This paper proposes that the primary driver of extra-planetary experimentation is not existential risk but precision. A planet's own physical properties — gravity, atmosphere, magnetic field, vibration, and scale — become the dominant source of experimental noise at a sufficient level of scientific ambition. This point is named the Planetary Interference Horizon. The paper documents the historical progression toward this horizon in astronomy, gravitational wave detection, particle physics, and zero-gravity physics. The planet is not in danger from the experiment. The experiment is limited by the planet.
