Black holes appear black for what basic reason?They appear in starless, dark areas of the Milky Way.They "shine" by blackbody radiation and are easily detected.    They are invisible and can never be detected by astronomers.Light cannot escape them.

Which statement about black holes is true?Group of answer choicesThey form from 1.4 solar mass stars.Their escape velocity is greater than the speed of light.Their event horizon is a physical surface boundary.Their main sequence mass was 1-3 solar masses.
