A black hole is a gravitational "soliton": an object made from spacetime curvature, with the curvature produced by the curvature's own energya remarkable, nonlinear phenomenon. We have known this for several decades. However, we have not understood how spacetime curvature behaves when, not only is it nonlinearly strong, but it is also highly dynamical: the dynamics of spacetime geometry, or "Geometrodynamics".
In this lecture, Thorne will describe what we have learned about Geometrodynamics in recent years, much of it via numerical simulations on computers. The discoveries include, among other things, vortexes of twisting space that interact with each other in surprising ways, and chaotic and shockwave behaviors of spacetime curvature near singularities inside black holes (which play a role in the recent science fiction movie Interstellar). Thorne will also describe the prospects to test Geometrodynamics via observations of gravitational waves from colliding, spinning black holes. << Kip Thorne ±³¼ö Open KIAS ´ëÁß °¿¬ >> ÀÏ½Ã : 2015³â 5¿ù 21ÀÏ(¸ñ) ¿ÀÈÄ 7½Ã Àå¼Ò : °íµî°úÇÐ¿ø 1È£°ü 1Ãþ ´ë°´ç Á¦¸ñ : The Science of Interstellar
