The phenomenon of déjà vu refers to the feeling of having experienced a situation or event before, even though it is actually occurring for the first time. While déjà vu is still not fully understood, there is currently no scientific evidence to support the claim that it is caused by quantum information transmitted from our multiverse-selves.
Déjà vu is commonly attributed to a temporary glitch or misfiring in the brain's memory-recall processes. It could be a result of the brain's inability to properly sort and process incoming sensory information, leading to a feeling of familiarity with a new experience.
The idea of multiple universes or a multiverse is a speculative concept in physics, originating from certain interpretations of quantum mechanics. While the multiverse hypothesis is an intriguing idea, there is currently no concrete experimental evidence to support its existence.
Given the current scientific understanding, it is more reasonable to consider déjà vu as a subjective experience related to memory and perception, rather than a phenomenon involving the transmission of quantum information from parallel universes. However, scientific knowledge evolves over time, so our understanding of déjà vu and the multiverse may change as new evidence emerges.
