Read all about it!

Two papers on the subject, the result of 250 experiments over the course of 3 years, are currently being considered for publication, so this isn't the product of a tinfoil-hat fever dream. The experiment is being described as "the gravitational analogue of Faraday's electromagnetic induction experiment in 1831".

How incredibly cool is this?

Interesting. The article noted the existence of non-theoretical applications, but I wish they's gone into more detail.

Well, if we could create gravitational fields of sufficient strength they'd be a pretty useful form of propulsion in spaceships. And of course, in zero gravity enviromnents we could just create our own. I'm sure that there are all sorts of more subtle uses that haven't occurred to me yet, but those two alone would be huge.

Its nice to see them doing something other then slamming small particles together at high speeds just to see what happens.

Noemon, that's the sort of stuff that occurred to me, but I was curious to know if they thought it was realistic. Like, remember when scientists found a way to "teleport" subatomic particles? I rememeber reading that they did not think this would ever lead to being able to teleport objects or people, but possibly to near-instantaneous information transfer.

Such slamming together of particles is not without its uses by any means.

This development is really cool, though. [Smile]

Yeah Icarus, if the types of things I was talking about are made possible by this technology they'll be a long way down the road, I'm sure. I expect that we'll hear more about this once the papers have been made available for peer review.

Does that mean they'll be able to use it to fly, and to single people out on the basis of their DNA, like the gravitomagnetic fields in Heinlein's The Sixth Column?

I want to see it replicated by others first, but this could be the discovery of the century. [Big Grin]

Geekazoid,

It might actually have 1.0001 tons of possibilities!

very very very cool.

So can they reverse the effect?

Well, duh, obviously all they'd have to do is reverse the polarities. That always works.

erm, you mean can they destroy a gravitomagnetic field? [Confused]

Enigmatic, are you mad? If they reverse the polarity before they've reconfigured the deflector dish, that will mean certain doom!

They should be fine as long as they don't cross the streams.

But crossing the streams is what made the door swing both ways. The future of New York is at stake!

Seriously though, this is really cool.

in all seriousness what CAN this lead to? Like can it lead to artificial gravity?

If they can use this effect to generate gravity waves, does anyone know if the waves will have the same speed as an EM wave?

An interesting Slashdot comment I read: "Artificial gravity is not the real exitement around this experiment. The really important part is, you know, experimental evidence that may provide insight into the unification of relativity and quantum mechanics."

I'm going to abstain from discussion, though, until I know enough to say something worth putting forward.

Lalo -

What, if any, practical purposes does that give us?

Well now. If that result is published, it is definite Stockholm territory.

This thread is a mixed review for me. On the one hand the actual information is very cool (thanks Noemon), but on the other hand I'm irritated at myself and at you bums for getting to all the good Star Trek jokes before I could.

Umm, does this mean we can build space stations and ships with artificial gravity? [Confused]

I guess the first question we need to ask is: How long before we can make this into some sort of weapon?
