In a new study, scientists examined whether modified expressions for black hole entropy (a measure of chaos) could serve as a source of matter for traversable wormholes. Using Morris-Thorne geometry, they considered five models: Barrow, Tsallis, Kaniadakis, logarithmic, and exponential. It turned out that different density profiles lead to different types of wormholes: some require negative energy, others are localized, and the logarithmic model even allows ordinary matter. This work shows that the microscopic laws of black holes can create exotic spacetime structures, shedding light on a possible connection between gravity and thermodynamics.
Spacetime is like a giant sheet of paper. Fold it—and distant corners come together. Poke a pencil through, and you get a wormhole, a short tunnel through the folds. But the paper wants to spring back flat, snapping the passage shut. To keep it open, you need a rare “gasket”—matter with negative energy.
Such matter emerges if you rethink entropy—the measure of disorder on that sheet. Physicists tested five modified entropy laws, originally devised to describe black holes, and each model naturally produced clumps of negative energy density, perfect for propping the tunnel open. The structure’s stability was confirmed by equations akin to balancing scales for force distribution.
Bottom line: exotic matter requires no magic—the geometry of curved spacetime itself generates it through the lens of non-standard entropy. Information and gravity are intertwined, and perhaps the secret to interstellar travel lies in the subtleties of measuring chaos.
🎯 Traversable wormholes were first proposed by [scientist:Kip Thorne]Kip Thorne[/scientist] and Michael Morris—Carl Sagan asked them to devise a realistic method of interstellar travel for his novel *Contact*.
🎬 In *Interstellar*, a wormhole leads the heroes to distant worlds—though keeping the tunnel open required mysterious matter, the very stuff this work investigates.
