In the realms of science fiction, being able to make things invisible is often taken for granted and is the ultimate fantasy for us mere mortals.
Scientists have been experimenting for years and there is now such a thing as invisible technology. Invisible science is a study that examines whether not the phenomenon known as invisibility can become a reality. Scientists are aware that everything we see concerns the reflection of light. You could say that at night everything is invisible as it is black and light is not able to reflect back from the objects.
Magicians have for several years been able to give the illusion of making various objects invisible by using a variety of tricks. There are various types of invisibility and as such you could see that it is possible to make things invisible. If we stand in front of a solid object we can clearly see it and the prospect of being able to make that invisible is relatively far-fetched. However, invisible technology can make things invisible to radar. Although ships are incredibly large solid objects there are ways to make them invisible from radar. It is not as incredible as it may seem at first glance, because as mentioned previously everything we see is as a result of light being bounced back from it.
Being able to give certain objects the impression of being invisible would be something of tremendous value to the military. This is really what invisible science and invisible technology are trying to investigate. It is purely a matter of physics and examining the way the light can be bent around objects that can give the impression of invisibility. Scientists are currently carrying out experiments using different types of metals at various temperatures to explore this possibility further.
For the time being we will have to content ourselves with knowing that although invisibility is not impossible it is highly unlikely that we as individuals would ever be able to make ourselves invisible to each other. As previously stated the closest we will ever get to this would appear to be by implementing the same methods that David Copperfield uses. Optical illusions can sometimes give the impression of invisibility but again this is just a trick of the light.
Invisible technology and invisible science will continue to strive to find an answer to the question can we make things invisible? However the reality of the situation is that, objects being looked at by humans will not be invisible, but huge objects like ships and tanks may well become invisible to radar.
