On the Stability of Slowly Rotating Kerr Black Holes

 By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation

A black hole is a solution to Einstein’s general relativistic field equations. Based on the property of angular momentum, black holes can be categorized into two types: non-rotating and rotating. The former is described by the Schwarzschild solution and the latter by the Kerr solution, originally named after its discoverers.

Perhaps all physical systems tend to move towards equilibrium irrespective of their initial conditions and similar is the case with black holes. A long-standing problem in black hole physics concerns the stability of these great astrophysical voids. The idea is to regain the original state of the black hole after the effect of an externally applied perturbation has faded away. This proves that the black hole is indeed stable. The case otherwise is an instability and would be quite a task in that it would compel us to modify Einstein’s theory.

Addressing this unsolved...

Rotating Black Holes May Serve as Portals for Interstellar Travel

  

By Dr. Inés Urdaneta / Physicist at Resonance Science Foundation

 

By means of numerical simulations and computational calculations, a team from the University of Massachusetts Dartmouth and Georgia Gwinnett College observed that rotating black holes can be traversable. The results were published in Phys. Rev. D, and the calculations were made by Caroline Mallary, student of the research team's director, Gaurav Khanna. 

Mallary wanted to test whether Cooper (played by Matthew McConaughey) in Christopher Nolan's movie Interstellar, could survive the plummet into Gargantua - a fictional, rotating, supermassive black hole about 100 million times the mass of our sun. The physical properties of this black hole were taken from the book written by Nobel laureate Kip Thorne, on which the film was based. 

These mysterious creatures called black holes, are regions in space where there is an enormous accumulation of energy/matter, concentrated in such a...
