    So when does this launch? Oh wait.... this has nothing to do with Nvidia does it?

    Are they advanced enough to run Crysis?

    So can you travel faster than the speed of light or are you just >600 years old?

    No. Toss a Blentec Total Blender into its atmosphere, and the blender will blend by the time it hits the surface.

    I suppose on their planet AMD is on par with Intel :rockout:

    Another Kepler planet? Nice. The other one was invisible


    I wouldn't like to live where gravity is x2.4 stronger.

    You may just need to get used to it but I admit that would be nothing short of uncomfortable

    i would for a year or two until i get accustomed, then get back to earth and fly when i jump. :D

    You can't just "get used to" it. Without bionics, exoskeletons and other gimmicks it'd be really hard. When the gravity is x2.4 it's a big number. Let's take Jupiter. A helluva big thing.

    So Jupiter is 318 times heavier than Earth while Jovian surface gravity is 2.5 times stronger than Earth's gravity, hence its gravitational acceleration is about 25 m/s2. Same thing would be for Kepler-22b.

    WHAAAAT!!

    There's no mention of mass. Gravity could actually be 5.76 times lower* than that on Earth, if mass was exactly the same, which granted, is not likely. Anyway without knowing the mass there's absolutely no way to tell the gravity.

    * Remember that gravity is proportional to the product of the two masses and inversely proportional to the square of the distance.

    Regarding Jupiter: its mass is 318 times the Earth, but it's radius is ~11 times bigger, that's why its surface gravity is ~2.5 times bigger. 318/11^2 = 2.6 <-- Math is not compltely correct since I rounded up too many numbers, but you get the idea.

    Two points.

    The first is that at relativistic speeds the aging process is slowed, in the frame of the "stationary" Earth perspective. As such, he could have experienced less than a few years of travel, but be >600 years old. Silly relativity.

    The second, the name is qubit. Maybe he entangled two bodies on a quantum level, transferred his conscience, then dissolved the entanglement. Not really travel perse, but definitely long distance fun.

    There is. Gravity bends time and space. By measuring time inside and outside the gravitational field it's possible to calculate it.

    That was an elegant way out of a bad situation. gj :toast:

    Why wouldn't 2.4x the gravity be the same as weighing 2.4x more?

    Aye, it's the same.

    Stronger gravity = bigger weight = faster g

    So if Kepler 22-b's g = Earth's g x 2.4 then human wouldn't feel "comfortable" there. Because all human body / "physics" (blood pressure, organs' positions etc) is designed for our local g. On that planet everything would fall x2.4 faster. Aka that planet has a different "game engine" lol. TBH I dunno do professional astronauts get trained for stronger gravity or only for microgravity.

    Another reason to get Nvidia's Kepler. :cool:

    It's in the habitable zone, yes. It's bigger than Earth, yes.
    But mass is not known, density is not known, so gravity could be more or less than ours.
    It's a 'super-earth' so it could possibly end up being a mini-neptune, not just a rocky planet with some water. Or it could be completely covered with water/ice.
