul McAuley; she had a whole star cluster populated by individuals based on her dna..

    upload cultures like the Festival in Charlie Stross's Accelerando

    can you think of any more that arent variations on the theme of meatbag with hands and eyes that lives in a warmish gravity well?

    "In the unlikely event that you have never seen this, go take a look:"

    maybe.. theyre like the Wederlai...?

    Plus, everyone knows the earth is flat. Why would you sail out in the ocean in search of new land? you'll just fall off the edge.

    Your just pointing out useless information, no one cares if I am an idiot, most people in the world are.
    But we care if idiots open their mouths and poison the air. You can't seriously believe that information not affecting you right now is not important. That is worse than being an idiot.
