We compute the gravitational wave energy E_(rad) radiated in head-on collisions of equal-mass, nonspinning black holes in up to (D=8)-dimensional asymptotically flat spacetimes for boost velocities v up to about 90% of the speed of light. We identify two main regimes: weak radiation at velocities up to about 40% of the speed of light, and exponential growth of E_(rad) with v at larger velocities. Extrapolation to the speed of light predicts a limit of 12.9% (10.1, 7.7, 5.5, 4.5)% of the total…

Does Charge Matter in High-Energy Collisions of Black Holes?
We perform numerical-relativity simulations of high-energy head-on collisions of charged black holes with the same charge-to-mass ratio λ. We find that electromagnetic interactions have subdominant
Malaise and remedy of binary boson-star initial data
Through numerical simulations of boson-star head-on collisions, we explore the quality of binary initial data obtained from the superposition of single-star spacetimes. Our results demonstrate that
Evidence for violations of Weak Cosmic Censorship in black hole collisions in higher dimensions
Abstract We study collisions of boosted rotating black holes in D = 6 and 7 spacetime dimensions with a non-zero impact parameter. We find that there exists an open set of initial conditions such
Space–time singularities and cosmic censorship conjecture: A Review with some thoughts
The singularity theorems of Hawking and Penrose tell us that singularities are common place in general relativity. Singularities not only occur at the beginning of the Universe at the Big Bang, but
Cosmic censorship and the evolution of d -dimensional charged evaporating black holes
The cosmic censorship conjecture essentially states that naked singularities should not form from generic initial conditions. Since black hole parameters can change their values under Hawking

It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)
