Have we seen a white hole?By Deborah Byrd in SPACE | May 27, 2011
Are some gamma-ray bursts – such as GRB 060614 – a sign that white holes exist after all?http://earthsky.org/space/have-we-seen-a-white-holeIn late May 2011, Physorg
reported on a paper by Alon Retter and Shlomo Heller, suggesting that a known gamma-ray burst GRB 060614 might have been a white hole.
A black hole, by definition, is a huge mass in a small space. Its gravity is powerful. Light cannot escape it. Hence, a black hole’s blackness.
White holes are the theoretical opposite of black holes. As black holes draw in surrounding stars, dust, passing spaceships – whatever comes too near – so white holes, by definition, would radiate light. Matter can and would escape from white holes into the universe. Both white and black holes were entirely theoretical several decades ago, but now many actual astronomical objects are associated with black holes. Even our home galaxy, the Milky Way, is thought to have a black hole at its heart.
