Tidal Accelerations at a Wormhole Throat and the Radius a Human Traveller Requires
Year: 2026
Type: article
Abstract: A human traveller two metres tall crossing a wormhole throat experiences tidal accelerations that scale as the inverse square of the throat radius. Using the Morris-Thorne tidal relations with an order-unity curvature coefficient appropriate to the zero-tidal-force shape family, a throat of one hundred metres imposes about 5.00e+03 times Earth gravity across the traveller's body, which no traveller could survive. The radius at which the radial tide falls to one Earth gravity is 7.071e+03 metres, roughly seven kilometres, and at ten kilometres the tide is 0.50 of a gravity. The verdict is plain: human traversability is a kilometre-scale enterprise. Any throat small enough to build with planetary quantities of exotic matter is far too small to cross, and any throat large enough to cross demands exotic mass far beyond planetary scale. This study is computed from stated assumptions, not measured.
