      There is no speed of light! What you believe is the speed of light (there are no electrons or photons neither are particles), is how fast it takes to complete the circuit to make the light through the ether (rate of induction)! Light and electricity have about the same rate of induction!

      Nay, i say-!!! Though, tiz true, that through the scientific method, and ever since Mad-Dame Curious sifted soil to refine and distill out that first glowing splodge of radium, it has taken us just over a century for to arrive, perched on the brink of yet again, another E.L.E. or, Extension Level Event. More murderous martyrdom, despotic and fanatical, jeha-die, suicidal like
      ideas are KNOT what is required, here and NOW. Although The Safire Project shows us great promise towards a reversal and remediation pathway, we're still only living in denial, and i fear it's way too late. Like an ox with a ring through its nose, the scientific method, comendered and applied by corporate atomic industries, all and only for the power of a more and better method of eXotic distruction, what has been released and deliberately dispersed everywhere, worldwide, is mega tons of the most leathally toxic compounds ever created, de-liberately, directly into the biosphere, saturating the enviroment, and applying more scientific method to that now, is like watching a dog chasing its tail, spiriling on down into a big black hole of oblivion...

    Questions I asked myself. - In 1820, Oersted discovered by accident that electric current creates a magnetic field. ... Around 1830, Michael Faraday discovered that a magnetic field can generate an electric current if a conductor crosses the lines of force in a magnetic field. This is known as Faraday's law. Light is an electromagnetic wave: this was realized by Maxwell circa 1864, as soon as the equation c = 1/(e0m0)1/2 = 2.998 X 108m/s was discovered, since the speed of light had been accurately measured by then, and its agreement with c was not likely to be a coincidence.

    Já percebi uma coisa , a maioria desses físicos experimentais famosos do passado , conseguiram sua fama medindo alguma constante física , por exemplo Henry Cavendish , Albert Michelson e Robert Andrews Millikan . Aliás , todas essas constantes físicas são muito intrigantes . Por que elas tem um valor aparentemente fixo ? Será que o valor delas realmente é imutável , ou então o valor delas se modifica com o passar do tempo , mas num ritmo extremamente baixo ?

      @Plasma Matter I like Freeman Dyson's statement that classical physics (Newton) and quantum mechanics do not require a grand unifies theory. Each works on it's own. Soothes my simple brain. :)

    • @JivanPal
      @JivanPal 3 роки тому +4

      @@stanleycates1972 , it is not classical mechanics and quantum mechanics that need unifying; classical mechanics emerges from quantum mechanics. What requires unification is quantum mechanics with our understanding of gravity (Einstein's general relativity). The two do not mesh, since one describes the universe discretely, whereas the other describes it continuously. Hence, the search for a quantum theory of gravity.

    Lightwave radiates in medium. The medium drags with the near field but far field. By believing that light medium doesn’t drag with the near field creates a paradox that light exists without a medium.

    What is being observed in that case, is a unit of induction. It's a measure, not a particle, just as time is a concept; a measure, but is not material and can't be physically changed nor can it itself change anything for it doesn't physically exist.
