This discussion focuses on the concept of randomness in a universe with a limited number of particles, specifically addressing how randomness evolves as the number of particles increases from one to four. It highlights that, according to quantum mechanics (QM), a universe with a small number of particles evolves under the Hamiltonian related to their interactions, rendering the notion of measurement—and thus randomness—meaningless without a macroscopic measuring device. This leads to a deeper exploration of the measurement problem in quantum mechanics.
PREREQUISITESPhysicists, quantum mechanics students, and researchers interested in the foundational aspects of quantum theory and the nature of randomness in particle interactions.
As far as QM is concerned, a universe with a small number of particles will evolve under the Hamiltonian associated with their mutual interaction. Without a macroscopic measuring device, the question of a measurement of the particles is meaningless. In that sense there is no randomness.shivakumar said:TL;DR Summary: finding randomness in single particle universe and understand randomness in nature
how will randomness of particle be in one particle universe? how will it evolve with two, three or four particle based universe?
