Anti-gravity Machine concept

This is a concept I came up with for an idea of an anti-gravity machine.  Let me just state for the record... I do not think this will actually work.  However, while I am quite certain this idea should not work... based upon my limited knowledge of science... it would seem like it could work.  Unfortunately I know I am never going to spend the thousands if not millions of dollars to build this concept to find out.

The basic premise of the idea is the use of angular momentum to overcome the force of gravity.  Imagine if you will, a gyroscope spinning at such a high velocity that its outward force overcomes the downward force of gravity.  Naturally, one of the big obstacles is generating the speeds necessary to create the velocity such that angular momentum is greater than downward force.

What I essentially propose is a spinning ring that is propelled in the same way as a maglev train.  Using Electromagnetic propulsion or EMP to accelerate a ring in a vacuum by the utilization of a flowing electrical current and magnetic fields may in theory generate the speeds necessary for the force to overcome gravity.  Unfortunately, the power to run such a vehicle and the weight to power ratio are significant obstacles.

Two of these rings above one another I theorize can create tremendous propulsion if the angles of the rings were changed.  Using hydrolics to change the angle of alignment of these two rings may create incredible forward momentum.  Once more, such a vehicle would not be limited to operation within Earth's atmosphere unlike jet or other propulsion mechanisms.  In fact, it should operate at peak efficiency in a zero gravitational environment.

This is all theory... and I'd love to know if it is indeed as crazy as it sounds.

I was thinking about Einstein's theory of Relativity the other day and the effect of gravity on time, and I came up with a weird question that I couldn't answer. From what I understand of the theory of relativity, as an object approaches the speed of light, time slows down for that object relative to another object. If you were to take something like a gyroscope, and spin the wheel at the speed of light (assuming that was physically possible) and drop it to earth, would the rate at which it falls change (assuming object falling in a vacuum)? Since Distance=Rate * time, and the time for the rotating object would be different than the planet, would its Rate of descent be that of the Earth's time or that of the object rotating at the speed of light? In other words, would the speed of fall be the same as a non-rotating object?
Your first statement is correct -- in special relativity (SR), the ticking of a moving clock slows down as the velocity of the clock increases. This is as seen by an observer outside the moving clock (i.e., the clock is moving past you, and you'll see the hands turning more slowly than you expect).

When constructing relativity problems, don't think that "the speed of light" is special. In particular, don't construct a problem where some massive object is supposed to move "at the speed of light." That introduces some mathematical problems, and distracts from the real issue. Relativistic effects occur at any velocity -- they are just easier to see for velocities close to c.

You're asking whether a fast rotating object would move differently in general relativity (GR) than a non-rotating object. The answer is no. The fact that it's rotating is irrelevant to it's trajectory. The center of mass of the object will follow the appropriate geodesic, and fall or orbit at the same velocity as if it were not rotating.

However, the gyroscope will precess (its axis of rotation will move around) differently in GR than you would expect in Newtonian gravity.

I know I am years late but help me out here.

How can an object spinning at a relativistic rate Possibly look the same as any other falling object?

I'm not sure what you're asking. Such an object would most certainly not "look" the same, if you are talking about actually viewing it, with your eyes, or camera, or whatever. There will be definite distortions because of the high rotational velocity.

However, for small objects, its _motion_ under a static gravity field won't be affected its rotation. For small objects, the motion is governed by its center of mass, not by the distribution of that mass. This assumes the gravity field is changing (spatial gradient, not time-varying) slowly enough that tidal effects across the object are negligible. If tidal forces are not negligible, then the rotation will have an effect.

Thank you for your comment. I just thought it was an interesting question. I suspect you are right... though I would love to test it to see for myself.
It is an interesting question! If you want to see some of the weird stuff GR does, in particular for the case where the source (large mass, like the Earth, or a star) is rotating, look up "Lense-Thirring Effect."

Assuming it was physically possible, and that the gyroscope molecules could handle the shear force without flying apart! As far as I understand, the energy possessed by the gyroscope spinning at near light speed would be so incredibly high, that its total mass would be dramatically increased. If I am not mistaken, it would form a gravity well. The earth might be drawn to IT rather than it to earth LOL. As to whether it would fall slower, I think yes, Rather the earth and the gyroscope would draw toward each other at an increasingly slowing rate, as according to an observer in some spaceship far away, just watching this.

From the view of a person on earth's surface (standing directly under ground zero of gyroscope impact), I don't know.. I suspect it would seem slow at first and seem to increase speed as you get closer to it (thus get drawn into its gravity well).

Upon hitting the atmosphere it would light ablaze and become a swirling dragon ball Z style fireball, snowballing to huge proportions as it descends.

Upon hitting the surface of earth, it would most likely cause an Extinction Level Event that would usher in a new ice age, and perhaps roaches would ultimately take over the planet.

That is what i thought could happen... I would love to see someone model a simulation of what would happen.

Why so complicated and fast?
Just create a material that allows gravity to "flow around it" without actually being able to affect it.
If you can "shield" the mass completely a simple flatus from the pilot could get it going - if directed properly... ;)

something to note: motion is relative and directional.

So, while this theorhetical object is spinning at the speed of light, that motion isn't oriented in a direction that affects it's decent. ie: it probably falls like anything else.

That said, we don't know. Gravity is a force which we really haven't defined. hence why anti-gravity doesn't properly exist. We don't know enough about it to come up with an inverse for it.

something that might be more interesting, look into Mercury Vortex technology.
