"Astronomers may peer deep into the cosmos to study mysterious black holes, but would you believe there are "black holes" right here on Earth?
A new study by scientists at the Swiss university ETH Zurich and the University of Miami shows that, mathematically speaking, large ocean eddies behave much like black holes. The watery vortices break off from currents and have their own "coherent" boundaries, as black holes do. Also like black holes, they swallow anything that gets too close and allow nothing to escape.
"The photon spheres around black holes have the property that anything (except light) is sucked into the black hole through them," study co-author Dr. George Haller, professor of non-linear dynamics at ETH Zurich, told The Huffington Post in an email. "Similarly, the eddy boundaries we find have the property that anything that floats on the ocean surface (except water) is sucked into the eddy through them."
The eddies can last a year or two, Haller said, though most peter out after a few months."
