SPACE - TIME can be permanently
warped by the gravitational waves that constantly ripple through it.

Although the
gravitational waves are incredibly weak — only enough to
warp the distance between Earth and the Sun
by the width of a hydrogen atom — LIGO's instruments are extremely sensitive.
My talk on a far more remote subject, «
Gravitational Waves From
Warped Extra-Dimensional Geometry,» was almost delayed
by a tied score until Beckham sent Ecuador out of the running.
LIGO's instruments are designed to detect passing
gravitational waves by measuring minuscule expansions and contractions of space - time —
warps as little as one - thousandth the diameter of a proton.
Another experiment there, the South Pole Telescope, reported finding B - mode polarization last year, although the signal it saw was at a different angular scale across the sky and was clearly due to the known process of
gravitational lensing (a
warping of light caused
by massive objects) of the CMB
by large galaxies, rather than the primordial
gravitational waves seen here.
