The Crooked Seed That Spawned the Universe ⚡ экспресс
Weak interactions create tiny energy differences between left- and right-handed chiral systems due to parity violation. Normally these effects are negligible, but they can be significantly amplified in collective phenomena like phase transitions. A theoretical model has been proposed describing the amplification of weak interactions during phase transitions; the amplification factor is proportional to the critical number of atoms Nc in the nucleus of the new phase. Once the nucleus reaches critical size, it grows to fill the entire system. Measuring the ratio of produced left- and right-handed chiral structures can serve as a method to determine Nc. Experiments with the formation of specific spin-chiral structures in crossed electric and magnetic fields indicate Nc ~ 10⁹–10¹⁰. An open question is whether similar amplification could operate in cosmological phase transitions, sufficiently enhancing CP-violating effects to contribute to the observed baryon asymmetry (baryogenesis).
The weak interaction—the most elusive of fundamental forces—creates a tiny imbalance between left- and right-handed versions of molecules. The difference is so small that in a solution it gets lost in thermal chaos, just as the curvature of a tiny seed goes unnoticed for a time.
But during crystallization, a seed forms first—a microscopic 'grain' of many atoms. If it reaches a critical size, the asymmetry of each molecule adds up to a mighty force. Much like a barely bent seed grows into a tree with a noticeable curve, the seed dictates the shape of the entire crystal. Experiments with electric and magnetic fields recorded an amplification of billions of times, allowing scientists to measure that critical number of atoms.
In the early universe, after the Big Bang, a series of phase transitions could have repeatedly amplified the initial difference between matter and antimatter. Thus, a microscopic asymmetry in the fabric of existence turned into a grand imbalance that decided the fate of the cosmos.
🎯 The energy difference between left- and right-handed amino acids is so tiny that it's comparable to the energy a coin gains when lifted above a table by the thickness of a single atom.
🎬 This idea echoes Ray Bradbury's story 'A Sound of Thunder,' where a crushed butterfly changes the course of history—only here, the weak interaction plays the butterfly's role.
