Document Summary
Escape velocity: velocity needed to escape the gravitational eld of a mass v-2gm/d. There"s a certain velocity at which an object can be projected in order for it to escape earth"s gravitational eld/orbit. The faster an object is projected (faster its velocity), farther is the distance it will travel. (orbit is essentially free fall that never ends) ex. Max. speed limit: speed of light (c). As we increase mass in a particular space, hole (warp in. The deeper the hole, the more energy/escape velocity to get. Black holes create a bottomless pit: nothing can escape spacetime) will get deeper away from it, including light. They have in nite density light, nothing can move faster than it. the idea of escape velocity dark place. First proposed in 1783 (john mitchell, geologist). Idea lost until after einstein published relativity in 1916 . Singularity: regular matter/mass compressed to an in nitely small size (consistent size)
