Black hole A moves at slow velocity, and there's an Einstein light clock hovering near the event horizon.(adsbygoogle = window.adsbygoogle || []).push({});

Black hole B moves at high velocity, and there's an Einstein light clock hovering near the event horizon.

The black holes are identical. And the light clocks are at the same altitude, and comoving with their black holes.

Do the light clocks run at different rates?

(I mean, velocity addition is more of the ballistic kind in this case, right? So the normal time dilation does not apply?)
