The size of a black hole as determined by the radius of the event horizon or Schwarzschild radius is proportional to the mass M through. Students calculate black hole sizes from their mass time and space distortion and explore the impact that black holes have upon their surroundings.

- 75 Mby 53 Problems A revised and expanded introduction to the basic properties of black holes using elementary algebra and geometry.
If the theory is to be believed then the curvature of spacetime is infinite within a black hole the black hole contains a singularityBut we dont know whether this is really true for black holes that exist in nature. This is often referred to as the BekensteinHawking formula. Displaystyle ell _ text P sqrt Ghbar c 3 is the Planck length. Here is the main equation for a black hole.
