Geon (physics) - Wikipedia In general relativity, a geon is a nonsingular electromagnetic or gravitational wave which is held together in a confined region by the gravitational attraction of its own field energy They were first investigated theoretically in 1955 by J A Wheeler , who coined the term as a contraction of "gravitational electromagnetic entity"
Geons | Phys. Rev. - Physical Review Link Manager Such gravitational-electromagnetic entities, or "geons"; are analyzed via classical relativity theory They furnish for the first time a completely classical, divergence-free, self-consistent picture of the Newtonian concept of body over the range of masses from ∼ g to ∼ g
John Wheeler, relativity, and quantum information gravitational geon: a bundle of gravitational waves held to-gether gravitationally Such a geon would pull on its sur-roundings, thereby exhibiting mass, but it would not contain any material mass Mass without mass, he called it The geon in one sense was a dead end As Wheeler soon realized, the conditions for creating a geon almost certainly
[gr-qc 9610074] Gravitational Geons Revisited - arXiv. org Abstract: A careful analysis of the gravitational geon solution found by Brill and Hartle is made The gravitational wave expansion they used is shown to be consistent and to result in a gauge invariant wave equation
Galactic Geons: Revisiting the Dark Matter Paradigm These findings suggest that geons could serve as both the gravitational scaffolding for galaxy formation and a replacement for cold dark matter, unifying multiple cosmological phenomena under a single theoretical framework 1 Introduction
Geons - INSPIRE-HEP Such gravitational-electromagnetic entities, or "geons"; are analyzed via classical relativity theory They furnish for the first time a completely classical, divergence-free, self-consistent picture of the Newtonian concept of body over the range of masses from ∼1039 g to ∼1057 g
Massive Graviton Geons and Dark Matter - Indico GWs have their gravitational energy! GWs (=perturbations) themselves change the background geometry Is it possible to realize self-gravitating gravitational waves? The original idea of “geon” is a gravitational electromagnetic entity = a realization of classical “object” by gravitational attraction GC2018@YITP Wheeler, 1955
Geon Wheeler: from nuclear to spacetime physicist - Springer We provide an account of John Wheeler's transition from his work on elementary particle physics (in which particles provided the ultimate ontology in his worldview), to his work on gravitation and general relativity (in which spacetime geometry was the ultimate object out of which all other things were composed)
Geons - gwern. net Such gravitational-electromagnetic entities, or "geons"; are analyzed via classical relativity theory They furnish for the first time a com-pletely classical, divergence-free, self-consistent picture of the Newtonian concept of body over the range of masses from ~103' g to 10'7 g
