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.

Does anyone know some of the physics behind this or is it too advanced?

Give us a chance. Jiskha has several physics instructors, but they are not online 24/7. Your assumption that this is too advanced is rather arrogant, especially considering that you posted this last question just 11 minutes after your first.

You might want to post this as a physics question.

Hi Ms. Sue,

I am not a frequenter of Jiskha, and not that familiar with how it works. So please bear with me. Having said that, thanks for the input.

The concept of invisibility is indeed fascinating, and while there have been studies and experiments conducted in this area, achieving true invisibility as portrayed in science fiction is still far from reality.

The idea of bending light around an object to render it invisible is based on manipulating the behavior of electromagnetic waves, including visible light. However, it's important to note that current technology is limited in its ability to achieve complete invisibility, especially for complex objects or a human being.

Research in this field has primarily focused on developing materials with specific optical properties, such as metamaterials, which can manipulate the path of light around an object. These materials are designed to have properties not found in nature, allowing scientists to control and redirect light. By carefully designing the structure and composition of these metamaterials, it's possible to bend light around an object, making it appear invisible from certain perspectives.

However, there are significant challenges to overcome. One major obstacle is the range of wavelengths that need to be manipulated to achieve true invisibility, as they span the entire visible spectrum. Additionally, scalability and practical implementation pose significant challenges.

Furthermore, even if we were to develop the technology to render an object invisible, it wouldn't necessarily make a person wearing such a suit completely invisible. Invisibility involves not only bending light but also managing other factors such as sound, heat, and other sensory cues that could give away someone's presence.

So, while there have been developments and experiments in the field of invisibility, achieving true invisibility for complex objects or humans is currently beyond our technological capabilities. However, ongoing research continues to push the boundaries of what is possible, so who knows what the future may hold!
