I was attempting explain to a co-worker my novice understanding of relativity, I'm was explaining how speed/time/events/etc is relative. My question was could this also lead to a paradoxical/multi-universal(excluding string theory) when two events separated by space are linked?
I thought about a scenario with which there are two bombs, only 1 bomb could explode (through whatever hypothetical means). A timer is set on both bombs for 10 seconds and 1 person picks up each bomb. Person A stands still, person B travels close to the speed of light close to the speed of light (person A and B can observe each other). Person A, observing person B sees that person B's countdown is going slower (since person B is traveling faster), thus persons A's observes his own bomb going off first which leads to person B's bomb being disengaged (Person B lives).
Person B however, is observing everything else(including person A) moving close to the speed of light in a circle around him (since speed is relative to the observer), thus he observes person A's timer going slower and thus his own explodes first and disengages person A's bomb (Person A lives).
From each perspective, the observer dies and the other lives, which seems to create two conflicting realities, so who actually lives and dies. I feel as though I am misunderstanding something here or am I correct?
