Invisibility. I've been reading all over the place about this, but mostly sensational. Some, however, state that the Government has been working on a sort of "invisibility cloat" for military, air force and marine tactics. But get this, it works on the basis that "light can be bent" ....
Insane hey!?! What are some of your professional thoughts about this? I am VERY interested to hear? And what would it take to say render myself completely invisible? --
Ok, I heard that the current technology isn't that advanced. That they can only render a cylindrical type object invisible.
BTW - The cloak works like this, if one can bend light around an object the objects is rendered invisible.
Thank you for using the Jiskha Homework Help Forum. :) Did you ever see the movie "The Invisible Man?" It would be fun to be invisible but it's scary to think of someone else "snooping" around!

Something like that might be possible as the fields of nanotechnology and optoelectronics progress. We already have analogous systems that (1) greatly reduce microwave (radar) cross sections airplanes by using absorbing materials and multfacted shaped that suppress reflections, and (2) suppress background noises with sound-cancellation headphones. What would have to be done is use wavelength-sized arrays of optical intensity and phase sensors on the backside of the object that one wishes to hide, and use them to generate a wavefront on the other side that would match the wavefront that would be there if there were no object. There is no fundamental physical reason this cannot be done, as technology advances. It would probably be limited to rigid objects, such as a cylinder.
I meant to write "multifaceted shapes" in the second sentence.
The B2 bomber would be an example, for radar invisibility.
Awesome you guys.
Hey SraJMcGin,
Haha, yes. It certainly does raise some questions! D:
The concept of invisibility is indeed fascinating and has captured the imagination of people for a long time. While there have been advancements in certain areas of stealth technology, it is important to differentiate between the scientific principles and the practical applications.
The idea of bending light around an object to make it invisible is based on the concept of manipulating light waves. However, achieving complete invisibility, like in science fiction, is currently beyond our technological capabilities. This is because light interacts with objects in a complex way, and bending it perfectly around an object is a challenging task.
Researchers have made progress in creating cloaking devices in certain limited scenarios. For example, some experimental cloaking devices can effectively hide objects from certain angles or wavelengths of light. However, these devices often have limitations, such as working only for specific frequencies or being restricted to certain shapes or angles.
To render yourself completely invisible would require an advanced and sophisticated technology that is currently not available. It would involve developing a method to control and manipulate light waves in real-time, adapting to the changing environment and the observer's viewpoint. This is an incredibly complex endeavor that involves multiple scientific disciplines, including optics, materials science, and advanced computational algorithms.
While the government may be involved in research related to stealth technology for military applications, it is important to note that the information available to the general public is often limited and could be speculative or exaggerated.
In summary, the concept of invisibility is intriguing, but achieving complete invisibility is highly challenging with the current level of technology. Ongoing research may lead to advancements in certain aspects of cloaking technology, but it is unlikely to result in the kind of invisibility seen in movies or books in the near future.
