My Theory on space travel?

Question

(Feel free to discredit me, you HAVE to, i understand) Ok if we can finally create 'anti-gravity', we could create a sheild of anti gravity, this would allow us to leave earths atmosphere without the need of rockets, then once in space we can use ion engines. Ok im 16 please dont insult me, just tell me what u think, i heard about ion engines and how they could be used once in space off a site.

Answer 1

I am insulting you.


You are talking rubbish.

Answer 2

Interesting theory - Ion engines are here, now - however, the anti-gravity thing is a little sci-fi.

Just imagine if we had anti-gravity technology - forget about space travel for a moment - the world would have all the energy it needed, just turn the anti-gravity on a large mass tied to a generator, and when it acquired a great enough height and lots of potential energy, turn of the anti-gravity and let it fall back to earth, spinning the generator and producing electricity all the way down.

Think about how much planes and public transportation in general would be revolutionized with anti-gravity technology.

And a good night's sleep - can't get much more comfortable than when no forces are acting on your body and you're literally sleeping on air.

I bet you can think of other uses for anti-gravity right here on earth - ex: building construction and brick laying would be a heck of a lot easier, for one. The elevators would be gone.....no more huge pumps to get water up to the 50th floor.....etc...etc....

Back to reality - first, we have to determine just what gravity is, why it is, and then, maybe, we can find out if it can be negated.
Believe it or not, Einstein had gravity tied to time and energy levels and how an object always seeks the lowest energy levels in the slowest time zones .... maybe he was on to something........

Answer 3

The flaw is in the idea about anti-gravity. We already have ion engines. We don't even know what gravity is yet. We call it a weak force and that is about it. Anti gravity would null the force of gravity but it would not lift you only lower the amount of force necessary to get you into space.

Answer 4

Nice theory but the only fault is the 'if' factor.
Gravity is created by the earths rotation at surface level it creates a force of 'X' ( I think it is about 15lb per sq inch but it has been a long time since I looked at this sort of stuff) The nearer the centre of the earth you get the greater the pressure, the further away the less pressure. I cannot see away around that but that is not to say there is not one, just that man has not been able to work it out yet.. Keep thiking outside of the box and it may be you taht discovers it.

Answer 5

The Euro space agency just sent a robot to the moon with Ion engines. Hit the moon just a few weeks ago. Done that part.

It's the anti-gravity that seems like a few centuries in the future.

Answer 6

Albert Einstein, once said "all the knowledge in the universe is nothing without imagination",(he said something like that.)
Let us look at it in two ways,

A) You might actually discover something and change the world with your ideas.
B) If an idea does not work it will make great fiction, write a book and inspire someone/people who will make your idea work.

A friend of mine suggested using the atmosphere to push a craft into a void generated by ion engines, he is still working on his idea, he promises to pick me up and take me for a flight when he finishes his project. (that was ten years ago)

Hope you do invent it, because you can take me on a flight (don't forget the people who support your ideas :)

Answer 7

It is a perfectly good theory but in practice I think Einstein would say that an anti gravity device is impossible because gravity is the consequence of the geometrical arrangement of the universe and to build a device that would be capable of reversing the effects of gravity is far fetched.

The device would have to generate extremely high energy, almost approaching an infinate amount, in order to stand the remotest chance of disturbing the normal laws that govern gravity

Answer 8

How do you propose to power this anti-gravity shield?
According to the laws of thermodynamics, the anti-gravity shield would take AT LEAST, if not more, energy to lift the space ship up and off Earth than it would using just about any other means of propulsion.

By lifting the space ship up off Earth's surface the spaceship gains gravitational potential energy. If an equal or greater amount of energy is not spent in the process of doing this than the this whole thing amounts to perpetual motion and is thus forbidden by the laws of physics.

Answer 9

ION engines do exist and do work. They continue to increase velocity, but it takes while to get them going. Great for very long distance though with little fuel. Some laugh at anti-gravity, but if the graviton does exist, then there may in fact be an anti particle that could in theory at least be harnessed. Of course, the graviton may not even exist.

Answer 10

The only problem is that anti-gravity isn't even on the drawing board. We can get to space easily enough and ion engines seem to work fine. But remember, it will still take YEARS to get anywhere interesting, if not hundreds of years.

Answer 11

H.G. Wells wrote a book called "The first man in the moon" published in 1900 that used anti gravity panels to lift a spherical spacecraft.
He didn't use ion engins, he just pushed from the earth and then pulled to the moon finally using the panels again to land.

206 years later and we still haven't found the anti-graviton.......still looking though.
