Tunnels from Entropy: A New Key to Wormholes ⚡ экспресс
The entropic gravity hypothesis links geometry to thermodynamic information of microstates. The possibility of using density profiles induced by modified entropies as sources for traversable wormholes is investigated. Based on the Morris-Thorne reconstruction with a barotropic equation of state p_r = wρ, five models are analyzed: Barrow, Tsallis, Kaniadakis, logarithmic, and exponential. They yield qualitatively different density distributions: algebraic negative, localized, or capable of changing sign. Violation of the radial null energy condition at the throat ensures wormhole opening, while anisotropy of exoticity is controlled by the tangential and strong conditions. The force balance according to Tolman-Oppenheimer-Volkoff differs: in Barrow and Kaniadakis models, the gravitational and compensating contributions can change sign simultaneously; the other branches maintain a single sign structure with varying degrees of localization. Modified entropic profiles become effective sources for traversable wormholes, with the support mechanism depending on the choice of entropic deformation.
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.
