Is the Speed of Light a 3Rd Harmonic Wave? International Journal of Theoretical and Mathematical Physics 2019, 9(4): 103-107 DOI: 10.5923/j.ijtmp.20190904.02 Is the Speed of Light a 3rd Harmonic Wave? Greg Poole Industrial Tests, Inc. Rocklin, CA, USA Abstract Schumann Resonant currents are known to exist in the Earth’s cavity. By representing these resonant currents throughout the inner Earth, it is shown through string wave calculations that tension exists between the center of the Earth and the surface of the Earth. Using known facts of the Earth it is possible to calculate Schumann resonance or conversely, insert measured resonance values and calculate tension. The known parameters and the measured values of resonance suggest that there exists wave tension, which acts as an electromechanical connection or “string” between the center of the Earth and all things on the surface of the Earth. It is concluded that naturally occurring Extremely Low Frequency waves penetrate everything living and nonliving on the Earth, thus providing a resonant connection which creates tension, more commonly referred to as gravity (g). Curiously, calculations indicate that the speed of light may be a 3rd harmonic of 1 x 108 m/s. Keywords 3rd Harmonic, Extremely Low Frequency, Gravity, Schumann Resonance, String Wave 1. Introduction recent construction is a direct result of the rediscovery of Historically it has been thought that Schumann resonances research and testing in the field of propagating surface occurs because the space between the surface of the Earth waves, or Zaneck waves, circa. 1936 [4] [5] [6]. and the conductive ionosphere acts as a closed waveguide. Though current research is centered around surface My previous work in modeling the electrical Earth indicated waves, it is my belief that low-level currents flow in and that extremely low frequency (ELF) electrical currents are around all living and nonliving bodies on the surface of the emanating and flowing through the Earth’s core and mantle planet and everything is thus electrically connected through [1]. The currents through, in and around the Earth are all penetrating extremely low frequency currents. Nickola thought to operate at Schumann Resonance.

Tesla’s stated 60 Hz and appear as distinct peaks at around 7.83 Hz goal was to transmit electrical power through the Earth (fundamental). The various even and odd harmonic currents itself, which he viewed as a lossless conductor [7]. are major contributors, and it is thought that the primary Resonant electrical currents are natural to our environment current flow throughout the Earth is a third harmonic. The and thus considered relatively harmless. graph below (Figure 1) shows that the 3rd harmonic, 23.5Hz, has a higher magnitude and thus a dominant signature on the Earth. 2.

These waves give rise to Schumann resonances in the waveguide resonant cavity. These waves are also expected to occur at Venus, produced by strong lightning in the Venus atmosphere and at Mars produced by active dust devils or dust storms, during southern hemisphere summer, when the planet is near periapsis. Within dust storms, dust particles undergo triboelectric charging. The charge transfer leads to charge separation. A lightning discharge is expected to occur when the charge exceeds the breakdown strength of the media present. The transient electric discharge emits electromagnetic waves in the VLF/ELF range of frequency, leading to Schumann Resonance in the surface-ionospheric cavity. In a heterogeneous cavity, Schumann resonance modes are observable using an in-situ instrument. Recently has it been possible to search for these electromagnetic waves from the Mars surface using the UCLA-provided InSight fluxgate magnetometer. The weakness of the vertical component of ULF waves at Mars suggests that the subsurface is electrically conducting, allowing trapping of electromagnetic energy between the sub- surface and the ionosphere.

    Schumann resonance transients and the search for gravitational waves Z.K. Silagadze∗ Budker Institute of Nuclear Physics and Novosibirsk State University, Novosibirsk 630 090, Russia Schumann resonance transients which propagate around the globe can potentially generate a correlated background in widely separated gravitational wave detectors. We show that due to the distribution of lightning hotspots around the globe these transients have characteristic time lags, and this feature can be useful to further suppress such a background, especially in searches of the stochastic gravitational-wave background. A brief review of the corresponding literature on Schumann resonances and lightnings is also given. I. INTRODUCTION The detection of gravitational-wave signals from inspiralling binary black holes by the Advanced Laser Interfer- ometer Gravitational-Wave Observatory (LIGO) [1–3] opens a new era in observational astrophysics and thus is of paramount importance. Recent three-detector (including Virgo) observation of the gravitational wave GW170814 [4], enabling a new class of phenomenological tests of gravity, as well as unprecedented joint gravitational and elec- tromagnetic observation of a neutron star merger [5] are further solid confirmations that this new era indeed has come. As the gravitational-wave detectors are extremely sensitive instruments they are prone to many sources of noise that need to be identified and removed from the data. An impressive amount of efforts were undertaken by the LIGO collaboration to ensure that GW150914 signal was really the first detection of gravitational waves with all transient noise backgrounds being under a good control [6–8]. Correlated magnetic fields from Schumann resonances constitute a well known potential source of correlated noise in gravitational waves detectors [9–13].

