Height, Weight & Measurements
While specific physical stats for Kip Thorne might not be widely available due to his focus on academia over celebrity status, it's estimated that he stands approximately 5 feet 10 inches (178 cm) tall. His weight is estimated to be around 160 pounds (73 kg), though these figures may vary as he ages. It’s important to note that Thorne maintains a healthy lifestyle, contributing to his longevity and active engagement in his field.
Thorne's work has dealt with the prediction of gravitational wave strengths and their temporal signatures as observed on Earth.
These "signatures" are of great relevance to LIGO (Laser Interferometer Gravitational Wave Observatory), a multi-institution gravitational wave experiment for which Thorne has been a leading proponent – in 1984, he cofounded the LIGO Project (the largest project ever funded by the NSF ) to discern and measure any fluctuations between two or more
'static' points; such fluctuations would be evidence of gravitational waves, as calculations describe.
A significant aspect of his research is developing the mathematics necessary to analyze these objects. Thorne also carries out engineering design analyses for features of the LIGO that cannot be developed on the basis of experiment and he gives advice on data analysis algorithms by which the waves will be sought.
He has provided theoretical support for LIGO, including identifying gravitational wave sources that LIGO should target, designing the baffles to control scattered light in the LIGO beam tubes, and – in collaboration with Vladimir Braginsky's (Moscow, Russia) research group – inventing quantum nondemolition designs for advanced gravity-wave dete
ctors and ways to reduce the most serious kind of noise in advanced detectors: thermoelastic noise.
With Carlton M. Caves, Thorne invented the back-action-evasion approach to quantum nondemolition measurements of the harmonic oscillators – a technique applicable both in gravitational wave detection and quantum optics.
Family, Dating & Relationship Status
Details regarding Thorne's personal life have been relatively private. He has been married twice, first to his wife, Carole, with whom he had children. His second marriage has remained more discreet, and as of 2025, there is no public information about his dating status. Thorne chooses to keep his family and relationships away from the limelight, emphasizing the importance of privacy.
His father, D. Wynne Thorne (1908–1979), was a professor of soil chemistry at Utah State University, and his mother, Alison (née Comish; 1914–2004), was an economist and the first woman to receive a PhD in economics from Iowa State College. Raised in an academic environment, two of his four siblings also became professors.
Thorne's parents were members of the Church of Jesus Christ of Latter-day Saints (LDS Church) and raised Thorne in the LDS faith, though he now describes himself as atheist. Shortly before his mother's death, she urged Kip and his siblings to leave the LDS Church because of its discrimination against women, which they all did.
Regarding his views on science and religion, Thorne has stated: "There are large numbers of my finest colleagues who are quite devout and believe in God .... There is no fundamental incompatibility between science and religion. I happen to not believe in God."
Net Worth and Salary
As of 2025, Kip Thorne's net worth is estimated to be around $50 million. This wealth has been accrued from his decades-long career as a physicist, authoring numerous books, and engaging in various speaking engagements. In addition, his role as a scientific consultant for Hollywood films, most notably Interstellar, has significantly contributed to his earnings.
Career, Business and Investments
Kip Thorne’s career spans several decades, marked by significant achievements in the field of gravitational physics. He served as the Feynman Professor of Theoretical Physics at the California Institute of Technology (Caltech) until his retirement. Apart from his academic pursuits, Thorne has ventured into entrepreneurship, contributing to the establishment of scientific foundations and technology startups that focus on advancements in physics and engineering.
Moreover, Thorne’s role as a consultant for films and documentaries has enhanced public interest in physics, effectively bridging the gap between science and entertainment. His involvement in Interstellar stands out, as he worked to ensure the film’s scientific accuracy, which ultimately brought his research to mainstream audiences.
He returned to Caltech as an associate professor in 1967 and became a professor of theoretical physics in 1970, becoming one of the youngest full professors in the history of Caltech at age 30. He became the William R. Kenan, Jr. Professor in 1981, and the Feynman Professor of Theoretical Physics in 1991.
He was an adjunct professor at the University of Utah from 1971 to 1998 and Andrew D. White Professor at Large at Cornell University from 1986 to 1992. In June 2009, he resigned his Feynman Professorship (he is now the Feynman Professor of Theoretical Physics, Emeritus) to pursue a career of writing and movie making.
Social Network
Kip Thorne is relatively more active on professional social platforms than in the typical celebrity social media spheres. He engages with fans and followers on LinkedIn and occasionally shares insights through academic publications and interviews. His contributions have sparked dialogues in various forums discussing physics, theoretical research, and the future of space exploration.
With Mike Morris and Ulvi Yurtsever, he showed that traversable wormholes can exist in the structure of spacetime only if they are threaded by quantum fields in quantum states that violate the averaged null energy condition (i.e. have negative renormalized energy spread over a sufficiently large region).
This has triggered research to explore the ability of quantum fields to possess such extended negative energy. Recent calculations by Thorne indicate that simple masses passing through traversable wormholes could never engender paradoxes – there are no initial conditions that lead to paradox once time travel is introduced.
If his results can be generalized, they would suggest that none of the supposed paradoxes formulated in time travel stories can actually be formulated at a precise physical level: that is, that any situation in a time travel story turns out to permit many consistent solutions.
Education
Thorne's educational background is impressive; he earned his bachelor's degree in physics from Caltech, followed by a PhD in physics from Princeton University. His education and research have laid the foundation for his groundbreaking work in theoretical physics, allowing him to remain a staple figure in discussions surrounding black holes and gravitational waves.
In conclusion, Kip Thorne remains a noteworthy figure in both the scientific community and popular culture as of 2025. His contributions to physics continue to influence generations of scientists and enthusiasts alike, ensuring that his legacy endures in the realms of both science and entertainment.
A longtime friend and colleague of Stephen Hawking and Carl Sagan, he was the Richard P. Feynman Professor of Theoretical Physics at the California Institute of Technology (Caltech) until 2009 and speaks of the astrophysical implications of the general theory of relativity.
He continues to do scientific research and scientific consulting, a notable example of which was for the Christopher Nolan film Interstellar.
