Mehau Kulyk / Science SourceThe solutions to Einstein's formulas that describe a spinning black holes will not explode, even when poked or prodded.In 1963, the mathematician Roy Kerr discovered a solution to Einstein's formulas that precisely described the space-time outside what we currently call a rotating black hole. (The term wouldn't be created for...
Mathematicians would like to know if equations concerning fluid circulation can break down or "explode" in certain circumstances. Credit: Quanta Magazine.For more than 250 years, mathematicians have been attempting to "blow up" a few of one of the most important formulas in physics. Those explain exactly how liquids circulate. If they are successful, they...
One case of a particle’s movement. It begins as the red point, resting on the surface of the hand (black wavy line). It follows the blue path, escaping the hand and then moving freely through the hand-washing fluid.
