4 unusual facts about Kip Thorne


Hoop Conjecture

Thorne, Kip, Black Holes and Time Warps: Einstein's Outrageous Legacy, W. W. Norton & Company; Reprint edition, January 1, 1995.

The Hoop Conjecture, proposed by Kip Thorne in 1972, states that an imploding object forms a black hole when, and only when, a circular hoop with a specific critical circumference could be placed around the object and rotated.

Inhomogeneous electromagnetic wave equation

Temporal paradox

Kip Thorne, however, said that none of the supposed paradoxes formulated in time travel stories can actually be formulated at a precise physical level: that is, any situation in a time travel story turns out to permit many consistent solutions.


Membrane paradigm

This approach to the theory of black holes was created by Kip S. Thorne, R. H. Price and D. A. Macdonald.

Wormhole

The debate on this matter is described by Kip S. Thorne in the book Black Holes and Time Warps, and a more technical discussion can be found in The quantum physics of chronology protection by Matt Visser.
