<![CDATA[Latest posts for the thread "Pretty sweet."]]> http://www.dakkadakka.com/dakkaforum/posts/list/54.page JForum - http://www.jforum.net Pretty sweet. This is a highly technical paper that won't make sense to most people, but what it discusses is so awesome that I doubt it will matter.

We've all seen the invisibility cloak which functions by diverting waves away from the object being concealed. The system proposed in the above paper applies a similar principle to matter. As in (small) physical objects will be unable to strike the object being concealed. Real life Iron Halo? Probably not, but still cool.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224509.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224509.page GMT Pretty sweet. http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224611.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224611.page GMT Re:Pretty sweet. http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224633.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224633.page GMT Re:Pretty sweet.

Its more general than that. An object which 'cloaked' with respect to the matter wave would be non-interactive with respect to matter. Its more like ceasing to exist, than ceasing to be visible.

Slightly more general explanation here.

More on the matter wave here.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224674.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224674.page GMT Re:Pretty sweet.

In that regard, I apologize for my blunt remark. In all seriousness does this mean that they have sucessfully found a way to "destroy" matter? As it is not created nor destroyed.

Also forgive my lack of knoledge in this area, I lean more towards biology.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224682.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224682.page GMT Pretty sweet.

With regard to the destruction of matter: we've known how to do that for some time as the conservation of matter is not the same as the conservation of mass.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224711.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224711.page GMT Pretty sweet.

Ha well once again my school system is proven wrong. Theyre teaching us that in chemistry. I'm sure its just the lazy way of them avoiding questions from students.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224719.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224719.page GMT Pretty sweet. http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224723.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224723.page GMT Re:Pretty sweet.

I didn't read the links but what happens if you fall over while wearing it? The ground's made of matter right? ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224739.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224739.page GMT Pretty sweet. http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224741.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224741.page GMT Pretty sweet.
As proven by Einstein. Light is matter albeit at an extremely high wavelength. Now if light could be channeled around an object you would see a noticable visible distortion and I would not call that invisible.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224814.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224814.page GMT Pretty sweet.

Well, light's not exactly matter in the classical sense. Otherwise it would collapse the universe by going lightspeed and having infinite mass.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224819.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224819.page GMT Pretty sweet.

If the cloak were perfect (ie. functioned across all possible wave-lengths and frequencies), then I imagine you would simply slip through the surface and fall to the Earth's gravitational center. However, the cloak probably won't be perfect, and so is only really useful in terms of manipulating particle beams, and other similar 'objects'.

Yeah. Photons have no (discernible) mass, and so are not matter.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224914.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1224914.page GMT Pretty sweet. http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225469.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225469.page GMT Re:Pretty sweet. I can't see it becoming available for people anytime soon as it will likely cause too many medical problems, or atleast have a fair few bugs (like all new technology) causing it to be unsafe. But once it is the weaponry will have to evolve to counter act it as well. That's how we ended up with guns in the first place, armour became too effective for the old method.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225482.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225482.page GMT Pretty sweet.

But, I'm finding the matter bending one a little more hard to believe than the light bending one. It's probably possible, but it will likely be a very difficult thing to do and have many set backs.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225511.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225511.page GMT Pretty sweet.
If they're standing so that they are on the other side of it then, yes. To everyone on the same side, no. But, that's it in it's prototype phase, it will likely be developed into a cloak.


Actually it's in "rough scientific paper talking about theoretical applications of concentric rings of cold atoms but admitting the presence of a lot of problems with the possible technology" phase. There are no prototypes.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225703.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1225703.page GMT Re:Pretty sweet.

The way I read the article, it bends matter around itself, so rather than simply not interacting with a person, it would act rather like James Bond's magnet watch, bending the bullets, or othe items, around the wearer.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1228102.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1228102.page GMT Pretty sweet. http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1228115.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1228115.page GMT Re:Pretty sweet.

Good point, that is a sort of interaction. That said, a perfect cloak would do that to any matter which was in contact with the person. The only thing keeping us from the gravitational center of the Earth is matter.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1228266.page http://www.dakkadakka.com/dakkaforum/posts/preList/272173/1228266.page GMT
