NASA scientist Slava Turyshev proposes fifth force or dark energy in solar system

Turyshev, from NASA's Jet Propulsion Laboratory, outlines two screening models—chameleon and Vainshtein—that could conceal such forces, with the Vainshtein radius for the Sun estimated at 400 light years.
He argues that current solar system experiments confirm general relativity, but new, more sensitive missions and falsifiable predictions are needed to detect any hidden force locally.
The research highlights a 'Great Disconnect' between cosmic and local physics, suggesting that targeted experiments could eventually reveal new physics and reshape our understanding of gravity and dark energy.
If a fifth force is hiding in our solar system, what kind of mission could finally unmask it?
With new data showing gravity is normal, is the cosmic 'Great Disconnect' even a real phenomenon?
DESI's map hints that dark energy is changing. What does this mean for the universe's ultimate fate?
How can dark energy be evolving if gravity on the largest scales still follows Einstein's classic rules?
Is the search for a fifth force a path to breakthrough or just a modern-day hunt for ether?
