    Depends where you are as well

    I wonder if Dark Matter absorbs all radiation in interstellar space?
    If a man is alone in the woods and there isn't a woke Hollywood around to call him racist, is he still white?

    Actually I don't reckon there'd be any bubbles. CO2 becomes a solid at about -80C IIRC.

    Smile

    The CO2 would violently escape from the solution spraying coke in all directions - why?

    Space has no pressure to hold the gas molecules together. Thats why CO2 doesn't escape from the bottle when the cap is closed. The pressure stops it from escaping from the solution.

    When you open the cap the pressure is lowered and the CO2 escapes. Space has no pressure at all, so the CO2 pretty much fucks off and does what it wants

    Oh and the boiling point of water decreases as pressure decreases, so that would probably vapourise as well, one assumes that said astronaut would not be able to open the bottle at -273 degrees

    That said some ice would probably form for a small period of time as the evaportation would cause the temperature of the water to drop. But the coke explodes either way.

    Best to drink it before you leave the shuttle.

    The CO2 would be dry ice before you got the cap off.

    The reaction you're talking about is because of the ambient pressure that the Coke is bottled at.

    This is assuming that this part of space is cold. Either way that shit is gone once the cap is opened. IMHO.

    are you talking about in a vacuum? or just in a weightless environment?

    in a vacum the bubbles would completely expand and pop out of the coke.

    if just in a weightless environment - the bubbles would stay inside the coke and float around with it, only popping out if the bubbles of liquid coke moved in such a way as to expose the bubbles of air to the edge/surface of the liquid.
    gone.

    Depends if the bottle was opened inside the space ship (in an atmosphere) or outside of the ship (in a vacum).

    My theory is.

    For the latter, no bubbles would occur because all of the the liquid (including the coke) would almost instantly boil away and the gas would distribute itself evenly in space.

    For the former, I think it depends on the pressure inside of the space craft vs that inside the bottle. I think gas always distributes to the area of least pressure, that would be the neck of the bottle. So I suspect that the CO2 bubbles would move towards the neck even if you held the bottle upside down (which is possible because there is no gravity to pull the liquid out of the bottle). Once the gas is outside the bottle, I think it would distribute in the normal manner (btw. I think that the bubbles only exist because the gas is in a more dense liquid (gas is compressed), once it escapes the coke, I suspect it would become gas vapour).

    Another more interesting question - what happens if you open the bottle of coke in a compression chamber when the pressure outside the bottle is higher than the inside ?

    The bottle crinkles or the cap breaks. The gas would not escape the solution.

    Nothing would happen.

    On the other hand.

    Silly man. No, gravity has nothing to do with bubbles in Coke or any other aerated beverage. It's all about pressure. Cue Haldanes Law.

    Well I should change my post, it seems CO2 bubbles are not under pressure (as I thought they were). So the bubbles stay in the coke.

    No. If it did we wouldn't see anything. No photons = no visible stars.

    If you mean the cosmic background radiation, we wouldn't detect it if Dark Matter soaked it up.

    I came across a site where two astrophysicists were conducting experiments to prove that dark matter exists. Just can not find the link now.

    So you drink the coke, burp........what happens??

    ffs bugjuice... look what you've started.

    where opinion holds more weight than fact.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.
