Pontes de Einstein-Rosen podem conectar versões espelhadas do tempo

Uma nova pesquisa reinterpreta a ponte de Einstein-Rosen como uma conexão entre duas direções do tempo, em vez de um atalho espacial. O estudo sugere que essa visão poderia resolver o paradoxo da informação em buracos negros e apontar para um universo que existiu antes do Big Bang. O artigo foi publicado na revista Classical and Quantum Gravity.

Os físicos Enrique Gaztanaga, K Sravan Kumar e João Marto argumentam que a ponte de Einstein-Rosen de 1935 nunca teve a intenção de descrever um buraco de minhoca atravessável. Em vez disso, eles afirmam que ela representa um vínculo matemático entre duas cópias simétricas do espaço-tempo, cada uma com uma seta do tempo oposta. Essa interpretação surge da aplicação de conceitos quânticos modernos às equações originais que conectam a gravidade e os campos quânticos.

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

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 de maio de 2026 Reportado por IA

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.
