Story summary

Physicist Slava Turyshev's paper tackles the "Great Disconnect" between cosmological observations and solar system physics concerning dark energy and dark matter.
Instruments show no dark energy effects in the solar system, despite its cosmic influence.
Two models explain this: the "chameleon" model, which varies with matter density, and the Vainshtein model, which suppresses the force's effects.
Turyshev argues that without a falsifiable theory, solar system experiments may be ineffective.
He calls for sensitive instruments in future missions to investigate these theories and enhance understanding of dark energy.
