    The people who took a chance to make this show with the writers, I can never express my absolute gratitude. This show is absolutely and so quietly blew open the real and hard science fiction shows that we can expect for the next ten years. A living breathing universe. You could create so many spinoffs in this universe but yet it is still a small and personable universe. It is lived in.

    Consciousness is 100% electric, and the 'headset', is Motion, Day-Consciousness. Feeling/Senses is the window to Reality. All experiences is Feeling-Experience, first hand, 'space-time' is Doomed because it gives NO meaning. Motion shape space, Motion become time, and time become Time-Spaces, memoires, periods, in our Consciousness, Memory, Inner Space. Time is the shadow of Motion, , Stuff-side, do Only exist in the Consciousness of Living Beings. Life-side. Sense-organs, Sensing and the Sensed, is All Motion. Every child, knows what time-space is. Rainbow picture our Eternal Over-Consciousness, Colors picture the Under-Consciousness = Day-Consciousness and Night-Consciousness. Day-Consciousness Never sleep, it just goes in Circuits, Day/Night and Larger. Deep-Sleep, is our Night-Bodies, REM is the Coupling-Body.

    Over the past century, the evolution of methods for solving Einstein's field equations, as well as the pursuit of exact solutions, has proven to be a formidable challenge. The task approaches levels of impracticality and extreme time constraints for even the most skilled human mathematicians. Despite humanity's vast creativity and multifaceted nature, we now rely on supercomputers. These machines break down problems into manageable components, run simulations, and reveal insights that may one day be discovered by individuals, all heavily reliant on Numerical Relativity. The study of curvilinear coordinates, Riemannian geometry, and extensive mathematical framework/s, ADW is at the inner workings of Numerical Relativity, originates from the Arnowitt-Deser-Misner (ADM) formalism, named after the creators Richard Arnowitt, Stanley Deser, and Charles W. Misner. The Hamiltonian formulation of general relativity, was first published in 1959, a pivotal role in both canonical quantum gravity and numerical relativity. This formalism provides a structure for comprehending spacetime dynamics by segmenting it into spatial slices, making the equations of general relativity, more conducive to numerical simulation. This is central today, for exploring complex events like black hole collisions, gravitational waves and dark matters..

    Newton only had two laws. *The first is that total force on an object equals the time derivative of its momentum.* - Newton broke this law into two parts: when F = 0 and when F =/= 0. But they are the same thing. If the force on a body is zero, its momentum is constant, so it stays at rest or continues in a straight line. When the force is not zero, this a more correct form because it is still true when relativistic effects are noticed. *The second is the conservation of momentum.* - The law that for every action there is an equal and opposite reaction means that when there is a force, meaning the rate of change of momentum in one direction, there is an equal and opposite force, meaning the change in momentum in the opposite direction. Thus, the total change in momentum is always zero, meaning the total momentum in the universe is constant. It is interesting that Kepler's second law, that a body in orbit sweeps out equal areas in equal times is an expression of the conservation of angular momentum.

    'Black Holes' are gravity-inducing plasmoids. Nature's tendency towards conservation makes the whole concept of it allowing precious matter to be unceremoniously poured into cosmic dumpsters a laughable hypothesis.

