Quantum geometry

from Wikipedia, the free encyclopedia

The Geometrodynamics (or shortly Geometrodynamics ) is a physical theory as a reformulation of the theory of general relativity was intended (ART). It takes into account that the space-time curvatures are not static but dynamic , i.e. H. are constantly on the move. However, the theory was flawed and was replaced by other theories such as string theory .

Geometrodynamics was developed in 1961 by the American physicist John Archibald Wheeler . Wheeler tried to lay the mathematical foundation for quantum gravity with the theory . He introduced gravitational quanta into his theory, so-called geons , which are responsible for space-time curvatures and should influence particles with masses.

Wheeler and Charles Misner also tried to unite the theory of electromagnetism with the help of geometrodynamics with modern gravitational theory. One finding was that energy, also in the form of electromagnetic energy, can bend space-time. Because according to the ART, energy behaves like mass.

Based on mathematical calculations by Albert Einstein and Nathan Rosen , Wheeler assumed that the entire space-time is criss- crossed by tiny micro wormholes . Wheeler coined the term quantum foam . Through further calculations he came to the assumption that electromagnetic field quanta can propagate through these micro-wormholes. Because according to calculations by physicists Gunnar Nordström and Hans Reissner ( Reissner-Nordström metric ), electrical charges can exist in black holes , which is called an electrically charged black hole.
