    Just another insight into the scary cotton candy machine.


    Great news, though! Now we need to start looking for distant tranmissions of "I Love Z'gglrp".

    and only 41 light years away.
    Bummer to get there and discover they were wrong

    ER, wouldn't the gravity on those things be ridiculously high?

    On gas giants or large planets? Not really, since the radius increases too, putting you further from the body. I think >0 to 3G is common on most planets. 'Gassy' planets have lower density too, so their radius can be pretty large compared to dense planets like earth.

    Edit:
    http://curriculum.calstatela.edu/cou...1/gravity.html

    and

    The gravity on these things would be something along the lines of 1.1-1.2 G if they're like Neptune.

    and

    Hal Clement wrote a book called Heavy Planet where he had a gas giant spinning so fast that the centrifugal force countered gravity, but only at the equator. At the poles you were really heavy.

    Yes, you're 0.5% heavier at the poles it seems.

    Yes, but the cold will make you burn fat more easily, so it all evens out. Right?

    Exciting stuff!!! I'm a big sci-fi nut so this is really really cool. Now we just need some "earth type" planet to be discovered and faster then light travel.

    travel faster than light is SCI-FI
    The best we could do is 0,8 parsec (1 parsec=300 000 km/s=speed of light)
    but what's great about space travel is that the travel is less long for the traveller than for the spectator on Earth. So it would take less than 41 one years for the traveller (I lost my book of notes to calculate it).

    I had a course on history of science, was amazing. The only thing I was addicted to is questions related to sci-fi, my teacher wanted to kill me with question like " How much time to go on the nearest solar system ? how do you calculate it ? what's antimatter ? Is it the same as the matter in thoses big black holes ?" I didn't understand everything, but it was fun !

    In this entire universe, there HAS to be "intelegent' life somewhere, we may not find it in our lifetimes, but this is definately a start. (As of yet, I haven't found too much intelegent life on earth, hehehe)

    Well it's only going to take us 41 light years to get there....and 10 to utterly screw it up.

    ???

    Okay Han Solo, a parsec is a measurement of distance, not speed. One parsec is 3.25 lightyears. A lightyear is how long it takes light to travel in one year, therefore it is both a measurement of speed and distance. Put another way: It's 5.88 trillion miles.

    I think what you were trying to say is that in theory we can never actually attain the speed of light - the best we'd be able to do is about .99 the speed of light. It starts to get all mathmatical at that point and I don't recall my Einstienian theory too well, but in short, it'd get messy. The whole time going backward thing or something. pld:

    Anyway, back into my cave

    we would need infinite energy to get anything to the speed of light which would be heavier then light itself, so that's why it is impossible >.>

    The relativity thing that Einstein talks about refers to the experience of time by the traveler. Time remains constant for the FTL traveller, but since he's accelerating away from the point of origin, time seems to accelerate when compared to way time is experienced at the point of origin.

    VERY POOR EXAMPLE: If you travel for one minute at the speed of light, something like six months (six weeks?) passes for everyone at the point of origin, or something like that. My head hurts trying to recall my physics classes, as they occurred over 20 years ago.

    FTL is indeed science fiction, until we actually try it in practice. Remember:

    "In theory, there is no difference between theory and practice. But in practice there is." - Jan L.A. Van De Snepscheut

    Yeah I know about FTL, just dreaming! Maybe wormholes or something might be invented?

    I'm just a sci-fi nerd XD.

    I was going to say!

    More specifically, 1 parsec is the distance you have to be away from a point for a distance of 1 AU to cover 1 arc second.

    It's disturbing that star wars would make reference to such a unit at all, considering it is defined in terms of Earth's orbit around the sun.

    Anyhow, extrasolar planets are hours of fun, especially ones in habitable bands. Too bad that the vast majority of extrasolar planets so far discovered are supermassive jovians, or worse, probable cthonians.

    Lol cthonian in the sense of a jovian that has had it's atmosphere blown off by proximity to the star. Or else just a really hot jupiter. I was doing some fascinating reading on models of hot jovians where alkali metals like sodium vapourise and then ionise in the atmosphere, turning it yellow

    Though Planets Found in Potentially Habitable Setup would be kinda neat.

    Scientists tune in to the radio signals and hear chanting, aww yeah