    Maxwell's equations were developed by many physicists who have their name on their equations: Gauss, Faraday, Ampere. Maxwell only added the displacement current to Ampere's law. But with this one final piece, Maxwell was able to show that EM fields propagate as a wave at approximately approxmately speed c. But the equations were not clearly stated as there are known today and involved 20 coupled equations, and this was later simplified by Heaviside who summarized the theory in 4 equations. But Maxwell incorrectly set the wave equation equal to zero, which is not valid when sources create light. Heaviside corrected this by setting the wave equation to a source and solving the resultant inhomogeneous partial differential equation. This revealed that the EM fields propagate non linearly in the nearfield and only approximately linearly in the farfield. Recently it was shown that the consequence is that speed of the fields are instantaneous in the nearfield and reduces to the speed of light in the farfield, about 1 wavelength from the source. This has recently been confirmed experimentally by several independent researchers. This corresponds the phase speed, group speed, and information speed. Any theory assuming the speed of light is a constant, such as Special Relativity and General Relativity are wrong, and it has implications to Quantum theories as well. So this fact about the speed of light affects all of Modern Physics. Often it is stated that Relativity has been verified by so many experiments, how can it be wrong. Well no experiment can prove a theory, and can only provide evidence that a theory is correct. But one experiment can absolutely disprove a theory, and the new speed of light experiments proving the speed of light is not a constant is such a proof. So what does it mean? Well a derivation of Relativity using instantaneous nearfield light yields Galilean Relativity. This can easily seen by inserting c=infinity into the Lorentz Transform, yielding the GalileanTransform, where time is the same in all inertial frames. So a moving object observed with instantaneous nearfield light will yield no Relativistic effects, whereas by changing the frequency of the light such that farfield light is used will observe Relativistic effects. But since time and space are real and independent of the frequency of light used to measure its effects, then one must conclude the effects of Relativity are just an optical illusion. Since General Relativity is based on Special Relativity, then it has the same problem. A better theory of Gravity is Gravitoelectromagnetism which assumes gravity can be mathematically described by 4 Maxwell equations, similar to to those of electromagnetic theory. It is well known that General Relativity reduces to Gravitoelectromagnetism for weak fields, which is all that we observe. Using this theory, analysis of an oscillating mass yields a wave equation set equal to a source term. Analysis of this equation shows that the phase speed, group speed, and information speed are instantaneous in the nearfield and reduce to the speed of light in the farfield. This theory then accounts for all the observed gravitational effects including instantaneous nearfield and the speed of light farfield. The main difference is that this theory is a field theory, and not a geometrical theory like General Relativity. Because it is a field theory, Gravity can be then be quantized as the Graviton. Lastly it should be mentioned that this research shows that the Pilot Wave interpretation of Quantum Mechanics can no longer be criticized for requiring instantaneous interaction of the pilot wave, thereby violating Relativity. It should also be noted that nearfield electromagnetic fields can be explained by quantum mechanics using the Pilot Wave interpretation of quantum mechanics and the Heisenberg uncertainty principle (HUP), where Δx and Δp are interpreted as averages, and not the uncertainty in the values as in other interpretations of quantum mechanics. So in HUP: Δx Δp = h, where Δp=mΔv, and m is an effective mass due to momentum, thus HUP becomes: Δx Δv = h/m. In the nearfield where the field is created, Δx=0, therefore Δv=infinity. In the farfield, HUP: Δx Δp = h, where p = h/λ. HUP then becomes: Δx h/λ = h, or Δx=λ. Also in the farfield HUP becomes: λmΔv=h, thus Δv=h/(mλ). Since p=h/λ, then Δv=p/m. Also since p=mc, then Δv=c. So in summary, in the nearfield Δv=infinity, and in the farfield Δv=c, where Δv is the average velocity of the photon according to Pilot Wave theory. Consequently the Pilot wave interpretation should become the preferred interpretation of Quantum Mechanics. It should also be noted that this argument can be applied to all fields, including the graviton. Hence all fields should exhibit instantaneous nearfield and speed c farfield behavior, and this can explain the non-local effects observed in quantum entangled particles. *KZread presentation of above arguments: kzread.info/dash/bejne/pZmExqxwpra3prQ.html *More extensive paper for the above arguments: William D.

    it seems like one should be able to build a photoelectric transistor, perhaps that has been done, perhaps it isn't possible. I like the idea of playing a guitar amp that uses a light based process to cause distortion. Traditional tubes use two sources of voltage across a vacuum. It stands to reason that if you had sufficient control of light you could build a filter to color a signal, maybe in some new interesting way.

    The energy filtering slit location for omega filter is after the fourth sector magnet not between magnets 2 and 3. In effect, the omega-filter produces a 'rainbow' (polychromatic fan of diffraction patterns) where the slit sits. Inserting this then creates an energy filtered image. The power dissipated on the slit edge is less than ten milli-watts. A 300 kV beam and 10 nA gives 3e5 (V) x 1e-8 (A) = 3e-3 (W). So, yes, the slits do warm up a bit, but not by much.
