Physicists at MIT have developed a theoretical technique inspired by the film Interstellar to send messages backwards in time using quantum entanglement. The approach mimics closed time-like curves and surprisingly improves communication through noisy channels. While actual time travel remains impossible, the idea could enhance conventional systems.

Two precise experiments have agreed on a proton radius of about 0.84 femtometres, aligning with a surprising 2010 measurement and resolving a long-standing puzzle in particle physics. Researchers used lasers to study electron transitions in hydrogen atoms. The findings, published in Nature and Physical Review Letters, boost confidence in the smaller proton size.
