Timescale for trans-Planckian collisions in Kerr spacetime
Timescale for trans-Planckian collisions in Kerr spacetime
We make a critical comparison between ultra-highā€“energy particle collisions around an extremal Kerr black hole and that around an over-spinning Kerr singularity, mainly focusing on the issue of the timescale of collisions. We show that the time required for two massive particles with the proton mass or two massless particles ā€¦
