Suppose that there is a black hole with such a mass (e.g. one thousand ton), so that it would evaporate (at rest, and no inflow of material or radiation) in ~80 seconds. If it is somehow accelerated up to (or the conditions under which it appears forces it to move at) 99.9% of light-speed, so that the Lorentz factor is ~22.37, would the black hole evaporate the same time (80 sec), or multiplied by Lorentz factor (~1790 sec) (for someone who is not moving)?
In other words, would the ultrarelativistic speed of the micro-black hole make its decay time longer than usual (for an observer who is at rest)? Or the Hawking radiation time is independent on the speed of the object?
