    Nice piece on Tesla's longitudinal waves.

    Tesla's mistake was not really so big. Especially not a big mistake when compared to those contemporary scientists who were absolutely certain that the Earth *didn't* have any resonant frequencies, who *knew* that radio waves would not travel around the curve of the Earth, and who dismissed Tesla's wireless transmission system as crackpottery; as an unworkable violation of known physics. When "Schumann" VLF earth-resonance was rediscovered in the 1950s, nobody in the conventional sciences dared court the embarassment of admitting that Tesla had been right all along.

    Tesla is mostly a hero among the non-scientist "underground," while in conventional circles he is still ridiculed for trying to distribute electric power without using wires, or rather, by sending it through the ground. Everyone (still) knows that this is impossible, even in theory.

    Yeah, right.

    Tesla was a true genius and not kind of genius, everyone says to even above average intelligence.

    Tesla has made lot of theories based upon his work that were ridiculed but were proven many years after his death and till this date lot of his theories become accepted and even expanded beyond.

    Electromangetism is really fascinating and there are lot of fields where it can be used, since we live on a big mangetic field that not only gives possibility for life by withstanding solar radiation, but it also influences the shape and form, organisms of polyc ellular basis and how they are forming. Like a test with trouts from the same fish in two different fish tanks, with identical oxygen in water, temperature and food. The only difference was one fish tank was surrounded by a mangetic field that was simulating the earth's magnetic fields power based on what scientists believe it was in jurrasic times. The fishes in the artificial magnetic field grew different, with more muscles, the sceletton was more robust which gave the trouts a more "neanderthalian" look, they also had some more resillient attributes to changes of their environment unlike the normal trouts that died off quicker by changing water temperatures. So the earth's EM field not only affects electric circuits but also organisms, since we all are nothing else but EM fields ourselfs, it also affects the brain.

    Here would be a nice topic to speak about quantum physics relativity nuclear reactors all kind of accelerators energy that could be produced trought them and all latest high level physics.

    If you read through this article you will realize that there is a big "IF" out here.

    IF they can find the Dark Matter in the first place. Only dark matter has negative energy density to make Warp speed possible (according to them). Sounds like a sales pitch to fund their project.

    US scientists announce discovery of Einstein’s gravitational waves

    Gravitational waves, which are ripples in space and time, were first detected at the US-based Laser Interferometer

    WASHINGTON, February 11. /TASS/. US scientists on Thursday announced the discovery of gravitational waves predicted by Albert Einstein in his theory of general relativity a century ago.

    Gravitational waves, which are ripples in space and time, were first detected at the US-based Laser Interferometer Gravitational-Wave Observatory (LIGO) in September 2015.

    Prominent English scientist Stephen Hawking hailed the landmark discovery expected to revolutionize astronomy.

    "It is a result that is at least as important as the discovery of the Higgs Boson," Hawking commented on his Facebook account. "With LIGO's increased sensitivity, we can expect many more detections, all improving our knowledge about how the universe works," Hawking added.

    Valery Mitrofanov, a physics professor at Moscow State University, said a team of Russian scientists joined the LIGO project back in 1992.

    "We will fully realize the importance of this discovery later, as it was with the electromagnetic waves," he said.

    I would wait a few decades before swallowing this news. The problem is that a lot of this GR-related physics (cosmology, astrophysics) engages in
    circular logic. They use theory to interpret observations which are supposed to test the theory. This essentially nullifies the whole point of doing
    experiments.

    The LIGO experiment is supposed to detect 10^(-18) m distortions of the array spaced every 4 km (https://en.wikipedia.org/wiki/LIGO). The problem
    is that the Earth is not an elastically static entity. It is continuously distorting with increments much higher than what is to be measured. And there
    is no way to subtract this tectonic noise since there is no model for it, i.e. one does not know what it is to be able to isolate another signal on top of it.

    In actual operation, noise sources can cause movement in the optics which produces similar effects to real gravitational wave signals;
    a great deal of the art and complexity in the instrument is in finding ways to reduce these spurious motions of the mirrors.

    I guess we just have to trust their "art". What would be more credible is they could get continuous data and via time-domain Fourier analysis
    identify signals that are inconsistent with the spectrum of tectonic noise. But it seems they have to wait for "events". This detail is actually
    another problem for this experiment. They can't build up enough samples to do robust statistics. So their "art" is really art and thus not all
    that solid.

    Here is a press release on the Russian contribution to the LIGO experiment:

    http://www.eurekalert.org/pub_releases/2016-02/lmsu-lit021116.php

    I would say it is a rather impressive contribution.

    Oh my! The above is a true revolution in science. Basically, quantum mechanics can be interpreted in different ways
    and we live under the Copenhagen dogma. But pilot wave pseudo-determinism has been slowly gaining ground. One
    can actually get all the main quantization effects in a classical fluid system including the self-interference in the double
    slit experiment, discrete orbitals, etc. Now we have a device that cannot be explained within the existing dogma and
    directly supports the wave-guide paradigm.

    now there is negative mass . As well as quantum electrons existing in two places at once . And observers being able to alter path of electrons . There is dark energy . There is dark matter . Cosmology is totally confused . Physics too . I feel sorry for them . They need research grants . All they get sometimes is chalk board .

    The world is not as we see it . It is infinitely more mysterious . My experience of reality has changed . As I grew older . Such events as premonitions in dreams . Remote viewing . Advance knowledge of events . Convinced me that mental reality is far bigger than physical reality . Existing within it's own domain . A sea of souls . Yet science has no answer . But philosophy does . And it can guide them .

    Quantum theory is as weird as it gets. Until resolving its issues I dont believe we will be able to say Copenhagen theory is correct or not as well as any other.

    We can not say that any one is more correct than the other until proven but than we will know Very Happy

    But physicist are stuck and it seems that only building much more powerful accelerators is the way to solve the problem.

    The existing Quantum Mechanics (QM) is an incomplete theory. The all-important observer who supposedly collapses the wave function
    during an observation is not even part of the theory but some ad hoc add on. This is simply BS and the Compenhagen voodoo masters
    can go and get stuffed with their nonsense. One of the key elements of QM claimed by the voodoo masters is that there are no hidden
    variables underlying QM effects. Supposedly this was proven by Neumann but actually wasn't as shown by Bell and others. I remember
    being taught this voodoo as God's Truth (TM) at my university. They were leading me around by the nose.

    It just so happens that Schroedinger's equation can actually be derived based on the simple assumption that space and time are not
    continuous but discrete (i.e. quantum foam). Schroedinger pulled the equation from his a**. I would say this terminates the Cophenhagen
    dogma but we will have to wait for decades for this reality to become main stream.

    Google a very informative book with the following keywords: emergent quantum mechanics pena
