Theoretical physicists aren't forced to field the answer to this question at this moment in space time. Does the creation of a black hole from a super massive star collapse create gravitational ripples in 4d space-time? Quantization of fermions on Kerr space-time. Subtitle: Understanding Space, Time, and Gravity. In order to describe gravity, general relativity uses the concept of curved spacetime. As its name suggests, semiclassical gravity involves a combination of quantum and classical components. This conclusion arises very simply: (i) Principle of equivalence implies that trajectories of light will be acted by gravity. Anshul wrote: Why is there gravitation? Reply Sat 25 Aug, 2012 01:40 pm. Flat space-time and negative space-time describe an environment in which the Universe is non-compact, with space extending infinitely, forever in time, in any direction. General relativity generalises special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. 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. In order to describe how Alice feels the world around her we can also use the concept of curved spacetime. I would think the quick release of. As I understand, the gravitation of general relativity in effect locally contracts spacetime, counteracting and overcoming any universal expansion of spacetime. Gravity influences and is influenced by everything that carries an energy, and is intimately connected with the structure of space-time. The following comments should be most useful to you if you already have familiarity with special and general relativity. Download: PDF (3,273 kB) Buy this article Export: BibTeX or EndNote (RIS). Many physicists believe that gravity, and space-time geometry are emergent. The theory of gravitational lensing is reviewed from a spacetime perspective, without quasi-Newtonian approximations.
