    if you stay in space for a long time then your bones will get crushed because they are usally used to gravity pulling them down, but in space they weaken therfore if you came back down onto earth your bones would get crushed.................................................................................but what if you drank lots and lots of milk

    I'm guessing I'd get belly-ache.

    If the bone structure doesn't think it needs any calcium, then it rejects the calcium. And in microgravity bone strength is not important.

    So what you should do is to tell the bone structure that it need the calcium, you do this by exercise. If the bonestructure thinks it needs the calcium, then it builds up itself with the available calcium.

    But I'm not sure it is that simple. It seems that the bone structure is not so easily tricked. You'll still lose bone strength of some reason.

    Btw, if you don't like milk, then you can take calcium pills. Next time you are planning to go up in the space, ask your farmacist for advice.

    Maybe we could all chip together and send you there.

    well that is very thoughtful but no thanks. i feel safer with 2 feet on the ground. but i would like to feel what it is like with zero gravity
    maybe i can just become a puppet

    So sign up for a trip on the Vomit Comet, lot cheaper than going into space, you get to feel zero gravity for 30 second stretches of time, maybe ten times like that. The latest traveler to do that: Steven Hawking. He was happy as a lark, able to feel free for the first time in a long time, free of the bounds of gravity which holds him chained to a wheelchair.

    You need resistance for the minerals to deposit on to the bones I think.

    Actually the problem can be solved by having a centrifugal wheel providing artificial gravity for space travelers, either in space hotels or 6 month sojourns to Mars or ten year trips to Pluto. I imagine for the really long trips you would HAVE to have something like that if you wanted to actually go back into a gravity well, moon or planetary.
