Frame-dragging vortexes and tidal tendexes attached to colliding black holes: visualizing the curvature of spacetime.
نویسندگان
چکیده
When one splits spacetime into space plus time, the spacetime curvature (Weyl tensor) gets split into an "electric" part E(jk) that describes tidal gravity and a "magnetic" part B(jk) that describes differential dragging of inertial frames. We introduce tools for visualizing B(jk) (frame-drag vortex lines, their vorticity, and vortexes) and E(jk) (tidal tendex lines, their tendicity, and tendexes) and also visualizations of a black-hole horizon's (scalar) vorticity and tendicity. We use these tools to elucidate the nonlinear dynamics of curved spacetime in merging black-hole binaries.

متن کاملCharged Particle Trajectories in a Toroidal Magnetic and Rotation-induced Electric Eld around a Black Hole
Trajectories of charged particle in combined poloidal, toroidal magnetic eld and rotation-induced unipolar electric eld superposed in Schwarzschild background geometry have been investigated extensively in the context of accreting black holes. The main purpose of the paper is to obtain a reasonably well insight on the e ect of spacetime curvature to the electromagnetic eld surrounding black hol...
متن کاملColliding Kaluza-Klein Bubbles
We construct an exact solution describing the collision of two Kaluza-Klein “bubbles of nothing” in 3+1 dimensions. When the bubbles collide, a curvature singularity forms which is hidden inside an event horizon. However, unlike the formation of ordinary black holes, in this case the spacetime resembles the entire maximally extended Schwarzschild solution. We also point out that there are inequ...
