The holy grail of physics is to unite all of nature’s physical laws into a single, cohesive theory. It was a dream passionately pursued by Einstein nearly a hundred years ago and continues unabated to this day. 2,099 more words

#### Geon Analogues in Sourceless Gauge-Field Theories

It has been shown that there is no finite-energy non-singular solutions to the classical sourceless gauge-field equations in four-dimensional Minkowski space that does not radiate energy nor are there solutions which hold themselves together for a long time before radiating away their energy. 351 more words

#### It from Bit

If you look at the image heading for this blog (a section of the Orion Nebula), you may be forgiven for thinking that it is merely a tenuous link to the futurist tagline, or that I simply typed “striking space image” into Google in an attempt to hook new readers. 350 more words

#### Geons and Wormholes

As described by John Wheeler classical physics be regarded as comprising gravitation, source free electromagnetism, unquantized charge, and the unquantized mass of concentrations of electromagnetic field energy or geons, in these terms classical physics can be described in terms of curved empty space, and nothing more. 376 more words

#### Geon black holes and quantum field theory

A geon, short for gravitational-electromagnetic entity, was introduced in 1955 by John

Archibald Wheeler as a configuration of the gravitational field, possibly coupled to other… 670 more words

#### Topological Geons

Topological geons are topological structures which are ‘quasi-localized’ and therefore capable of behaving like particles. The relevant topology here is purely spatial and is real as opposed to virtual. 175 more words

#### Geons with spin and charge

The term geon, short for gravitational-electromagnetic entity, was introduced in 1955 by John Archibald Wheeler to denote a classical gravitational configuration, possibly

coupled to electromagnetism or other zero-mass fields, that appears as a long-lived massive object when observed from a distance but is not a… 197 more words
