Can A Satellite Read Your Thoughts? – Physics Revealed

Note (20th Feb 2011): The figures presented in this article have been revised. The current version can be found here. (or in the bottom of this page)

Most people, when they hear of Synthetic Telepathy, especially by means of satellite, jump to the immediate conclusion that such things are not possible. If they were, we would have heard of them, right?

Looking back at the history of classified technology, places and events shows a wide range of time periods where things are kept secret. Stealth aircraft are just one example, the F-117 Nighthawk was not publicly acknowledged until 1988 although it had been in operation for over six years. Documents sealed for “National Security” purposes can be hidden away for up to 70 years. So, it would be really surprising if certain technologies were not classified as you read this.

Whilst you can hide certain technology to an extent, what becomes very difficult to hide as time passes is the physics of a given technology. An example would be a nuclear device. Whilst you could, in theory, hide a given nation’s development of a nuclear bomb, the physics still shows that nuclear fission/fusion is possible. Thus, if you weigh up the various factors that are required to create a nuclear device, you can make an educated guess as to the likelihood a nation has such technology.

With this in mind, I decided to look at the transceiver and the physics involved in that process. Its all well and good claiming that a satellite can read thoughts, but how does the physics stack

Does The Brain Transmit Like A Radio

To understand this, we first need to look at how antennas work, its relationship to neurons and what similarities, if any, exist. Coming from a QED angle, if you take a look at figure 1 we can get a better viewpoint of how a moving charge creates an EM wave. As the electrical field moves towards the bottom of the picture, virtual photons are radiating magnetic energy into free space. As per Maxwell’s equations, a changing magnetic field will induce a changing electrical field resulting in a free standing EM wave. This is a good applet that shows how a moving charge produces electromagnetic radiation.

So, what is the connection with neurons? Information is processed by the brain in the form of electro-chemical interactions. That is, every perception you have sends electrical signals to the brain that are routed to specific areas that deal with them. The neuron has a long strand called an axon, along this axon propagates an electrical charge. With a resting potential of -70mV an action potential moves along the axon, in a millisecond, elevating it to a voltage of +30mV which drops off over a few milliseconds. This makes an action potential a form of alternating current with an almost triangular waveform. As such, this produces a very weak form of modulated electromagnetic radiation or radio source.

For the astute reader, it means that a neuron is a type of transducer.

Can You Hear Me Now?

So, whenever you have a thought, feeling, speak or our heart beats, tiny little radio emissions are being made by the brain that emanate into free space. The real questions are, given modern technology can these signals be detected and does a method exist of associating them with particular functions? That is, whilst signals in this power range may be detectable, is there something unique about the signals that can be used to differentiate between different roles?

Let’s deal with first problem, detection. I tracked down an example of satellite sensitvity to radio frequencies that should act as a baseline. The following data is from NASA’s Jet Propulsion Lab:The sensitivity of our deep-space tracking antennas located around the world is truly amazing. The antennas must capture Voyager information from a signal so weak that the power striking the antenna is only 10 exponent -16 watts (1 part in 10 quadrillion). A modern-day electronic digital watch operates at a power level 20 billion times greater than this feeble level.

So, does the brain emit radio waves at a power level greater than 0.0000000000000001 Watts after several hundred miles?

To answer this we must turn to this scientific paper. From this paper, we can observe the charge per square centimeter which is around 22-29 microamperes. We can perform some rough math on these figures that will reveal the answer to our question. The equations are rough and leave out a lot of additional factors, that said, the final figures will not be far from the truth and will probably under-estimate the capabilities of current classified technology.

So, using the formula Watts = Voltage x Amperage, we get the following peak power:

0.003 V x 0.0000029 A = 0.0000000087 Watts/cm2

So, at source, the weak radio emission of a cubic centimeter of brain matter is well within the detectable limits of the satellite. We now need to project that into space and determine the signal strength at orbital distances. To do this, we need to apply the inverse square law to the emission and the formula is provided in figure 2. So, the formula would be (disregarding gain):

(0.000087 Watts/m2) / (4PI x (500000m^2)) =

0.000087 / 3141592653589.7932384626433832795 =

2.7692960097989788423785774826817e-17 Watts/m2

This is fine, its somewhat larger than our baseline, but nothing that cannot be accounted for. Firstly, we need to identify the frequency range. As noted before, due to Maxwell’s equations the motion of the action potential results in a changing electrical field. In turn, this results in a changing magnetic field and thus a free space radio wave.

