Cosmic balloons.
Cosmic balloons, consisting of relativistic particles trapped inside a spherical domain wall, may be created in the early universe. We calculate the balloon mass M as a function of the radius R and the energy density profile, ρ(r), including the effects of gravity. At the maximum balloon mass 2GM/R ≈ 0.52 for any value of the mass density of the wall. [email protected] Domain walls may fo...

متن کاملMagma balloons or bombs?
To the Editor — Detailed analysis of volcanic materials1 allows the study of eruptions that have not been witnessed directly. Rotella et al.2 undertake the challenge of interpreting submarine volcaniclastic deposits around Macauley Volcano, part of the Kermadec Arc in the southwest Pacific Ocean. They propose a ‘Tangaroan’ eruption style, based on the textural characteristics of dredged pumice ...
متن کاملStability of Lobed Balloons
This paper presents a computational study of the stability of simple lobed balloon structures. Two approaches are presented, one based on a wrinkled material model and one based on a variable Poisson’s ratio model that eliminates compressive stresses iteratively. The first approach is used to investigate the stability of both a single isotensoid and a stack of four isotensoids, for perturbation...
متن کاملHydroxyethyl methylacrylate and latex balloons.
Room-temperature vulcanizing silicone and homopolymers of 2-hydroxyethyl methacrylate (HEMA) have been used to permanently inflate detachable balloons [1] . HEMA is preferred over silicone because it is less viscous and is water soluble. Goto et al. [2] described a commercially available (HEMA A, lnterventional Therapeutics, S. San Francisco, CA) polymerizing substance that includes HEMA as the...
