How much longer until Anti-Gravity Engines?

That's a tough one, but nanotech researchers are starting to play around with manipulating the Casimir effect, which until recently was considered unidirectional and therefore useless. What they're doing now is devising tricks by using variations in surface smoothness to create variations in the strength of the Casimir effect, which is important in some nanotech applications but is also a baby step toward something like an antigravity effect, while actually messing around with the type of forces one might expect to come into play in a future antigravity device.

Well, now they've gotten a little further along:

Another trick that could be tried it to pit the law of cancellation of opposing forces against special relativity, using something like a lever with one end moving at near lightspeed and seeing if the other end can still impart an equal and therefore canceling force, since you can make a one-time surge in one direction (such as by swinging a heavy ball around on a chain and letting go), which won't be continous because of canceling force when you try to repeat it.

Truth is we already have antigravity technology, problem is the US government isnt willing to divulge that to the world, to do so would cause a shift in the balance of power in the world, no country would be top dog.
magnetic levitation is not true antigravity
Just as soon as someone comes up with real anti-gravity we'd be happy to use it.
...it's just that pesky real-world physics that's holding us back...

I would essentially agree.
Well if the current government is still keeping tech like Anti-gravity under raps its for, an honorable reason,and not out of spite ,because balancing world politics with emerging tech would be the path to take if we as a planet were to unite together as one people.
To answer Brent it would be maybe the 2020's or 2030's just about the time we go to Mars,we'll going to need a way transport equipment on Mars.

Wasn't there an article just a while back that talked about how, in addition to mass, spin can warp space producing interesting gravetic effects? The article was published earlier this year, but for the life of me, I can't seem to find it anymore.
You mean the Podkletnov gravitational-shielding effect? Here's something about it:
Podkletnov gravitational-shielding effect
And a Wikipedia article:
http://en.wikipedia.org/wiki/Gravity_shielding
The common notion of a gravity shield may be misleading, since it assumes that gravity is a pulling force. I like to think of gravity as a pushing force (by virtual particles), where the Earth partially shields us from particles coming from the opposite side of the Earth, in effect allowing us to be pushed toward the Earth, since the same forces coming from the opposite direction are greatly diminished by the presence of the Earth. In the classic demonstration of the Casimir effect, this happens in two directions, where two highly polished metal plates stick together, presumably because pushing forces betweeen the two plates are limited to those of short wavelength while those outside run rampant, holding the two plates together. But that's a strong hint as to what has to be manipulated in order to ever devise anything like what the OP is calling anitgravity engines. And some small degree of such manipulation is being worked on now as part of nanotech research.
A way I can see anti-gravity is if you have negative mass material.
Effect of gravity is minuscule in the microscopic level so there is no worry about particles coming loose.
Elctro-magnatism rules the microscopic realm.
Your body may be held to the earth by gravity, but your body is not held together by gravity. Otherwise, astronauts would find space travel pretty fucking painful. The cohesive forces at that scale, as the poster above me said, are quite different. The only way your body would 'break apart' and lose cohesion is if the electronics of the molecules within it were neutralised - basically, chemistry boils down to attraction between opposing charges, and if we could neutralise that, we could 'vaporise' someoen just like a romulan disruptor.
Incidentally, someone did come up with an idea a while ago of creating something similar (the idea was to use it to vaporise waste and other undesirable things, like communists). The idea was to create an interference wave in phase with the main sigma bonding molecular orbitals of the substance you want to vaporise, and thus totally disrupt the chemical bonds. Didn't work, perhaps thankfully.
