Does anyone believe that one day, a device will allow us to defy gravity?
At the moment, we need lots of power to fly - to break the earths gravitational pull. Do you think that one day in the near future, someone will invent a "gravity shield" making flying possible with virtually no energy transfer?
Answers:
there is a thing already that does defy gravity-the cost of living-which proves that everything that goes up does not necessarily come down-you don't have to be able to create differential equations to realise that fact-after you've thought that one out,prove that if
x = A cos mt +B sin mt
D^2 (x) + m^2 (x) =0 for all values of the constants A,B and m
note D^2 is the second differential
i believe its possible
if we believe in the law of physics then no.
absolutely man!! we've been to the moon in a rocket!
Most likely yes. It will be that one person who is only born once a few millennial that can change mankind. But antigravity will ahve to find a way to use gravity to undo itself to be any good.
Yes.although anyone who does invent such a device will risk being whacked by a combination of Boeing & BP.
eventually it will become possible.not in our lifetime though..
A-haaaaaaaaaa, yep!
think so yeah. Gotta figure out that darn graviton and how it works though.
I cannot see it as gravity is the pull of the earths rotational cycle is it not?
But that does not mean to say that it will not be done. If one could work out why by spinning something the energy is pulled towards the centre then perhaps you could find a way to oppose that in a controlled way ( or it might shoot you into space or wherever)
yes, but not for a long time. it would have to exactly match the deformation in spacetime caused by the mass of the object trying to negate the effects of gravity.
I think they've made something already, albeit on a small scale. They experimented with a frog and I saw a picture of it in suspension in some sort of chamber.
Don't fly high. Come down. Impossible dreams
I believe it could be possible with the development of new science but this would somehow be able to manipulate the current understanding of gravity.
I don't think I'll live to see it in my lifetime but the prospect looks good for it to develop.
It's already in existance and has been demonstrated and it works.
i belive sooner or later this device will be created.
You can't 'break' or 'defy' gravity.
You can apply enough upward force to exceed the downward force caused by gravity (i.e. weight).
Since we do not know why or how gravity arises (only that it does) it seems unlikely that we can devise an 'anti-gravity' machine, even though it has been popular in science-fiction for years.
Note, in the film '2001' the centrifical force due to the space station's rotation was used to give the impression of gravity but this is NOT 'artificial gravity'.
It would be nice to think so, but this might be one of those occasions in which it is easy to imagine but impossible to actually do.
It's pretty well accepted in physics that perpetual motion machines can't be built, as they would violate the established laws of physics. You don't get anything for nothing.
However an "anti-gravity machine" would allow you to raise a mass with little or no energy and then harness more potential energy than was put in by dropping the mass off the side of the "anti-gravity machine".
And as there's no such thing as a free lunch in this universe at least, I think we'll be out of luck!
Not a shield as such - but it may be possible to either create particles that have a negative gravity that could be used like the air in the air tanks in a submarine.
Alternately it may be possible to wrap an object in its own universe and so cut off the effects of gravity entirely.
