What are some theories for creating artificial gravity?

When the space shuttle takes off the astronauts experience

G forces. This is the force due to fast acceleration.

Chemical rockets can only burn 10 minutes or so until

all the fuel is burned up, so the G forces are only temporary.

Once in space a spacecraft is in space it could be powered or accelerated by ion thrust engines. Although their thrust is very weak compared to chemical rockets, they can run 24/7/365.

The energy for them can come from heat generated by a thermopile. You have radioactive material generating heat with hundreds of thermocouples generating electricity from the heat. They've already been doing this, it is nothing new.

However, putting a thermopile on the deep spacecraft being

propelled by ion engines has not been done. Ion thrust is not new either. Even this idea is not new, but nobody has done it yet.

Now if you had enough electricity and enough ion engines

running 24/7 you would be constantly accelerating the spacecraft.. It may be possible to accelerate it 1/2G or 3/4Gs continuously. There is your "artificial" gravity form a

constant acceleration.

No, spinning is NOT the only way!!!

Currently, the only methods known to science to simulate gravity, are with the centrifugal force (rotating section) or constant acceleration. Everything else is just a plot devices for science fiction stories and movies.

Actually gravity is everywhere in space. The weightlessness effect is due to the fact that both the astronaut and the vehicle are falling at the same rate.

When you throw a ball, it doesn't travel in a straight line, but curves toward the ground.this is because the force of gravity deflects the ball from a straight path. When an object is in orbit, the rate of deflection balances the velocity of the object.

On the nasa skylab missions, the astronauts ran on a treadmill while tethered with bungee cords. A certain amount of excercise is the main ingredient to reducing muscle atrophy and bone loss.

today we do have 'artificial gravity' just in Science Fiction.

during the last years there were some people coming up with experiments trying to combine high temperature super-conductors (boh fixed and rotating) and magnetic fields to build a device which could 'limit' the gravitational field of the earth for something in the range of 0.2 to 2 percent.

These experiments were repeated multiple times and failed while trying to repeat them.

furthermore it was determined that errors in the setup caused a false indication of being succesful with it.

In one particular case i remember there was a high school teacher bathing coins in a superconducting magnetic field inside liquid nitrogene or so, having the other end of the experiment on a scale.

This causes the impression of having weakened the gravitational force of the earth by a fixed percentage, cause he used multiple weights and came to the same results.

Later it was figured that the bubbling nitrogene causes a buoyant effect to the probe in exactly the ammount the scale showed on the other side.

so till today .. there's no way to modify or create a gravitational force except bringing masses into some place.

to our misfortune gravitation is the last thing which has not being satisfyingly combined to both quantumn physics AND classic physics. And i think solutions in this field may come if someone fills the last gap in modern science.

here and there you hear stories that specific exotic elements like element 115 or such stuff would have the ability to solve the thing. Fact is: these elements are highly instable and do exist in particle accelerators for a fraction of a second before falling to pieces. So one cannot build anything from it which holds longer than a fraction of a second ... very useful .. bleh

so whatever hoaxters tell ... no gravity modification yet .. period

Gravity is proportionate to mass, and mass is the amount of matter there is, and matter if you think about it is really nothing more than energy.

So, if you can put enough energy in a small amount of space you should be able to create your own gravitational pull toward the point you put the energy at. The only problem is that it requires A LOT of energy. Imagine trying to recreate the gravitational pull of just something like a person that's, let's say, 100Kg. According to Einstein's E=MC^2 that would require 9X10^20 joules (I think it's in joules anyways...) of energy. If you could produce that much energy there wouldn't be an energy crisis...

Put simply, yes, but it requires more energy than we can produce right now.

There are however other solutions. Take a look at Thomas Townsend Brown, John Hutchinson, and zero point energy (may have some connection to gravity...)

If you're interested in the technology, here's a good site for beginners www.americanantigravity.com I prefer their old site though... www.americanantigravity.com/index.shtml

If you're interested in the technology and have any questions, I have been researching this stuff for the past 6 years and can answer almost any questions you have. You can reach me at hinkle_49090@yahoo.com

Hope that answers your question.

Well from what i know you need to have mass and matter in a certain object for it to have gravity. The reason the planets and the moons have such high gravitational pull is becasue is of their great size and astronomicla unit or the distance from the sun and the moon.

So i would think that they would try to make a object or some sort of substance that has a lot of matter and a high astronomical unit. So when i say they i mean NASA.

I truly can't wait for this sort of thing to happen it would be such a big break through for mankind and Nasa

HAPPY SPACE WATHCHING!!!!!

This is tricky, since gravity implies a constant force in one direction, which by Newton's third law would require an constant force in the opposite direction of the same magnitude. However, the solution is relatively easy once we consider that spacecraft are moving vessels and are designed to accelerate. In the future, our spaceships can accelerate constantly at 9.8m/s^2 on the way to their destinations, and then halfway through the trip they can turn around and decelerate at the same rate, thereby arriving at their destination at a controllable velocity and simulating Earth-like gravity throughout the trip.

The funny thing about artificial gravity is that you dont even have to rotate anything or place unobtainium in your ship. If you accelerate toward a direction, then you will have a gravity toward the other direction. This is just like the force you experienced when the elevator you are in is accelerating upward.

In fact you just need to accelerate your ship by 9.8 m/s2 all the time and you will have 1g gravity inside your ship. You will not need anything else, only power source to accelerate your ship.

So you will only need to keep accelerating half the way to your destination, and keep decelerating (which is just accelarating in opposite direction) the other half.

the best we have is a rotation system, once the ship is out of the earths atmosphere, you use thrusters on the hull to send the ship into a spin, thus creating centrifugal forces that will act like gravity.

There is no other way than rotating. There is no electronic machine or other kind of device that could just be turned on to make gravity, even in theory.

Apart from what kniv said, the only possible method would be to put something extremely massive (possibly dark matter) at the centre of your spaceship.

Rotating the ship would be the cheapest and easiest way to create gravity, however.
