== Why BlackHoles@Home? ==

The two-body problem, which governs the motion of two orbiting point masses bound by gravity, can be solved on the back of an envelope in Newtonian physics. In Einsteinian gravity, the two-body problem consists of two orbiting black holes. Due to the extreme complexity of solving Einstein's equations of gravity (general relativity), it took 90 years (1915-2005) to compute the motion of two orbiting black holes, and the feat was only made possible with the aid of supercomputers. Unlike Newton's understanding of gravity, general relativity predicts that two orbiting black holes will emit gravitational waves. Since this emission saps the orbital energy from the black holes, they will inspiral and merge to form a single, bigger black hole.

BlackHoles@Home aims to reduce the cost of numerical relativity black hole and neutron star binary simulations by ~100x, through adoption of numerical grids that fully exploit near-symmetries in these systems.
