    Would it be possible to do this?

    No. If it has mass, then there is nothing you can do about it.

    Depends on what he means. Mass and weight are two different things. Something has mass as long as it is made of matter. Weight is the force of attraction by two masses. Example: baseball and earth. They attact each other.

    The answer is still no. If what is in it is massless, then it will weigh nothing. If what is in it is not massless, then it will have weight. However, as mass cannot be eliminated from massful objects or introduced into massless objects, then "making" it weigh nothing is not possible.

    I disagree. I think there could be a type of mass that weighs nothing, maybe even less than nothing. Physics and Maths are similar in a way, and I believe just like you can go to the negative stages in numbers, you can go to the negative stages in mass.

    How is it possible to weigh less than nothing ?? That is almost like saying there is the speed of light, and the reverse speed of light.


    Besides, what about antimatter ? I though that would destroy any matter

    Nothing is energyless(zero energy= doesn't exist ). GR says anything with energy is effected by gravity. Therefor something that is weightless(isn't effected by gravity) doesn't exist.

    Thats like saying gravity can go into minus figures ie it will repel.....A totally speculative notion that has no evidence in reality.

    Well if there WAS something that the earth repelled, we probably wouldn't find it on earth. :P

    Edit: Never mind, I mistook the point made.

    Really, i would say if you go small enough you will always find zero energy somewhere?? or would the smallest particles/energy of all be all bound together with no space between?
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..
