The quantum theory of the multiverse, proposed in the 1950s, suggests that reality constantly divides into parallel universes due to quantum interactions. In addition to being intriguing, this interpretation faces significant challenges.
Recently, Sandu Popescu e Daniel Collinsphysicists at the University of Bristol, questioned one of the main arguments in favor of quantum theory of the multiverse (IMM) by investigating the conservation of physical properties, such as angular momentum, in quantum events.
Conservation laws, such as that of energy, are fundamental in physics – stipulating that things can neither be created nor destroyed, but only converted into different forms.
I already said Antoine-Laurent de Lavoisier“in Nature, nothing is created, nothing is lost, everything is transformed”. However, quantum theory apparently defies this theory, as in the case of particles in superposition states.
As explained by , before a measurement, a particle can be in multiple states simultaneously, but, when measuring, only one state is observed. This transition appeared to violate conservation laws, suggesting that properties such as angular momentum “appeared out of nowhere”.
Popescu and Collins re-examined this question and demonstrated that Quantum conservation can be maintained if we consider the “prepper”i.e. the device that places particles in superposition states.
The researchers discovered that the primer and the particle interact to maintain the total balance. For example, when measuring the angular momentum of a particle, corresponding changes occur in the preparer, ensuring that conservation applies even in isolated events.
This result challenges the need for parallel universesproposed by IMM to solve quantum paradoxes, more than 65 years ago.
Researcher Daniel Collins told New Scientist that this discovery reinforces the importance of avoiding ideological approaches in quantum physicsencouraging a deeper investigation of the theoretical foundations.
Popescu and Collins’ research also opens doors to better understanding reference structures in quantum measurements. These structures are defined by the attributes of the preparer and play a crucial role in maintaining symmetry, a fundamental principle of physics.
The link between symmetry, conservation laws and frames of reference suggests a new vision of the cosmos of a unique reality constructed in a relational wayas opposed to the IMM’s multiplicity of worlds.
Although controversial, Popescu and Collins’ research offers new insights into resolving quantum paradoxes and bringing us closer to a deeper understanding of quantum mechanics.
