. I am pretty sure that the Sodium-Hydroxide processed Raney Nickel- the stuff
. that is good to go, is pretty safe, especially since it is packed in a liquid . that limits oxidation and must actually be dried out to use. . Actually, they treat a very fine powder. Of course for LPD, I do need a solid . block. Scott, I am pretty sure that in solid form the sodium hydroxide is what makes it pyrophoric by Leaching Al pores into the surface areas and leaving Nickel plated cavities it becomes immediately dangerous- The powder is a little more complicated because fine metal powders form Casimir geometry between particles due to dissimilar packing geometries even without activation. Rayney Nickel powder combines both methods and must be stored as a slurry after activation. I could see them shipping the solid alloy and letting us leach it out ourselves or possibly larger powders that are not pyrophoric but anything else would have to be restricted due to safety concerns. . I use the term Event Horizon to simply define a dividing line between process-time . inside the cavity versus outside of it. Apparently someone else besides you and . I are talking about this stuff since in my original exposure to this idea--that . individual used the term Event-Horizon, comparing the altered Space time inside . the cavity to the gravitationally accelerated Space time inside a . Black hole---except in this we are on the opposite side of the border since our . events appear to happen slower to the folks living inside the cavity. Scott, I used event horizon to describe the maximum of "equivalent" acceleration, any large mass will actually produce Equivalent acceleration but time dilation accumulates so slowly you need an event horizon or dead star to make comparisons on the same scale with dilation due to luminal velocities. In both cases we are talking relative rates of change between space and time but in one case time is constant relative to change in spatial position while in the other time rate changes relative to a stationary spatial position. I have read that equations not involving C should not be called relativistic such as the Casimir formula but the dynamic Casimir force does involve C so I think my terminology is on solid ground since it is "change" in Casimir force that develops catalytic action. This said the event horizon was used to demonstrate equivalent acceleration and the point was that at the mesoscopic scale the Casimir plates are to a hydrogen atoms what an event horizon is to a spaceship -in fact it would also slow down hydrogen caught in the "pressure" zone or outside the plate material (think billowed sail) just like the astronaut -it is only in the tiny segregated area we call the cavity that it accelerates time. . I am quite taken with your interpretation that the oscillation along the time-line might . mean it is traveling forwards then backwards in time. Maybe . . . but here is . the problem: The relativistic astronaut has been traveling more slowly along . his time line---less time has elapsed for him, nonetheless, when he emerges from . his Spaceship Back on Earth he emerges into his brother's point in history. I am not certain if matter can actually leave the "present" or just does a 4D transformation where one spatial dimension trades places with time such that a different inertial frame simply means the "present" is wider or thinner than our frame. This gets into a weakness I have always had regarding velocity and acceleration where some people insist you need "acceleration" to produce time dilation while my take is that you only need a luminal difference in velocity to accumulate dilation. -maybe someone will chip in and explain it to me- . Likewise, when the catalyzed reactants emerge from the cavity, they are not . emerging from our future---if they are then you and I have got to send . ourselves the lottery numbers from fifteen minutes in the future---how about . it??? (I actually tried a similar thing with the Electron Einstein-Bose . Condensate inside a superconductor disk, positing that the condensate locked in . the electron zombie state over time as well as over physical distance---no . results yet!!!) See articles about Professor Ron Mallet http://www.physorg.com/news63371210.html who intends just that using powerful circulating laser beams. He hopes to receive messages from the future when they turn on their prototype. I have written him without reply and have considered exactly the scenario you describe but even looping a transmission while inside the other inertial frame or between frames still undergoes a translation every transmission between frames. Though experiment: Say you had a macro scale Casimir cavity sitting in front of you on a table. The cavity is a pyramid shaped metal enclosure with an open bottom turned on its side so the open bottom is facing you. When you place an object inside the pyramid it appears to shrink, the further back toward the point of the pyramid the more the object appears to shrink -in fact you may find yourself pushing the object your entire arm length deep into the cavity even if the outside of the cavity is less than an arm length in dimension because your arms is also translating between dimensions. If you close your eyes and reach for the ball in the actual spatial position nature will do all the transformations for you and you will "feel" the ball exactly where you put it and be unaware of any Lorentzian effects in scale but the nerve signals may be upshifted like the effects on plasma spectra.
