About This Lesson
American physicist John Archibald Wheeler first coined the term "black hole" in 1967. Before
the adoption of the term by Wheeler, the objects now known as black holes were referred to as
frozen stars, dark stars, or collapsed stars. Black holes come in all sizes. Stellar black holes are
the result of massive stars dying. Supermassive black holes are believed to have been created
during the early Universe. Use this booklet to learn more.