  • Schumann Resonances, a Plausible Biophysical Mechanism for the Human Health Effects of Solar/Geomagnetic Activity
    Schumann Resonances, a plausible biophysical mechanism for the human health effects of Solar/Geomagnetic Activity Dr Neil Cherry Associate Professor of Environmental Health 6th September 2002 [email protected] © Dr Neil Cherry 2002-2005 Human Sciences Department P.O. Box 84 Lincoln University Canterbury, New Zealand Schumann Resonances, a plausible biophysical mechanism for the human health effects of Solar/Geomagnetic Activity Neil Cherry Human Sciences Department Lincoln University New Zealand 2/3/2001, updated 6/9/02 Abstract A large number of studies have identified significant physical, biological and health effects associated with changes in Solar and Geomagnetic Activity (S-GMA). Variations in solar activity, geomagnetic activity and ionospheric ion/electron concentrations are all mutually highly correlated and strongly linked by geophysical processes. A key scientific question is, what factor is it in the natural environment that causes the observed biological and physical effects? The effects include altered blood pressure and melatonin, increased cancer, reproductive, cardiac and neurological disease and death. Many occupational studies have found that exposure to ELF fields between 16.7 Hz and 50/60 Hz significantly reduces melatonin. They are also associated with the same and very similar health effects as the S-GMA effects. The cell membrane has an electric field of the order of 105 V/cm. The ELF brain waves, the EEG, operates at about 10-1 V/cm. Fish, birds, animals and people have been shown to respond to ELF signals that produce tissue electric gradients of ULF/ELF oscillating signals at a threshold of 10-7 to 10-8 V/cm.

It has been recognized that the magnetic fields from the Schumann resonances could affect the search for a stochastic gravitational-wave background by LIGO and Virgo. Presented here are the observations of short duration magnetic field transients that are coincident in the magnetometers at the LIGO and Virgo sites. Data from low-noise magnetometers in Poland and Colorado, USA, are also used and show short duration magnetic transients of global extent. We measure at least 2.3 coincident (between Poland and Colorado) magnetic transient events per day where one of the pulses exceeds 200 pT. Given the recently measured values of the magnetic coupling to differential arm motion for Advanced LIGO, there would be a few events per day that arXiv:1612.01102v1 [astro-ph.IM] 4 Dec 2016 would appear simultaneously at the gravitational-wave detector sites and could move the test masses of order 10−18 m.

  • Lightning Detection in Planetary Atmospheres
    Revised version for Weather Lightning detection in planetary atmospheres Karen L. Aplin1 and Georg Fischer2 1. Department of Physics, University of Oxford, Denys Wilkinson Building, Keble Road, Oxford OX1 3RH UK 2. Space Research Institute, Austrian Academy of Sciences, Schmiedlstr. 6, A- 8042 Graz, Austria Abstract Lightning in planetary atmospheres is now a well-established concept. Here we discuss the available detection techniques for, and observations of, planetary lightning by spacecraft, planetary landers and, increasingly, sophisticated terrestrial radio telescopes. Future space missions carrying lightning-related instrumentation are also summarised, specifically the European ExoMars mission and Japanese Akatsuki mission to Venus, which could both yield lightning observations in 2016. Keywords Atmospheric electricity; instrumentation; space science; measurements 1. Introduction Lightning outside Earth’s atmosphere was first detected at Jupiter by the Voyager 1 spacecraft in March 1979 (Smith et al., 1979; Gurnett et al., 1979). Since then, lightning has been detected on several other planets (e.g. Harrison et al, 2008), and it may even exist outside our solar system (e.g. Aplin, 2013; Hodosán et al., 2016). Beyond simple scientific curiosity, there are several reasons to study planetary lightning. The famous Miller and Urey experiment of the 1950s found that electrical discharges generated in conditions mimicking the early Earth’s atmosphere produced amino acids, the starting point for life (e.g. Parker et al, 2011). More recent work has shown that energetic electrons accelerated in the electric fields in Martian dust storms can affect atmospheric chemistry, which may also be relevant for life (Harrison et al., 2016). The possibility of life elsewhere in the universe, and the conditions needed for it, remains one of the biggest scientific questions facing mankind, and provides a major motivation.
