175 orbits!!

Feb 17 2015 
The SXS collaboration has produced the first computation of black hole
binary coalescence that is capable of following the black holes for
over 175 orbits until they collide.  Previous computations were
limited to only a few dozen orbits. The ability to track many orbits
is important for testing the post-Newtonian approximation and for
producing waveforms that cover the entire range of frequencies that
will be seen by LIGO.  See the preprint here
(http://arxiv.org/abs/1502.04953).

Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run twice as fast as that.

About SXS

The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.

The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
