Physicists discover how to extract data from multiverse

Information could hypothetically pass from one parallel universe to another - physicist Maria Violaris has proposed an experiment to test this possibility, according to Popular Mechanics.
Conditions for information leakage between universes
As part of an adaptation of the classic "Wigner's friend" thought experiment, Maria Violaris studied the behavior of two copies of the same observer existing in quantum superposition.
The model envisages the possibility of signal transmission under strict conditions:
- Presence of a super-observer: To establish contact, an external operator is required who completely isolates the internal system and manipulates its quantum state.
- Memory erasure: The sender of the message in their own universe must completely lose memory of the very fact that the record was created.
- Sudden insight effect: For the recipient in the parallel branch, the information appears without any local source or backstory.
Scientific skepticism and the "multiverse arbitrage" hypothesis
The idea of theoretical data leakage has sparked discussion about "multiverse arbitrage" - the hypothetical use of information from other realities (such as stock quotes) for rapid enrichment.
However, scientists point out significant limitations:
Personality replacement effect: According to quantum computing expert Scott Aaronson, in the described process, information does not move between worlds.
Instead, the observer who created the message is erased from their branch and replaced by a copy they did not create.
Lack of agency: Participants in the experiment cannot send data at will, and the external controller does not have access to the content.
Prospects
Since humans are not in a state of quantum superposition, direct data transfer between human copies in the multiverse is impossible.
Researchers hope to test the hypothesis using future technologies.
Which ones?
Quantum AGI: In 10–20 years, scientists expect the emergence of quantum computers capable of running artificial general intelligence in a state of superposition.
Digital observers: AI algorithms within quantum systems will be able to model alternative scenarios of events and consolidate results into a single decision-making system.
Consciousness barrier: Conducting the experiment will require creating digital intelligence with full consciousness and controlled memory, which currently remains an unreachable technological frontier.
