The Truth About Black Holes provides an opportunity for students to research the fascinating topic of black holes and to examine the concepts of escape velocity, gravity, mass, and the speed of light as it applies to the creation of a black hole. Spectacular images provided by the Hubble Space Telescope illustrate the lesson and provide data that the students will use to hunt for black holes in the centers of galaxies. The escape velocity of a planet or star depends on its mass and radius.
Gravity is a basic force of nature created between objects that have mass.
A black hole is the result of runaway gravity that compresses mass into a singularity. Time necessary to become familiar with the lesson.
