A near-light-speed enclosing energy field as a positron source and candidate time-dilation capsule

Abstract Accelerating a macroscopic mass to relativistic speed, or creating a black-hole-like gravitational field, is infeasible with current technology. We examine a conceptual alternative in which a large structure is fully surrounded by a closed energy shell moving near the speed of light—a 15 MV electron arc with a co-propagating 20 keV laser circulating in an evacuated gap between two capsules—and ask whether its interior could behave as a time-dilation domain. For the 15 MV arc we obtain a Lorentz factor γ = 30.35, corresponding to an interior elapsed time of ~ 119 s per external hour. The same arc generates positrons by pair production at a tungsten surface; we estimate ~ 5.9×10 20 positrons (~ 542 ng) produced in a 1-hour run, of which Surko-type buffer-gas traps could capture ~ 5.4 ng undamaged. Antiprotons cannot be produced (15 MeV is far below the 1.9 GeV threshold). We compute the energy balance (15 kWh in, 0.27 kWh out; ~55× loss) and, as a speculative commercial scenario, include a hypothetical $3 million-per-hour revenue attributed to the pig owner's time-travel, yielding a payback of ~ 50–217 hours. The time-dilation interpretation rests on an unresolved rotating-frame problem and the pig revenue is unproven. This is a conceptual proposal; no experimental data are reported. Special relativity predicts time dilation for systems in relativistic motion 1 , verified by muon lifetimes and satellite-clock corrections 2 . Exploiting this for a macroscopic volume by accelerating the volume itself is energetically inaccessible. We instead consider supplying the relative motion through a surrounding field rather than the body. The concept—the energy-field configuration—drives a closed shell of charged particles and photons around a stationary inner capsule at near-light speed in an evacuated gap. Within the principle of relativity, a field streaming around the capsule is locally hard to distinguish from the capsule moving through the field; we adopt this as a working hypothesis while stressing that the shell follows a rotating, non-inertial trajectory whose rigorous treatment requires the Sagnac effect and general relativity (Limitations). A concrete corollary is positron production: the high-energy electron arc generates positrons by bremsstrahlung and pair production at a high-Z surface 3 . The configuration thus couples a time-dilation hypothesis to a positron source.
