Artificial gravity field

http://www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html

So, it's a small step, but it's pretty interesting work.
Which got me thinking about artificial gravity fields.

Now, we see them in Sci-Fi a lot..on ships and such, and being used in propulsion systems, but from my (basic) understanding of how gravity works, they are basically making a dent in the fabric of space, to produce the gravity.
Which, ofcourse basically means that they are artificially increasing the mass of the object to a point where the effect is noticable.
Now, in order to achieve 1g, you would need a mass the size of the earth.

A gravity field to achieve 1g in a small area no more then a few hundred meters across will have some...interesting results.
Last i checked, if the earth was crushed down to 15 km radius, and maintained it's mass, it would become a black hole.
Who's to say that when they power up that ship with 1g it wont instantly make a black hole?
Now, if it doesn't make a black hole, who's going to dare to turn it on close to any planet? or on a planet for that matter?
Notice that when the moon comes close to the earth, that we suffer from increased tidal, and seismic activity?
So, turning on a gravity field of 1g on, or close to earth, or any other planet, may be more dangerous then people really think.
It'll be basically the same as moving to planets on top of eachother..

Any thoughts?

Black holes don't exist.

Well, thank you for that, but please keep this thread constructive, it's here for the purpose of discussion.

Everyone go read the Slashdot discussion about this, there's one reasonable post, and the rest are absolutely hilarious.

Just like numbers

its just a rotating electromagnetic field that causes the gravity like effects.

cock

llol wtf? how? how does it produce more gravity than is already made by it's mass?

A decent post on /sci/?  gotta bump this.

What I wonder about this is if this gravioelectromagnetic thinger can have both a positive and a negative like the electrogmagnetic fields.  if this is the case, basically, out earth-> orbit problems are solved.

another interesting thought: 

in the article it said that the effects of the gravolectromagnetic field or whatnot was about 10^18 times more powerful than previously predicted.

in space. things cool down to temperatures low enough for superconductivity all on their own (given no nearby heat source)...

astronomers have been haveing issues explaining how stars on the outside of galaxies orbit at the same speed that stars near the center of a galaxy orbit.  they have explained this with dark matter at the edge of those galaxies.  if hydrogen or helium could display the same characteristics as this exparament when orbiting a galaxy, it seems that it may be possible that this genereated field would fill the gap dark matter is now...just a though.

Hmm, if this was gravity in the conventional sense..emitting a "anti-gravity" might be impossible..
But since it's an electromagnetic field...it may be possible to emit a anti-gravity like effect and push off against a gravity field.
Which brings me to another issue, if you're out in deep space...what will you push off againts? in a solar system the effect might be quite usefull, or on a planet.
But when there's no gravity field nearby...what will you repell?

About the superconductivity in space, it's interesting, i dont know enough about the magnetic properties of superconducters to comment on much, but if this effect can be produced in nature, then the repelling effect i was speaking about earlier might be used on that, ofcourse, this is pure speculation, but still interesting.

This is getting interesting. I guess it really was a good choice to start my apprenticeship to one day be an evil scientist who rules the earth, if no stupid superheros stop me first...

Hmm, this could very well lead to the unification of gravitation and electromagnitism, one step closer to a Unified Field Theory!
