- From ergo- + -sphere. (Wiktionary)
“Things change though for the accretion disk material which enters the ergosphere of the black hole.”
“But the black hole the enemy base was orbiting was actually a (literally) post-singularity civilization that absorbed all information that reached its ergosphere, and everything after a certain point in the battle happens in a computerized civilization.”
“Within the ergosphere, space-time is dragged around faster than light — general relativity forbids material objects to travel faster than light (so does special relativity), but allows regions of space-time to move faster than light relative to other regions of space-time.”
“The ergosphere of black hole is bounded by on the outside, an oblate spheroid, which coincides with the event horizon at the poles and is noticeably wider around the “equator”.”
“The ergosphere is an oblate spheroid region outside of the event horizon, where objects cannot remain stationary.”
“Objects and radiation can also escape from the ergosphere.”
“Rotating black holes are surrounded by a region of spacetime in which it is impossible to stand still, called the ergosphere.”
“Objects and radiation (including light) can stay in orbit within the ergosphere without falling to the center.”
“The motion of galaxies by the outward motion of points of space is a form of frame dragging, similar to the Penrose-Kerr effect of particles moved inside the ergosphere of a rotating black hole.”
“You are in a region (ergosphere) where in order to remain stationary you have to effectively travel faster than light, which is impossible.”
