Perhaps the first reference of Cloaking devices can be found in Ramayana or Vedas itself where Vimanas could disappear at the command of the Lord himself!...Perhaps.But the cloaking device provides interesting technology to explore for the Space ships.


Gravtic Cloaks fro the Space ships:
Gravitic cloaks work by using artificial gravity generators to bend light and other electromagnetic radiation around the ship. This causes the matter of the ship not to register on another ship's sensors. The cloak must be finely tuned to ship's systems to work properly. Additionally, the cloaking device must be carefully adjusted to insure that the gravity waves that it generates in order to cloak the ship are not detected.

As a consequence, the gravitic cloaking device uses a large amount of computer time and power. This means that a cloaked ship may not engage in combat. Shields and weapons system have insufficient power to operate while the ship is cloaked. Additionally, shields produce large scale gravitic disturbances which cannot be hidden by a cloaking device.

The warp coil emissions are the most difficult to hide. Since the warp drives use gravity to bend space around the ship, the faster a ship is moving, the more difficult it becomes to effectively hide the ship.

The cloaking devices in Star Trek's Rum's Empire used almost about the same technologies...

What do you think?
bye!

using weapons while cloaked isn't impossible. just that this aparent cloaking device uses alot of the ships computing power and what not. so you could easily have a cloaked ship that uses weapons(with a better computer).

what is this based on the Star Trek universe?:bugeye:
are we looking to apply this in real life?

Thats what my question is...How can we apply this idea in our own ways...



bye!

I don't think there's much mileage in gravity devices - we haven't even detected a gravity wave yet - and think of the effect of a gravity field, sufficient to bend light tightly, on the occupants.

Has anyone heard of the Philidelphia project? This supposed project used the Unified theory for Gravitation and Electricity to build a huge magnetic generator that was able to make it invisible to radar. They modified the generator after the test was successful and it "supposedly" teleported the ship from Philidelphia to Norfolk and back again. This modification was made because they wanted to make the ship totally invisible.
The reason the test was unsuccessful was because the crew didn't survive. Some were fused in with the ship, some just plain faded from sight.

In theory, it could work in fact it does all the time in space. Black holes are just gravity generators. They suck everything into their singularity. But its like this no one really knows what happens there, they can only SPECULATE.

Let's not confuse stealth technologies with magic.

Let's not confuse stealth technologies with magic.

So your saying that a black hole is magic? It is invisible to the naked eye. Do you know the formula to make light bend?
How much magnetic force is needed to make light bend?

The concept is sound though i wasn't stating that the particular refernence i posted was true.

Shields and weapons system have insufficient power to operate while the ship is cloaked. Additionally, shields produce large scale gravitic disturbances which cannot be hidden by a cloaking device.
Provided a missile has its own power generators and targeting systems, you don't need the ship's systems to use it. Start it up, a small signal to the missile to tell it to launch, and poof! The ship in ST6 was not that big of a deal, espacailly if it launched a modified torpedo that had a booster on it, eliminating the need for the accelerator on board the ship. OF course, you also gotta cloak your tailpipe.

One immediate problem would be that the invisible ship would be totally blind.

And anyway, you could never make it impossible to locate. There would be peripheral effects that would distort light in an obvious way some distance from the ship.

you mean like the effects of the cloaking device on Predator. The faint irregularities in the displacement of the light particles

There is another way to hide a ship, and it may be more possible than the non existant gravity generators.

Use a projection system to show from all angles what is on the opposite side of the ship. If you can project this image solidly enough (holograms?) so that the ship itself cannot be seen through the image, and you can project a full spherical image, the ship is visually hidden.

At least this method doesn't require physics only known in science fiction.

That is being experimented on in a British Lab. Presently they are using Organic LED based on polymer technology where the camoflague can be shaped to euipment outline. It is years away before deployment though.

I think there may be more in tricking another ship into thinking there are three of you, or that you're someplace else, rather than some sort of absolute cloaking device. at least with current tech.

Wasnt a graviton radiation detected in a binary star system named Sirius A and B despite their own life cycle impacta,there was a change in the net gravity...in form of packets...?

Just wondering...

Did I say that? I don't think so.

It is invisible to the naked eye.

So is heat, so is UV - visibility to human eyes isn't necessary for reality.

Do you know the formula to make light bend?

Yes - see http://vishnu.mth.uct.ac.za/omei/gr/chap8/node11.html

None - gravity bends light.

The concept is sound though

What concept? The transportation of a warship, the use of gravitational lensing to cloak it, or a means of making it undetectable to various sensors?

The first two are crap - the last one is sound. Reducing its radar cross section is current technology, making it (almost) invisible to the naked eye is (other than by simple camouflage) is not physically impossible but the technological difficulty is formidable.

No - AFAIK, gravity waves haven't yet been detected. The existence of a graviton (as the quantum of gravity) is also up for grabs.

The concept i was talking about is making the ship invisble.

As for magentic force not being realted to gravity i would like to see a link on that.

1. 'Invisible', 'magnetic' and 'related'. Invisible to what? Radar, human eye, thermal imaging? Even if all three, you can still look for non-EM signatures - sound, magnetic anomaly, gravitational anomaly. In short, it's very difficult to make something completely undetectable.

2. Try:

http://van.hep.uiuc.edu/van/qa/section/Light_and_Sound/Properties_of_Light/20020312194513.htm

Google and the google newsgroups (e.g sci.physics) are good sources if you don't have a library handy.

Oh god when will... i am frustrated...

LIGHT DOESNOT BEND!SPACE AROUND THE LIGHT BENDS...JESUS...

DUE TO WARPING EFFECT.Please refer to Physics forum for a thread related to this.

BYE!

"No - AFAIK, gravity waves haven't yet been detected. The existence of a graviton (as the quantum of gravity) is also up for grabs. "

Ok...Thanks for the link anyways...

The biggest problem with using a "gravity generator"(which doesn't exist) to bend light around an object, is that a gravitator(which does exist) can be used to find cloaked objects. A gravitator is an extremely sensitive sensor to detect the mass of objects, and is frequently used in high tech submarines. Just carry a gravitator around and bingo, super easy location of cloaked objects. Not that cloaking is even possible, heck I doubt we may ever even create gravitation generators. We certainly can't do that today or for the foreseeable future.
