High-tech cloaking machines could one day render very small objects nearly invisible and perhaps improve military stealth technology, scientists said Monday.
The idea is straight out of science fiction -- cloaking technology made Romulan spaceships disappear in Star Trek. A humble version of the device could become a reality, according to Nader Engheta and Andrea Alu of the University of Pennsylvania.
But don't expect to hide yourself or your spaceship anytime soon, at least not in the standard sense of invisible. In practical terms, the research is more likely to lead to improved technical and research devices, and even these applications are years away.
The proposal involves using plasmons -- tiny electronic excitations on the surfaces of some metals -- to cancel out the visible light or other radiation coming from an object.
Judy, I was going to stump all over your comment, but there are some good points to it. However, invisibility in the spiritual realm, doesn't need a scientific explanation. I think the following verse covers the invisible realms very well:
(AKJV) Colossians 1 16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether [they be] thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
God is "in light unapproachable". I believe that is why we cannot see Him. "Immortal, invisible, God only wise, I light unapproachable, hid from our eyes."
Even the stars become invisible already during the daylight hours.
I have always had a feeling that there is another dimension that we cannot see in the same sense that we cannot see the stars during the day perhaps due to another type of 'light'. the Bible says that God is light and in Him is no darkness at all. Perhaps that is how Romans teaches that the invisible things of God are clearly seen so that they are without excuse. If they are invisible, how can they be clearly seen, unless there is this dimension? If men can sense this other dimension, which other ministers (i.e. Ken Connolly)have also alluded to, that would explain why people refuse real believers in Christ until an emergency, then they rush to REAL believers...in their hearts they know we are speaking the truth...because in theirs hearts they also 'see' the 'invisible things of Him'.
Furthermore, it is shadows that define visible things. If there is NO DARKNESS at all in God, perhaps that is why we cannot see Him.
