The Quantum Vacuum itself exerts radiation pressure all of the time on everything. As measured within the accelerated time-frame, photon collisions of a given intensity are happening at exactly the same rate as the corresponding photons that manifest outside of the cavity, as measured from that external time frame; however, when we stand outside of the cavity, we see these equally energetic collisions as happening at a faster rate, inside the cavity and we conclude that more outward directed momentum is being imparted, inside the cavity than outside the cavity. The observer inside the cavity would see the same difference in forces, except he thinks the outside world is passing through time more slowly; therefore, he concludes that his side of the cavity walls are receiving momentum at a normal rate, but that the corresponding photons are striking the external walls more slowly. In other words, both observers agree that there is more outward directed pressure inside the cavity than there is inward directed pressure acting on the exterior of the cavity. Again, the pressure is the same inside and outside the cavity in each of those time frames, but they both see the same resulting difference in pressure from their own perspective.
Really, the question hinges on whether the inside surface of the wall is in a different time zone than the outside surface . I think, if our theory is true, that the surfaces inside the cavity must be inside the faster time zone since it is this very surface that is causing the time-rate shift. Otherwise, the space would still be too small for the longer waves! What is causing the Casimir Effect if what I am saying is not true?

What we describe as time dilation from our perspective outside a cavity is perceived as spatial motion from the local perspective of the remote object inside the cavity such that the as plates move closer together from our external perspective they have an opposing motion from an internal perspective that starts to add distance at the inverse of distance^4 – It is a very real motion to the vac wavelengths [virtual particles] allowing them to fit in a space that appears too small from our perspective outside the cavity. You may be able to create imbalances inside the cavity but I remain convinced the overall “pressure” remains balanced externally and internally and you need to involve a 3rd body such as gas atoms that have a natural affinity for one region over the other in order to create an exploitable asymmetry. My premise is that as long as the cavities taper smoothly into fissures and capillaries of sub atomic geometry the fractional gas can become further fractionalized and migrate into these relativistic confines as long as it remains in the center of the field and does not approach the cavity walls – If it slips out of the field it should rapidly translate through the fractionalized states and be rapidly squeezed out of the cavity by the confining walls. The confusion is that the Casimir plates modify both inertial frames- segregating energy density differently inside vs outside the cavity between as mentioned by Zofia Bialynicka-Birula in her paper Cavity QED http://th-www.if.uj.edu.pl/acta/vol27/pdf/v27p2409.pdf. This abrupt breach in isotropy is unlike any other macro phenomenon in nature. She also makes a point similar to yours regarding radioactive decays but based instead on spontaneous emission of Yb atoms in a mirror resonator being either enhanced or inhibited dependent on conditions.

Scott Smith [mailto:[email protected]] Sent: Tuesday, September 06, 2011 12:34 AM To: [email protected]; Roarty, Francis X; Fran Roarty Subject: EXTERNAL: Time-Frame-Based Casimir Effect Fran, I think this is part of the difference between cavities that exhibit "negative" internal pressure or "positive" internal pressure. If we start by assuming that Lorentz Invariance applies to nanocavities then, at first, we expect the same pressure inside the cavity as outside the cavity, except for one little detail: Casimir Plates actually move! How can this be? Clearly, if we are correct, the pressure actually is the same in each time frame, but faster time means more instances of impulse as counted from a slower time frame; this gives us a positive pressure cavity. If time passes slower inside the cavity, then we have a "negative pressure" cavity. In other words, the time change is what is actually causing the Casimir Effect. Therefore, a cavity with a U-shaped cross section of the right materials, size and proportions can probably be designed so as to experience equal forces on its ceiling as on its roof, but at different rates of time. Therefore, a properly designed cavity will experience a net force. What do you think?Scott,
