In order to describe gravity, general relativity uses the concept of curved spacetime. According to General Relativity, the mechanism of Gravitation is the curvature of space-time around massive bodies. Quantization of fermions on Kerr space-time. The only concept you need is the simplest one: When only gravity acts upon an object, the object always move in straight line in spacetime. 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.

The theory of gravitational lensing is reviewed from a spacetime perspective, without quasi-Newtonian approximations. In order to describe how Alice feels the world around her we can also use the concept of curved spacetime. This idea is exceptionally accurate at a macroscopic scale. Many physicists believe that gravity, and space-time geometry are emergent. Description: Опубликовано Yesterday пользователем Anton Shlyakin. Einstein's general theory of relativity states that objects with mass cause a curvature in space-time, which we perceive as gravity. The amount of matter condensed in such groupings is so high that their gravity is enough to warp even the fabric of space-time, distorting the path that light takes when it travels through the cluster. Theoretical physicists aren't forced to field the answer to this question at this moment in space time. Gravity influences and is influenced by everything that carries an energy, and is intimately connected with the structure of space-time. Reply Sat 25 Aug, 2012 01:40 pm. 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.
