Gravity is easy to feel and hard to isolate.
Shrinking the source
Tabletop experiments move small masses near sensitive probes and ask whether the measured response matches known physics.
The false-signal problem
Electrostatic forces, vibration, temperature drift, and magnetic fields can all masquerade as tiny gravitational effects.
Why the work matters
The experiments are modest in size but ambitious in implication. They probe where quantum control and gravity might finally meet in the same apparatus.
