    One for Lutz.

    If I stood on a set of scales in a spacesuit (ie a closed environment), and didn't eat anything for a month, would I weigh the same? I'm pretty sure I'd be thinner, but would there therefore be a corresponding amount of (I assume) moisture in the suit to counterbalance the weight loss.

    Following on from this, could I not therefore drink this moisture to avoid dehydration? In effect - I would die from heat loss?

    Well you would probably die of starvation first :p and run out of energy to keep standing

    Yeah, you'd be dead in week. So the question is, would your fetid stinking corpse weigh the same after a month?

    Wouldn't some (most) of the mass be converted into heat and then radiated out through the suit?

    If you can read this you really need to fiddle with your forum settings.

    As you began to starve your body would start to consume itself (first fat, them muscles) to provide energy for your vital organs - which would then be lost to you in the form of heat. So yeah, you would weigh less.

    Also, what are you doing about oxygen. I'm guessing you'd have to run out of air at some point.

    Space suit would not radiate any heat.

    And dying wouldn't really affect the point I'm making.

    @LeoliansBro

    Magic spacesuit, eh?

    In that case you'd die from heatstroke, since your body would have no way of cooling itself.

    So the question you're really asking is "does matter converted into heat" weigh the same?

    I don't care whether you survive, I care how much you weigh at the end.

    Of course, it has to be the same amount.

    Just be sure to do it away from your treadmill.

    The blast from jet engines straining to reach take-off speed against the 7mph force of the treadmill could throw your results off.

    Assuming that the spacesuit is a perfectly closed system, from which nothing can escape, it stands to reason that yes - you'd weigh the same.

    So no energy can leave or enter the spacesuit. Therefore mass inside the suit will stay the same but it might change form i.e. live human to dead human.

    Well glad we sorted that one out nice and quickly. Maybe I should lock this before Lutz sees it...

    Even better: If I attach a powerful magnet on the front of my car, then suspend another magnet in front of it (think carrot on a stick), will I move and get free energy?

    No. The magnet on the car is pulling the suspended magnet backwards with the same force the suspended magnet is pulling the car forwards.

    Give yourself 5 or gig, you're worth it.

    If I put down two coins of the same value on a table and ask you to choose one, after which I remove the one you chose and put down a third, again identical, coin next to the one you didn't choose and ask you to choose between the two (new and old) - which coin will you pick?

    Funnily enough most people will pick the new coin, since the very act of *not* chosing the "old" coin subconsciously reduces the perceived value of it. Fanboyism at the micro level, really.

    There are 3 doors. 1 has a prize behind. You pick one. Then 1 of the other doors is opened to show that a prize is NOT behind it.

    You then know the prize is either behind your door, or the other unopened one.

    You are then offered the chance to switch doors? What should you do?

    switch, and that's a stupid annoying question.

    I've turned off all the avatars and crap, so don't expect me to be impressed by yours.

    Always switch. It's because the person who chooses which door to open after you made your choice has more information than you.
