Escape Velocity

Critical escape velocity of black holes from branes

In recent work we have shown that a black hole stacked on a brane escapes once it acquires a recoil velocity. This result was obtained in the probe-brane approximation, i.e., when the tension of the brane is negligibly small. Therefore, it is not clear whether the effect of the brane tension may prevent the black hole from escaping for small recoil velocities. The question is whether a critical...

A Relativistic Escape Velocity Maximum of Light Speed

There are parallels between the time distortion equations of General and Special Relativity. The time distortion in Special Relativity limits the “Real” velocity of a particle to the speed of light |c| by slowing the velocity of bosons/energy and increasing the mass of fermion||lepton (or matter) particles. In General Relativity, the gravitational slowdown of bosons/gravitons limits the escape ...

Simulation and perturbation analysis of escape oscillator

The dynamical behaviour of the forced escape oscillator, which depends on the parameter values we considered, have been studied numerically using the techniques of phase portraits and Poincar'{e} sections. Also, we employed perturbation methods such as Lindstedt's method to obtain the frequency-amplitude relation of escape oscillator.

Achieving Escape Velocity: Neighborhood and School Interventions to Reduce Persistent Inequality

Nearly 50 years after the Civil Rights Act of 1964, racial inequality in America remains a persistent empirical regularity. Despite much progress in the 1960s and 1970s, large adverse black-white gaps persist in earnings, employment, family income, health, life expectancy, incarceration, teen pregnancy, educational attainment, and academic achievement. Hispanic-white gaps in economic and educat...
