Query: On the initial phenomena occurring in lead/lead collisions at
  relativistic energies   A new study of the initial phenomena occurring in the fireball should confirm
the predicted creation of a new state of nuclear matter having a lifetime of
0.17 yoctosecond and releasing an energy of 3.87 GeV. The energy-time
uncertainty relation might be connected with an up to now unsuspected
momentum-position uncertainty relation holding in a three-dimensional time.
This new point of view leads to the interpretation of the charge of a particle
as being a rotational motion in time, to a new interpretation of inertia, and
to a new interpretation of the color of a particle. The transverse momentum
observed in the study of the fireball might be the signature of this motion in
time of the charge.
