Electromagnetism
is a large, encompassing theory, so its no wonder that many people do not
understand it. A basic book on it will almost immediately dive into calculus.
When it comes to using EMF detectors, may folks have no clue on how to use them
properly or the ability to determine man-made sources (AC) from natural ones
(DC).
The
problem is amplified by the fact that most meters are calibrated at 60HZ AC,
the same frequency as household wiring & other man-made electrical systems.
They are not designed for what we are using them for.
Most
ghost hunters will tell you that ghosts are believed to emit some kind of EMF.
However, when asked why they believe this, many cannot give a good scientific
answer.
Here
is one of our hypothsises explaining how the EMF detector problem can be solved
to some degree.
The scientific method is the best way yet discovered for winnowing the truth
from lies & delusion. The simple version looks something like this:
1.
Observe some aspect of the universe.
2. Invent a theory that is consistent with what you have observed.
3. Use the theory to make predictions.
4. Test those predictions by experiments or further observations.
5. Modify the theory in the light of your results.
6. Go to step 3.
You can think of facts & theories (not just scientific ones, but ordinary
everyday ones) as being on a scale of certainty. Up at the top end we have
facts like "things fall down". Down at the bottom we have "the
Earth is flat". In the middle we have "I will die of heart
disease". Some scientific theories are nearer the top than others, but
none of them ever actually reach it. Skepticism is usually directed at claims
that contradict facts & theories that are very near the top of the scale.
If you want to discuss ideas nearer the middle of the scale (that is, things
about which there is real debate in the scientific community) then you would be
better off asking on the appropriate specialist group
To
begin our quest, we must first take a look at the ghost in the human machine,
the conscious of the mind. Professor McFadden from the School of Biomedical
& Life Sciences at the University of Surrey in the UK believes our
conscious mind could be an electromagnetic field. His theory may solve many
previously intractable problems of consciousness & could have profound
implications for our concepts of mind, spirituality & even life and death.
There
are wide differences in the concepts of consciousness, which are prevalent
among biologists, psychologists, & sociologists. The threefold meaning of
consciousness comes from the Latin word 'con-scio': a) to cut, b) to make a
distinction, & c) to know.
There
are three different ways to know the difference -- 'con-scientia':
1) Through genetic bio-reactive knowledge,
2) Through personal self-reflexive knowledge, &
3) Through social, consensually validated knowledge.
Most
people consider "mind" to be all the conscious things that we are
aware of. However this is not quite accurate. The majority of mental activity
occurs without awareness. Actions such as peddling a bicycle or walking can
become as automatic as breathing. The biggest puzzle in neuroscience is how the
brain activity that we're aware of (consciousness) differs from the brain
activity of all of those unconscious actions.
The
human brain is a symphony of electromagnetic signals, but science has had
trouble finding the conductor of the symphony. One of the problems that
neurologists have with consciousness
(49)
is called the binding problem. The best way to
explain the binding problem is to use the analogy of a tree. A tree seems to
contain thousands of leaves, all of which are contained on several branches.
Neurobiology tells us that the information contained in the mind (all the
leaves) is dissected & scattered among millions of widely separated
neurons. The binding problem is encountered when science tries to explain where
in the brain all those leaves are stuck together to form the conscious
impression of a whole tree. How does our brain bind information to generate
consciousness? The data does not seem to add up & our symphony conductor is
once again missing.
Through his research, Professor McFadden realized that every time a nerve
fires, the electrical activity sends a signal to the brain's electromagnetic
field. However, unlike solitary nerve signals, information that reaches the
brain's electromagnetic field is automatically bound together with all the
other signals in the brain.
The
brain's electromagnetic field does the binding that is characteristic of
consciousness. Conscious information processing is associated with the EM
component of ultra low frequency (ULF) brainwaves in either:
a) dialectically "denser" parts of the brain in the normal awake
state
of consciousness; or
b) a gaseous ionic structure in the vicinity of the mind.
This
is why Paranormal Investigators look at EM fields. It is the basis of life
itself (a great book on the subject that I'd recommend for ghost hunters is
" The electromagnetic origins of life" by Dr. Becker). The brain's EM
field is the only possible thing that could survive bodily death.
So
what happens at death? Using the first law of thermodynamics there are several
possibilities. First, all that energy could transform into heat and bleed out
of the skull. That would also mean no afterlife, much less any possibility for
ghosts. Fortunately, there are other possibilities. The EM field could also
change frequency or polarity. Interestingly enough there is some data out there
that suggests that the mind goes into theta waves just before death, which
gives us a possibility of ghosts.
Using
what data we have from neurology, we can assume that the frequency change could
not exceed much more than 40HZ or so. The bottom line is that we are looking
for low frequency DC EM fields. These types of fields are what we need to take
a serious look at.
The
biggest problem with EMF detectors is that they are not giving you the most
vital piece of information of the EM field, its frequency! They
can only give you the power associated with a field.
There
is an instrument that can give you both power levels and frequency. It's a
laptop computer. Pico Technology has a program that you can purchase that
transforms your laptop into a spectrum analyzer. Using the proper coil or
antenna, so can quickly tell if a field is manmade or not & record the data
from the field onto the hard drive of the laptop.
Using a common lamp as an example, electric fields are present (& measured
in volts) when the lamp is plugged in. When the lamp is plugged in & turned
on, the electrical charge moves, & magnetic fields are created (& measured in milliGauss, or mG). Because
electric fields & magnetic fields have different characteristics, different
measuring instruments & test protocols are necessary in order to assess
emission levels for each field.
