New Neural Network Could Solve The Three-Body Problem 100 Million Times Faster. The three-body problem, one of the most notoriously complex calculations in physics, may have met its match in artificial intelligence: a new neural network promises to find solutions up to 100 million times faster than existing techniques. First formulated by Sir Isaac Newton, the three-body problem involves calculating the movement of three gravitationally interacting bodies – such as the Earth, the Moon, and the Sun. The research hasn’t yet been published , but is available to read on arXiv.org.
