Struggling to get my head around this question.
Two events have spacetime coordinates (x, y, z, t) of (100 m, 0 m, 0 m, 2 μs) and (−900 m, 0 m, 0 m, 5 μs). Is it possible for both events to be measurements of the same particle? Give an explanation for your answer.

Work out how fast the particle would have to travel to get from one coordinate to the other.
Compare the speed that you have found with the speed of light.

Thank you! I was making it far too complicated than it needed to be.
