It will take 42 days for the
Large Hadron Collider
to provide us with the
Answer to Life, the Universe, and Everything
.
Between the official inauguration of the LHC on
September 10, 2008
and the first high-energy collisions experiment on
October 21, 2008
are
42
days*.
*Including the first and the last day.
BTW: How many hadrons can fit in a row?
