Let's say there a moving system consisting of X-Ray photon source and

The whole system is moving with a high speed horizontally. When the
detector registers a photon it triggers a gun that kill a cat moving
along with the system. If the speed of the system is high enough
relative to the distance between the source and detector, the observer
will see X-Ray photons missing the detector, and cat being alive.
While for the observer moving along with the system, the photons will
always hit the detector, and the cat will be killed.
Is the poor guys alive or dead?
I have never seen this paradox anywhere in the literature. Have I
missed it?
No observer will see the x-rays missing the detecter. Look up
aberation.

To complicated it even more, what if we have the detector move in the
vertical direction away from the source or toward the source (in the
source's reference frame). It doesn't change the fact that in the
source's reference frame, the photon will always reach the detector.
But I am not so sure about any moving reference frame, even
considering aberration?
