From Harry Potter (en.wikipedia.org...
) to the Military
) to university departments
), the pursuit of one of the greatest breakthrough technologies is rapidly progressing: Invisibility.
Whilst we are merely at the beginning stages of developing invisibility techniques – the current areas of study being augmented-reality technology,
the other being the use of metamaterials – we can perhaps assume that any alien civilization has developed far more advanced invisibility
With the recent exploration or Mars indications have been building that possible high technology has been seen and photographed by both the Mars
Reconnaissance Orbiter and the two rovers on the surface. We will come to them shortly.
The problem with detecting invisible objects is just that. They are invisible. Never-the-less, tell-tales signs of invisibility, the sort that uses
metamaterials to bend light, can be detected, through extrapolation of light patterns that are otherwise meaningless except when extraneous light
patterns are removed or ignored. An understanding of the scene being viewed, the photographic techniques used, and technology used in processing the
final image aids the drawing-out of the patterns of light that indicate an invisibility tech is at work.
Typical problems encountered in searching for the signs of invisibility include the normal ones associated with image analysis. ATS members have
discussed such issues on many occasions. Here are a couple of threads:
So, what are the tell tale signs of metamaterials at work, bending light? You would think that the light being bent would be invisible. And it is. In
fact a viewer cannot see the light in question.
The tell-tale sign of invisibility is not actually the object in question, rather, it is the effect of the invisibility on other light in the vicinity
of the invisible object.
For example there are two objects, A and B. A is invisible (using metamaterials) and B is visible, partly behind A from your viewing angle. You cannot
see A. You can see B though there is sometimes a slight almost imperceptible line silvery light. This occurs through a process somewhat similar to
“lensing” whereby the bent light of A interferes with the light from B. It is highly dependent upon viewing direction, lighting conditions and
surrounding objects. Viewing an invisible object at at oblique or along a plane of the object has a higher likelihood of seeing the lensing effect.
Here are a couple of links to images that possibly
demonstrate the lensing effect:
In this image, taken by Opportunity's Panoramic Camera on Sol 2679, we are treated to wonderful image of Endeavour Crater. Upon closer examination the
image appears to have strange lines in places. These lines cross stone, cracks and dirt features that should - if the lines were surface features -
break-up them up. The squiggles and lines in question appear to be lensed light caused by metamaterials bending light and interfering with other
In case you cannot see the squiggles and lines in question here is a sample partly annotated image with just a few marked lines highlighted. You will
need to compare the two images:
In this image a number of red lines indicate where suspected lensing lines are visible. There are many other such lines in the image. It is believed
that the invisible structures in the above image come to within several feet of the rover.
(Note that the theorized interfered light sources above do not actually seem to be in contact with the Mars' surface, but rather are between 18
centimeters and 2 meters above the ground. This is hypothesized from climatic and geographic data. However, this is an observation not totally
backed-up by evidence as surface "cloaks" have been surmised as explanations for symmetrical ground obfuscation in some previous rover observations.
We recommend viewing images taken at Victoria Crater.)
In this image further odd squiggles and lines are present. We have noted a few for the viewer:
Can you see these strange lines?
In each image we have indicated only a fraction of the objects of interest. Our theory is that these markings are "lensed light" caused primarily by
non-invisible light entangling with metamaterials that are bending another object's light.
The effect of the metamaterials in polarizing light allows one to detect signs of invisibility that are different to lensing. We call the observed
effect of polarized light "twindling". This occurs when for instance a perfectly ordinary day to day object (such as a pavement) has frost on it. When
viewed from a certain angle in certain light conditions the pavement becomes almost multi-dimensional, displaying various colors and apparent layers
or depth. Of course, under the frost, the pavement is still the same as it always has been: it is usually pretty flat and grey or tar colored. The
effect you witness when the frost effects the reflected light is twindling.
Likewise, light reflected off an invisible surface will rarely betray the twindle effect. This occurs only in very unusual viewing conditions, still
being theorized. Examples on Mars include the following:
In this picture taken by the MRO (it can be found at www.nasa.gov...
) what are
supposed to be sand dunes and surface features are betrayed by the twindling effect of the light. Note the lower sides of the dunes and the chimney at
the vertex of the largest dune. In this small sample picture there are many examples of twindling and lensed light.
The more you look, the more you see.
