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
