基普·索恩
He earned a PhD in physics from Caltech under the supervision of Kip Thorne. Among his nine published peer-reviewed papers, his most notable theoretical contribution is his pioneering analysis of time travel through traversable wormholes, coauthored in 1987 with Kip Thorne, and Ulvi Yurtsever. Kip Thorne tells the story of this discovery in his 1995 book "Black Holes and Time Warps: Einstein's Outrageous Legacy".
