Share International holds the view that the method of manifestation
of the crosses of light in glass windows is a mystery known only to Maitreya
Himself and that it cannot be proved one way or another by present-day
science. However, the following attempts by young physics students might
be of interest to our readers.
Since their first appearance in Los Angeles in May 1988, several hundred
more crosses of light have miraculously appeared in peoples homes
all over the world. From America to New Zealand, from the Philippines
to Slovenia, brilliant crosses of light have sometimes appeared in the
frosted glass windows of houses, hospitals and churches, when a one-pointed
light source shines through the glass from the other side.
Witnesses call them miracles and report healings, others travel hundreds
of miles just to enjoy their beauty.
In the extensive media coverage about the mysterious crosses over the
past 10 years, scientists have been asked their opinion about the inexplicable
phenomenon. Occasionally, this resulted in a brief examination of
a window and even briefer comments (which usually refer to the special
structure of the glass, dirt accumulation or atmospheric
influences). Other than that, the crosses of light have never been
thoroughly investigated by the scientific community.
In the last year, however, a more elaborate study has been carried out.
At the Dutch Technical University of Delft, two third-year students, Carolynne
Montijn and Hedwig Rotteveel, from the faculty of Technical Physics, have
spent over 10 months on their cross of light research project.
The subject was presented to them by their physics teacher. He had been
interviewed for a science magazine in connection with modern-day
miracles and had become intrigued by the crosses of light, for which
he had no immediate explanation.
Hedwig: It seemed like a great challenge, especially since we appeared
to be the first to try and explain this phenomenon from within the science
lab. At the same time, that was also our problem: there was hardly any
scientific data to fall back on, so we had to start from scratch. For
our initial research we began by simply calling up libraries and bookstores
to see if there was any literature on the subject."
"It turned out there was a recently published book called Signs of
a new time? by Dutch author Richard Bremer. It describes occurrences of
the crosses of light, crying Madonnas, crop circles and numerous other
miracles taking place around the world. We had no idea all these things
were happening on such a scale, or that any books had been written about
Secondly, we searched the internet, typed in cross of light
and discovered websites from Share International and media reports on
the subject. Also, we found a videotape about the crosses made by American
film editor Frances Robinson. Last, and most important, we had the opportunity
to borrow a small
piece of frosted glass that was cut from a window in Canada some years
back which clearly shows a red cross of light. It was all we had to go
on, but it turned out to be just enough for our purposes."
We read about the theories that the crosses must be signs of some
great spiritual happening in the world, but even if that were so, we thought
the form of the crosses in the glass should still be scientifically explainable.
So we set out to try and prove that.
Our goal, Carolynne continues, was not to establish
the cause of the overnight change in the windows, but to find out exactly
how glass can show such particular patterns at all."
We wrote three different computer programmes which simulate the
refraction pattern (the way in which the light bends when going through
the glass) through a pre-programmed three-dimensional object. We then
measured the surface profile of two pieces of frosted glass: one regular
piece showing the usual pillow-like shape (when light shines through it),
and the Canadian piece with the cross."
"We determined the refractive index of the glass based on the piece
of glass showing the pillow pattern. Using a specific mathematical method,
we calculated a polynomial function which describes the surface profile.
These functions in turn were processed into another simulation programme
using the same theory based on the assumption that the refractive patterns
derive from a simple refractivity (based on Snells laws
"Apart from that, we wrote a third control programme
using measurements without this mathematical method. What we tried to
do was to find out if there was a specific index of refraction which produces
The results were quite amazing, says Hedwig. In their 110-page
report, presented at Delft University in 1998, they conclude that their
computer programme indeed provides a good replica of crosses of light.
Our simulation so much resembles reality that both form and size
of the refractive pattern look identical to the actual cross. In other
words: we have been able to simulate the cross in the smallest detail."
"Our conclusion is that the change from the normal form into the
figure of a cross can be attributed to a change in the refractive index
of the surface of frosted glass to exactly 1.561. So, as soon as light
bends through glass with a refractive index of this exact number, it displays
the form of a cross.
Of course, says Carolynne, for the sudden alteration
of the shape in a window to occur, the surface of the glass somehow must
have changed. As the crosses appear all around the world, it is highly
unlikely that the abrupt transformation of the pattern has to do with
the kind of glass used or the manufacturing process. We had this confirmed
by a local glass company."
"Therefore, although from the point of view of physics we have successfully
demonstrated that when the light bends through frosted glass under a specific
index of refraction, this particular form of a cross is seen, further
research would be necessary into the actual cause of this strange phenomenon.
Perhaps it would have to do with minute changes in the surface of the
glass, caused, for example, by rigorous cleaning; or, theoretically, the
molecular structure of the cross-windows somehow having been altered.
To our minds, for this part of
the puzzle there must be an equally viable scientific explanation."
