The river model of black holes (Andrew J. S. Hamilton et al.) describes this spacetime as space beyond the event horizon falling faster that the speed of light: http://jila.colorado.edu/~ajsh/insidebh/waterfall.html.

One partner of a pair of formerly virtual particles. That which remains when Hawking radiation is emitted. https://en.wikipedia.org/wiki/Negative_energy#Quantum_field_effects Is yours a proper sender address? -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail. |
