## 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

## Inspiration

Dark-heaving—boundless,
endless, and sublime,
The image of eternity—
the Throne of the Invisible...

From Lord Byron's Childe Harold's Pilgrimage
Canto IV,
