Researchers assume they can trust their GUT –
that is their Grand Unified Theory.
This simple answer is close, they think, but
the resolution’s still a bit bleary.
They’ve linked electromagnetic with weak,
on their way to full unification
but, for final culmination, must seek
the gravity of the situation.
They trust they’ll find the graviton one day,
through their particle acceleration.
Without this carrier to show the way,
they’re lacking complete illumination.
And thus they hesitate to claim they know,
since, still in the dark, they may stub their TOE.
