Mathematicians find symmetry breaking in higher-dimensional black hole ringing
Lisa Lock and Robert Egan report on new findings regarding gravitational waves from higher-dimensional black holes published in Physical Review D.
New study challenges existing gravity laws
Researchers at Khalifa University in Abu Dhabi investigated how black hole vibrations change when space has more than three dimensions. They found that string theory corrections alter the standard gravitational wave patterns produced by merging black holes. The team discovered two distinct types of waves that ring at exactly the same frequency.
String theory adds specific mathematical terms
The study incorporates a term known as the Gauss-Bonnet term into Einstein's equations to model low-energy string theories. This addition modifies the curvature of spacetime and changes the notes of the gravitational wave chord. The results appear in the journal Physical Review D.
