Are black holes springlike?
Stockholm University, Nordic Institute for Theoretical Physics (Nordita).
2015 (English)In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 91, no 4, 044031Article in journal (Refereed) Published
Abstract [en]

A (3 + 1)-dimensional asymptotically flat Kerr black hole angular speed Omega(+) can be used to define an effective spring constant, k = m Omega(2)(+). Its maximum value is the Schwarzschild surface gravity, k = kappa, which rapidly weakens as the black hole spins down and the temperature increases. The Hawking temperature is expressed in terms of the spring constant: 2 pi T = kappa - k. Hooke's law, in the extremal limit, provides the force F = 1/4, which is consistent with the conjecture of maximum force in general relativity.
