When They Came Back Together

Ultracold rubidium on an atom chip.

One path held still relative to the lab. The other in free fall. Then reunited.

About eighty radians of phase. Cubic in time. The signature they wanted. Within a couple of percent.

They will not say gravity is quantum. Unification is a late mouth. No conflict is a late mouth. I will not use those.

Quantum Galileo is the instrument if you stay with the chip and the two paths. Dress if you mean the world agreed.

The leftover is the phase that sat when they came back together, and the held path against the falling one. Both sat still. Neither needs a larger name.
