Joos and Zeh (1985) showed that macroscopic superpositions suppress coherence on timescales far shorter than dynamical evolution, meaning momentum uncertainty accumulates before Newtonian forces dominate.

Joos and Zeh(as referenced scientists in quantum mechanics): Two physicists (Dieter Joos and Wojciech Zurek) who developed influential theories about how quantum systems interact with their surroundings.
Macroscopic superpositions(as a quantum physics phenomenon): When large, visible objects exist in multiple states at the same time simultaneously—like a coin spinning in the air being both heads and tails until it lands.
Momentum uncertainty(as a quantum physics principle): The inherent fuzziness in how precisely you can know both an object's speed and position at the same time—the more exactly you know one, the less you know the other.
Newtonian forces(as classical physics concepts): The everyday physical forces (like gravity and friction) described by Newton's laws that we experience in the normal, non-quantum world.
