Einstein-Rosen-bryggor kan koppla samman spegelversioner av tiden

Ny forskning tolkar Einstein-Rosen-bryggan som en koppling mellan två tidsriktningar snarare än en rumslig genväg. Studien antyder att detta perspektiv skulle kunna lösa informationsparadoxen för svarta hål och peka mot ett universum som existerade före Big Bang. Den publicerades i tidskriften Classical and Quantum Gravity.

Fysikerna Enrique Gaztanaga, K Sravan Kumar och João Marto argumenterar för att 1935 års Einstein-Rosen-brygga aldrig var menad att beskriva ett genomkorsbart maskhål. Istället menar de att den representerar en matematisk länk mellan två symmetriska kopior av rumtiden, där var och en har en motsatt tidsriktning. Denna tolkning uppstår genom att tillämpa moderna kvantidéer på de ursprungliga ekvationer som kopplar samman gravitation och kvantfält.

Physicists uncover tiny flaw in time from quantum collapse models

An international team of physicists has found that quantum collapse models, potentially linked to gravity, introduce a minuscule uncertainty in time itself. This sets a fundamental limit on clock precision, though far below current detection levels. The research, published in Physical Review Research, explores ties between quantum mechanics and gravity.

Researchers propose quantum method for messaging into past

30 april 2026 Rapporterad av AI

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.

Scientists detect oval orbit in black hole-neutron star merger

Astronomers have uncovered evidence that a black hole and neutron star merged while following an unusual oval-shaped orbit, challenging expectations of circular paths in such events. The discovery comes from a reanalysis of gravitational wave data from the event known as GW200105. This finding suggests the system formed in a dynamic stellar environment.

Study explores quantum clocks ticking at multiple speeds

18 maj 2026 Rapporterad av AI

Physicists have published research proposing that a single clock could tick both faster and slower at the same time due to quantum effects. The work combines relativity and quantum mechanics in a novel way. Researchers say advances in atomic clock technology may soon allow the idea to be tested in the lab.
