Time Can Still Be Tricked ⚡ экспресс
Original: "Are Petrov type-N and D spacetimes admitting CTCs valid in $$f(R,\mathcal{L}_m,\Phi,X)$$ gravity?"
Scientists put two time machine models to the test in extended gravity — and they work.

Physicists tested two time machine models in an upgraded gravity theory with a scalar field — and the time loops survived. The 'chronology protection' didn't kick in. That suggests: nature might leave a loophole for traveling to the past.
🎯 The most famous time machine in general relativity is the wormhole, proposed by [scientist:Albert Einstein]Einstein[/scientist] and Nathan Rosen. But keeping it stable requires exotic matter with negative energy.
🎬 Time travel is a sci-fi staple: from H.G. Wells' The Time Machine to the film Interstellar, where [scientist:Kip Thorne]Kip Thorne[/scientist] served as scientific consultant.
