The quantum state at t=0, or the moment of the big bang, can be understood through two primary interpretations. One perspective posits that the quantum state existed in a state of superposition, where all possible states of the universe coexisted simultaneously. Alternatively, it can be argued that there was no definite state at that moment, as the wave function of the universe had not yet collapsed. Both interpretations highlight the complexities of applying quantum mechanics to the origins of the universe.
PREREQUISITESPhysicists, cosmologists, and students of quantum mechanics interested in the foundational concepts of the universe's origins.
QuantumClue said:There are two ways to view it. We need to apply quantum mechanics to the very first instant.
You can say the quantum state was in a state of superpositioning, meaning that every possible state of the universe arose side-by-side. A different way is to state there was no definite state, considering alone the wave function of the universe had no collapsed.
