Here, we give a brief introduction to the No-Rush Theorem of the Theory of Entropicity (ToE), where we state that "Nature cannot be rushed," so that no interaction in nature can proceed instantaneously.
No physical interaction can occur instantaneously; every process requires a finite, nonzero duration; implying that Nature cannot be rushed. [1][2][7][8][9]
Field Promotion
Traditionally, entropy S is a global quantity defined for systems in or near equilibrium. ToE promotes entropy to a spacetime-dependent scalar field S(x).
Couplings and Dynamics
Gradients
and time derivatives
appear directly in the equations of motion for matter and geometry, sourcing forces and mediating interactions analogously to the electromagnetic potential or the gravitational metric.
Finite Interaction Time
Because interactions proceed via the exchange or redistribution of entropy[7][8][9]—through informational currents, microscopic reconfigurations, or entropic gradients—they cannot “turn on” in zero time.
Minimum Entropic Interval
There exists a lower bound
, determined by the intrinsic “stiffness” of the entropic field[11][12] (often linked to a Fisher-information term in the action), below which no causal influence can propagate.
Causality and Speed Limits
Provides an entropy-based origin for why no influence can travel faster than a maximum speed, complementing relativity’s light-cone structure.
Gravity and Inertia
Bodies respond not only to spacetime curvature but also to the finite “ramp-up” time of entropic forces, potentially modifying inertial behavior at very small scales.
Quantum Processes and the Arrow of Time
Embeds irreversibility at a fundamental level. Quantum transitions, measurements, and decoherence processes require a nonzero duration, reinforcing the unidirectional flow of time.
Decoherence in Open Quantum Systems
Quantum coherence[13] is lost over finite timescales as systems entangle with their environment—an entropy-driven process.
Entropic Forces
Similar to how entropy gradients drive polymer elasticity or Verlinde’s[14] emergent gravity, the No-Rush Theorem ensures these gradients cannot act instantaneously.
Information-Theoretic Limits
The minimum interaction time aligns with the time needed to transfer or distinguish quanta of information, linking ToE to information-geometry and Fisher information.[15][16]
Challenging Instantaneous Assumptions
Many idealized models—instantaneous collisions, ideal springs, certain gauge approximations—assume zero-time interactions. The No-Rush Theorem treats these as approximations valid only when
is negligibly small compared to experimental timescales.
Experimental Predictions
Subtle delays or frequency-dependent response times in high-precision tests of fundamental forces could reveal the finite interaction interval predicted by ToE.
The No-Rush Theorem elevates the principle “nothing happens instantly” into a precise, quantifiable dictum: the entropic field’s dynamics enforce a strict, nonzero lower bound on all interaction times, reshaping our understanding of causality, force mediation, and irreversibility across physics.
