This New Idea Could Explain the Laws of Nature

A new theoretical framework argues that the universe’s fundamental “constants” may have drifted through random changes early on, and that only certain combinations would settle into long-lived, stable pockets—potentially explaining why gravity, electromagnetism, particle masses, and even the speed of light look the way they do today. The central claim is that if the laws of nature are allowed to mutate in a controlled mathematical sense, the dynamics can naturally produce ordered spacetime with matter properties matching what observers infer now, without requiring a single, finely tuned starting point.

The paper’s mechanism does not let every aspect of physics evolve freely. Instead, it treats the quantities usually treated as constants—such as the strength of gravity, the electromagnetic interaction strength, the masses of particles, and the speed of light—as variables that can change. It goes further by suggesting that, in the early universe, the speed of light might have been different from the speed of gravitational waves, even though Einstein’s framework treats them as fixed and equal in the present day.

Those changes are constrained by a key physical problem: varying the constants generally breaks conservation laws, especially energy conservation. In the framework, that “violation” is not a bug but a diagnostic—regions of parameter space where the constants keep changing rapidly correspond to scenarios with rampant creation of matter and other pathologies. By contrast, the model identifies conditions under which the mutation rate effectively drops, allowing the constants to become nearly stable.

The authors describe stability using criteria tied to both geometry and causality. Stable pockets are associated with an ordered spacetime that can curve under gravity, while avoiding spontaneous creation of matter and avoiding non-local, effectively infinite-speed interactions across the universe. A central intuition is borrowed from a sand-and-sound analogy: if “constants” are like grains scattered on a plate and a speaker shakes the plate, the grains jump around when the system is strongly driven. In regions where the plate barely moves, the grains accumulate—mirroring how the model’s dynamics favor parameter sets that are unlikely to keep changing.

The framework is presented as a cousin to earlier “cosmological natural selection” ideas associated with Lee Smolin, where black holes seed new universes with different constants. Here, the new work does not invoke black holes and does not generate new universes; it instead assumes that constants can vary through some unspecified underlying process. The payoff is a statistical explanation for why conservation laws and causality appear to hold so cleanly now.

The discussion also notes that the authors do not claim our universe is unique in its constant values—only that the dynamics favor stable regions. Whether the mathematical setup can be connected to a concrete early-universe mechanism remains an open question, but the proposal offers a fresh route to the long-standing puzzle of why the laws of nature are so finely behaved.