Typical frequencies for an action potential are in the range of 0-500Hz which will result in free space waves in this range, known as the SLF and ELF Band. This somewhat matches up with experimental evidence that shows humans do broadcast signals on the ELF band. This scientific paper and others show that SLF/ELF reception gear and antennas are of a practical form factor to be placed upon a satellite. An array of such satellites (see figure 3) would use the principle of aperture synthesis to create a type of space-born Very Large Array.

Given that the Ohio State’s radio telescope had a sensitivity, in 1977, of 2 ×10^-22 W m-2 per channel and the VLA is described as being 100 times as sensitive, any signals we are producing could be heard loud-and-clear by a space-borne array. This arrangement would provide for a very high resolution of brain activity.

What’s more, the development time line for this technology places the capability to detect brainwaves as far back as the early 1970’s. Given an average lifespan for a satellite as 5 years, with an initial deployment during 1970, the satellite technology would be in its 8th generation today.

So, we can detect the signals but now it must be processed.

Information Overload

There is a significant difference between detecting a signal, or signal range, and being able to process that information and make sense of it. To do this, we need to find unique patterns in a signal that would allow us to isolate individuals and isolate neural activity we can categorize.

The three main characteristics of a wave are its amplitude, frequency and phase. To be able to detect a single person, in a crowd for example, we need to find something unique about the waves the are emanating. This allows us to eliminate the noise and only have information regarding a single person. There are a number of ways this can be achieved. In a satellite array, examining the timing of signals received across the array, on a given frequency range, will provide you with both the location (in 3D) and the coding of the neuron structure. From this, the function of the cluster can be inferred by comparison with generalizable signals in a database.

A cluster of neurons will broadcast across a given range of frequencies, slightly out of phase and with slight variation in amplitude. The characteristics are dictated to by the rate of neuronal firing, the timing of neuronal firing and the amount of energy in the neuron at the time. Given that neurons are biological and the unique structure of a cluster, the statistical likelihood of the wave characteristics being identical between different people would be quite low. Thus, from a technical viewpoint, pattern analysis lies at the heart of the development of a lexicon.

Now, we have our signals, we know what they mean, all that’s left is to scale the process up, allowing us to track thousands of targets in real-time. The only real limit here is processing horse power and satellites.

Conclusion

In answer to our original question, it is technically possible for a satellite to detect your thoughts, your emotions and your perceptions and pass that information to a computer for interpretation. I bet that comes as quite a shock.

The only ever real restriction was the receiver sensitivity in the SLF/ELF band. The whole tinfoil hat brigade will be pleased, but will ultimately feel stupid as waves in the SLF/ELF band cannot be blocked by tinfoil hats. Even in the deepest tube stations, you would be heard perfectly from orbital distances.

Do you see the benefit to intelligence gathering?

So, given that it is technically possible, the questions now become which governments are using it and why was the public not informed?

There will be a lot of raised eyebrows in the world tonight.

Update 2012

Bright ideas…literally.

 
I received an email in regards to some of my calculations in this series. Apparently, discussions around the web have found several errors and even provided some better examples. Whilst the articles are meant for the lay person, I thought it best to update the figures in light of this new information.

I will resist the urge to go back and correct the articles, after all, this is supposed to be an ongoing investigation. The scientific method requires that theories are revisited when the underlying facts change and I feel that the following figures are a better representation of a single neuron. I will endeavor to be as precise as I can be and point out where I have made assumptions or idealisms.

Reception And Detection

So, thanks to the guys over at ATS (AboveTopSecret.com), we have the following to work with.

If a physical or chemical stimulus is strong enough to cause depolarization from the resting potential of ö70 mV to around ö50 mV, the voltage-dependant Na+ transmembrane channels open. Favored by both the concentration gradient (see Table 1) and the electric gradient, Na+ ions flow into the cell, creating an electric current (I = ΔQ/Δt). The influx of Na+ causes a local reversal of electric polarity of the membrane, changing the electric potential to about +40 mV (a swing of 110 mV from the resting potential. The small cross-sectional area (A) of an axon and high resistivity (ρ) of the axoplasm yield an extremely high resistance (R = ρL/A).Ê A piece of nerve axon 1 cm in length (L) has an electrical resistance of about 2.5 x 108 Ω (comparable to that of wood). The produced electrical current:

I = V/R = (110 x 10-3 V)/(2.5 x 108 Ω) = 4.4 x 10-10 A

http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/Casey_Adamson/Personal%20Web%20Page.htm

Firstly, we need to determine the power supplied to the axon and we do this with the following equation:

0.05 * 0.00000000044 A = 0.0000000000022 Watts ( 2.2 x 10-12 W)

Next, we will use an idealized calculation to determine the power density of the signal at 500Km and drive both the dBm and dBW of the signal. I say idealized as not all of that power in the original current is converted to a radio wave. Not only this, but we are assuming an isotropic radiator, that is, the energy propagates uniformly in all directions.

