| To penetrate the
mysteries of gravity, a team of scientists is preparing the most delicate space
experiment ever devised.

If the gods of physics smile upon Francis Everitt, sometime before the end of this
decade four near-perfect quartz spheres spinning away in supercooled isolation 400
miles above Earth will experience an infinitesimal change in the direction of their
spin. It will be a change so absurdly small- the width of a hair is huge by
comparison- that for a long time it was thought impossible to measure. No less
audacious is what Everitt hopes to prove-or disprove-by quantifying this minuscule
movement: Einstein’s general theory of relativity.
It’s an undertaking that, not surprisingly, has been decades in the making,
and it has drawn some of the brightest thinkers in the fields of physics and engineering.
It has also attracted its share of criticism, both from the scientific community
and from NASA, which is providing most of the funding. Nonetheless, project director
Everitt has managed to counter every challenge with compelling evidence of the
program’s merit. To put it plainly, Everitt is poised to either confirm or overthrow
the entire foundation of modern cosmology.
