</div>Indeed. It is worth remembering that the diameter of a circle is a full<br>
1.5708 (PI/2) times shorter than half its circumference, so if you can get<br>
the communication *through* the earth, you can make the latency 37% lower<br>

<br>The data come from a 1300-metric-ton particle detector named Oscillation
Project with Emulsion-tRacking Apparatus (OPERA). Lurking in Italy's
subterranean Gran Sasso National Laboratory, OPERA detects neutrinos
that are fired through the earth from the European particle physics
laboratory, CERN, near Geneva, Switzerland. As the particles hardly
interact at all with other matter, they stream right through the ground,
with only a very few striking the material in the detector and making a
noticeable shower of particles.<br><br>Udi<br><br></div>
