univeral theory Posted July 2, 2013 Author Share Posted July 2, 2013 (edited) A classical model that explains and quantifies the effects of gravity as being a geometric property of space-time, as opposed to mechanical forces between bodies. and what does this GR model predicts or explains physically?

Markus Hanke Posted July 3, 2013 Share Posted July 3, 2013 and what does this GR model predicts or explains physically? It models gravitational interactions between bodies. Link to comment Share on other sites More sharing options...

Markus Hanke Posted July 6, 2013 Share Posted July 6, 2013 what is gravitation according to GR? GR basically states that the presence of energy and matter is equivalent to changes in the geometry of space-time, in that this geometry is no longer flat but possesses intrinsic curvature. This curvature manifests as gravity, because two initially parallel-moving test particles, when crossing through a region of space-time with curvature, will start to approach each other ( this is called geodesic deviation, and forms the basis of GR's maths and physics ). So in short - in GR, gravitation is a manifestation of the curvature of space-time itself. Link to comment Share on other sites More sharing options...
