Let's invent a force field

[SagaLore]

First we need to decide what kind of field we want.

You can create a field in the presence of air, by locking the air in place.

Or you can create a field that is basically intense EM, by repulsing matter.

If you want to get really complex, you could create a field that blocks both matter and energy, using some kind of exotic matter, like dark matter. You'd need to control it somehow though.

I would prefer a completely energy based field. Perhaps on the premise of Star Trek's holodeck - you control photons.

Discuss.

I want a gravity field but we don't know what gravity is.

Right, so that isn't something we can pursue.

Does anyone know - can you bend the path of EM radiation (from source A) in the presence of an EM field (from source B)?

 

[Geniere]

Sure its easy. Just position a few blackholes to guide the beam anywhere you want. You can also expand and contract space to alter the EM frequency.

We aren't even close to creating our own singularities yet.

I'm trying to focus on this as a practical application... what can we do now? I know that supercooling certain superconducting ceramics causing an EM repulsion (magnetic objects floats above ceramic plate).

Very low EM frequences have trouble penetrating matter. If we could generate a very high output of a dense low em, and then influence it to bend around an object - could that repulse matter?

I'm sure it can probably be done. I am in no way highly technical but when you mentioned something out of star trek, I remember a few years ago there being an article somewhere called "Beam me up" or something. Anyways, they managed to actually "beam" one atom across a room or something(at least, I think it was an atom, could've been just some kind of energy or something...I dunno). Either way, hope this discussion goes well...

(If anyone knows what I'm talking about please point me to the article...it was awhile ago but I bet some geeks out there know exactly what I'm talking about)

no

And there is no practical way to repulse matter using an EM-field (the amount of momentum transfered by a photon is extremely small, that is why solar sails need to be huge). Type I superconductors are perfect diamagnets which is why a magnet can float above them on its own field. It has nothing to do with bending light or repulsing matter.

They didn't actually beam any matter. What they were doing was using some kind of process to "synchronize" two particles, so when you made a change to one particle, the change was reflected by another particle. It was a way of transferring information, but nothing applicable to transferring mass.

No, it 's not.
You can not use quantum entanglement to transfer information. You CAN however use it for e.g quantum crypthography so there are applications.

 

[DrPizza]

I believe they *have* created a singularity already. (or at least the evidence points to it)
And, in another year or so, they expect to possibly see evidence for "black holes" created a few times a month.

 

[DrPizza]

Oh, and my suggestion:

How about a massive magnetic field?
I believe there's a (fairly) well known experiment where a frog was levitated. You may not be able to repel knives (in fact, you'd attract anything magnetic), but you'd be able to repel people, since they're mostly water.

Bonus: research shows that the brain starts hallucinating/malfunctioning in super strong magnetic fields.

 

[poorchap]

If one uses the principles of spin correlation, then we wouldn't need a field. We would be happy to know there are/is alternate universe(s) perfectly correlated with ours that have these fields already in existence.

If you are able to recognize a change of state in a particle - all you need is two states - then you have a binary system. Binary equates to digital information.

 

[Crescent13]

I'm not all too highly technical, but I was wondering, can't we take electricity from point A to point B without wires? With electricity going between two points, anything that goes between the two points would be electrocuted. example


A-------------------B
A-------------------B
etc...

Electricity have some of the same properties as magnetism right, what if we put two like poles across from each other, like this

+==========+
+==========+
+==========+
etc

This would create a magnetic force feild that would stop all metal objects from coming through, right? Or am I just too sleepy to think tonight. meh, i'll post anyway.

EDIT: Don't you think we should expand on this idea for humans and other things?

 

[Robotoer]

For repulsion of matter, would that work? because an atom is neutrally charged. the outside has a negative shell created by the electron, but the protons in the middle are positively charged. As for bending EM radiation, a really powerful magnet could bend the EM radiation. Also, if this is possible, isn't it possible to "trap" light? If you get a powerful enough magnet, can't you shine a beam of light at it so that the light begins to orbit the magnet? If you were able to do that, then you could create an optical battery or a light bomb(hehehe). Anyways, what would happen if you could create a shell of electrons around an object? like if you could use magnets to control the electron, then wouldn't it be theoretically possible to make electrons orbit an object instead of a neucleus. If this happened, would matter bounce off the electron shell just like how it does for atoms, but on a smaller scale?

Yes, but you can not use this system to transfer ÍNFORMATION faster than light (FTL). The problem is that in order to "use" this system you also need to send along some "classical" information (e.g the type of polarizer used) , and that information must be sent using a conventional channel. Hence, this system is complettely useless for transfering information (well, I guess you could still use it, but why?).
That said, the principle can still be used for quantum crypthography but then information is still transfered slower than c.

Nice link, but how is that a reply to my post?

Because there are already articles explaining how to transfer data.

 

[f95toli]

No, there are not. You are missing the point.
As I wrote above, you can NOT quantum entanglement to transfer information faster than light because you ALSO need a CLASSICAL channel of information (e.g a phone line). Without the extra information from the classical channel there is no way to interpret the data from the "quantum channel".
In quantum crypthograhy that is not a problem because you do not need to transfer any secret information via the classical channel.

I want a tactical magical force field that can deflect the horror of the worlds stupidity ;( sorry i had to say that ! i know what are thinking "what an total retard" but hey ... i don't care. I am crazy person with no idea what you guys are talking about but seriously what is gravity really is>?? Also how the hell we are going to repulse matter using an EM-field ?


LOL another useless post by me !! /me thinks about how he can identify /deflect stupid matter.

The implications of entanglement are even more intriguing. By manipulating one entangled qubit, it is theoretically possible to change the value of its pair instantaneously, across any distance. This could potentially lead to faster than light communication and data transfer, overcoming a reverse salient in our current space exploration technology.

This report states you can, but, I found a lot more articles that explain you can't, but do talk about uses in cryptography like you're saying. So for now I'll just say I don't know either way - and let's get back to this force field stuff.

To venture back on topic....

I had a chem prof in college who used to work for 3M. He once told us about a situation in a 3M plant that involved large amounts of static electricity which somehow formed an "invisible wall", which would physically prevent people from walking across the room.

Here's a link.

AWESOME DUDE LETS TRY DOING WHAT EVER they DID AND FIND OUT THE SECERET and then we could make a device and sell it millions to army : ) we would be making crap loads and also getting our name printed in history books

Well I could see how this is possible if it were very humid. Think about it, water conducts electricity and if it were humid enough, to the point where the water molecules are bouncing off each other much more often than not, the static electricity would expand throughout all the area that was humid.

There a problem arises, the static electricity would exand everywhere, what to do? Because the article states that his electric meter thingy was maxed out a good distance away, that shows what is happening in the surrounding area. What you would need to create the wall is to have the 2 lines (PP) that are producing the static charge be close enough that they can transfer all their electrons (electricity). This next thought is a theory: down on the atomic level, the water molecules directly in the middle of the 2 static sources would create a barrier of molecules, electrons holding the water molecules together because we of course EM force is the strongest force we know of (many orders of magnitude over gravity). Ill draw some of my thoughts and post after class.