With a little understanding of Antenna Theory, we can observe why this not a problem:

1. ANY piece of conducting material will work as an antenna on any frequency.

Even a straightened paper clip will work on 160 Meters. All we have to do is properly match the the transmitter to the the paper clip, and the paper clip will radiate ALL of the power fed to it! The aperture of this antenna will have a radius of 5/32 wavelength (.079 sq. wavelengths cross section area); essentially this is close to the theoretical “Isotropic” source. If this antenna is located in “free space”, the radiation will be almost equal in all directions.

http://k9erg.tripod.com/theory.htm

Thus, these figures are generalizations, but are not far from the actual values.

0.0000000000022 Watts / (4PI x (500000m^2))

0.0000000000022 Watts / 3141592653589.7932384626433832795

= 7.0028174960433947738308855883906e-24 W

= -201.54727191871927618387329422323 dBm

= -231.54727191871927618387329422323 dBW

So there we have it. To detect a single neuron firing at 500Km, we require a sensitivity of at least -231.55 dBW at our receiver. But the story does not end here.

Within the brain, entire clusters resonate at specific frequencies. That is, there could be hundreds or thousands of axons all emitting, slightly out of phase, so these signals could be above the threshold that I have outlined above. I feel that this method explains the detection of ELF RF energy detected coming from humans. That is, its a product of photons received versus time.

Transmission

Buried in the comments section of one of my previous articles was a series of three very important scientific articles. The articles are as follows:

  • Chaos control and synchronization of two neurons exposed to ELF external electric field (view here).
  • Unidirectional synchronization of Hodgkin–Huxley neurons exposed to ELF electric field (view here).
  • Fire patterns of modified HH neuron under external sinusoidal ELF stimulus (view here).

These scientific articles demonstrate the basic mechanism of controlling the firing pattern of a neuron remotely. That is, they show how to interface with the brain remotely and induce a controlled hallucination.

This is the basic mechanism by which the Artificial Intelligence can send information directly to the human brain. Using the E-field of an ELF radio wave, neurons can be stimulated into firing under the direct control of the external field. By stimulating patterns consistant with correct neural coding schemes, voice, pictures, video and sensations can be communicated to a target.

At this point, I see no reason why any function the brain is capable of performing cannot be controlled by this external field. The only real difficulty is identifying the correct neural coding schemes for specific actions or responses. This includes complex thought processes and decision making. Knowing exactly how far the NSA has progressed in this matter is impossible to gauge at this point.

So, Can A Satellite Read Your Thoughts?

If it were just a case of sheer distance, then yes, it would not be a problem. Many have suggested that a parabolic dish of enormous size would be required, but this is not the case. To some degree the atmosphere itself will act as a dish, but the photon wavelengths are so huge that focusing them on to a detector is not really required if using a closely spaced array. Further, there is the issue of ionospheric reflection, but this is imperfect and does not have great impact on the E-field.

I will not rule out a ground-based system, or some form of hybrid. No doubt during early testing such ground-based systems were employed.

All said, a satellite system is a question of engineering, not of physics and it can do a lot more than just read your thoughts.

One Response to “Can A Satellite Read Your Thoughts? – Physics Revealed”

  1. Thoughts The Realm of Reality?

    Shape and forms of things seem to be adaptive to the world which surrounds or affects a particular body. Certainly, this is true in a sense but not necessarily. Objects are conditioned by the physics of awareness, the higher law in which all lower laws must obey. A sphere of emptiness envelopes all binary relations by way of negation, limitation, or undefined schema- as all things that come to be already exist as an empty set of ideas.

    This immaterialist position called idealism, a claim that all objects are actually ideas, makes good sense especially when operating on multidimensional planes that are made up of those very ideas. Of course, any rational idealist would border the absurd to think think it possible to crash head on into a concrete wall without suffering the effects of a Rock Hard Concrete Idea!

    It is equally absurd to think that there exists something other than the mind. Where would this substance come from?
