If gravity is the shape of spacetime, why is there the need for a graviton messenger particle? Space, Time and Gravitation: An Outline of the General Relativity Theory (Cambridge Science Classics)Arthur S. General relativity describes gravity as a curvature of space-time. After seeing some heavy stuff on Relativistic Theory of Gravitation (RTG) in the last post, we come to yet another book on General Relativity (GR) which is titled Space Time Gravitation by Yu. OK so I've had a crazy idea about the universe for a while now and I think I'm just going to go ahead and post it online for all to see and comment. If space-time expresses gravity on the subatomic level and “anti-gravity” on the cosmological level, then we only have to find a missing minus sign in our equations. The nature of gravitation and electromagnetism has been determined. Spacetime, Geometry and Gravitation book download. According to Einstein's general theory of relativity, first published in 1915, the phenomenon we experience as gravitation can be interpreted purely geometrically. Download Spacetime, Geometry and Gravitation Gravity emerges not as an actual physical force but as a consequence of space-time geometry. A passing gravitational wave would then produce a small ripple in spacetime causing a change in mirror spacing, shifting the location where the particle is trapped. Friday, 22 March 2013 at 18:52. If electromagnetism the result of electromagnetic polarisation of the quantised space-time, gravitation is caused by its deformation (distortion). In other words, objects in the fabric of space-time bend it so as to create gravity. We write the line element describing the interior space-time of a spherically symmetric star collapsing under the influence of self-gravity (in standard coordinates , , , and ) as where, , , and are yet to be determined. Gravitational lensing occurs because spacetime is curved around all objects in the universe. That's what Einstein taught us: that mass indents spacetime, creating depressions. One needs the full theory of quantum gravity but it's generally believed that it can't help us to eliminate the singularity as a violent and irregular end of the spacetime, anyway. Space-time and gravitation… OK so I've had a crazy idea about the universe for a while now and I think I'm just going to go ahead and post it online for all to see and comment on.
