Q.  Is it true that nothing can escape from a Black Hole, not even light?

A.  Not true. In fact, huge amounts of matter and energy are continually emitted from Real Black Holes, those found in the real Universe.

Q.  But hasn't it been proved mathematically that nothing can escape from a Black Hole?

A.  There is such a formula, but it only applies to Concept Black Holes, as envisaged in theory.

Q.  What's the difference between Real and Concept black holes?

A.  Concept Black Holes are not rotating. Real Black Holes rotate extremely rapidly.

Q.  What does the formula say?

A.  The formula gives the Schwarzschild Radius of the Event Horizon, beyond which nothing in a stationary Black Hole can escape.

Q.  Where can details of Real Black Holes be found?

A.  Look at XT805: What's inside Real Black Holes?.
