Is This a Black Hole or a New Type of Star? - by BrianKoberlein
A soliton is a self-reinforcing wave effect. They were first observed as a rise of water traveling within a canal. Unlike regular waves, they maintain their shape for long periods of time, almost as if they were an object. Water wave solitons have been studied in the lab since the late 1800s, and optical solitons were first created in glass fibers in the 1980s. They are a well-known physical phenomenon. A topological soliton is a mathematical description of this effect.
