Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make …

Oct 14, 2023 · Researchers at the University of Cambridge have demonstrated that they can mimic what would happen if one could travel back in time by playing with entanglement, a …

May 29, 2024 · Time loops have long been the stuff of science fiction. Now, using the rules of quantum mechanics, we have a way to effectively transport a particle back in time – here’s …

May 21, 2025 · Quantum time travel is a wild ride through the world of particles, paths, and paradoxes. While we might not be ready to jump into a time machine just yet, the journey into …

Feb 8, 2025 · So far, physicists have thought that time travel causes insurmountable paradoxes, but now three quantum physicists from the UK, Switzerland, and the US have found a loophole …

Sep 29, 2024 · Wormholes are hypothetical passages through space that have been proposed by physicists as potential shortcuts between distant points in the universe. Scientists suggest that …

May 29, 2024 · Using quantum systems, researchers can create scenarios where particles, such as electrons or photons, can theoretically be sent back in time. This is done through intricate …

Mar 19, 2025 · Wormholes, cosmic strings, and quantum theories hint at mechanisms that might permit time travel under extraordinary conditions. Yet enormous challenges remain—practical, …

Oct 12, 2023 · Researchers at the University of Cambridge have shown that by manipulating entanglement – a feature of quantum theory that causes particles to be intrinsically linked – …

Oct 21, 2024 · The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the …
