A new study published in Physical Review Letters explores the ER = EPR conjecture, which posits a connection between quantum entanglement and wormholes, using hydrogen atoms as a test case. Researchers, including Irfan Javed and Prof. Edward Wilson-Ewing from the University of New Brunswick, found that if the conjecture were true, it would imply alterations to the hydrogen atom's hyperfine structure and effective charge—effects that have not been observed. The hydrogen atom, known for its precise measurements, was ideal for this investigation. The researchers hypothesized that the electron's electric field could leak into a hypothetical wormhole, weakening its effective charge. However, their findings indicate that any potential effect is significantly weaker than previously estimated, at least a million times smaller than current natural estimates. The study highlights the need for more precise theoretical formulations of the ER = EPR conjecture and opens avenues for future research, including testing with heavier atoms and adapting entanglement witness experiments. These efforts could provide critical insights into the relationship between quantum theory and spacetime connectivity.
