As with all physical simulations, realistic 3D computations require "Teraflop" (10^12 operations per second) performance
|
| 2 |
Numerical Relativity just solves the "trivial" Einstein equations G?? = 8?T?? with indices running over 4 dimensions

| 3 |
Apply to collision of two black holes which are expected to be a major source of gravitational waves for which US and Europe are building major detectors
|

Unique features includes freedom to choose coordinate systems (Gauge freedom) in ways that changes nature of equations
|
| 5 |
Black Hole has amazing boundary condition that no information can escape from it.
-
Not so clear how to formulate this numerically and involves interplay between computer science and physics
|
| 6 |
At infinity, one has "simple" (but numerically difficult) wave equation; near black hole one finds very non linear system
