Question

Quizplus · Accepted Answer

Atoms and ions in interstellar space, even though sparse, can indeed become highly energetic particles when a spacecraft travels at near-light speed, effectively bombarding the spacecraft with what can be considered a form of cosmic rays. This can pose a significant hazard to both the spacecraft and its occupants due to the high relative velocities involved.
