Physics · Space and Gravitational Waves
Consider the following statements regarding the Laser Interferometer Lunar Antenna (LILA): Statement I: LILA is a proposed next-generation gravitational-wave detector on the Moon, designed to detect mid-frequency gravitational waves (0.1–10 Hz), which cannot be observed by existing Earth-based or planned space missions. Statement II: The Moon provides an ideal environment for LILA because it lacks an atmosphere, has very low seismic noise, and is free from oceans and weather, thereby avoiding 'Newtonian noise.' Which one of the following is correct?
- 1Statement I is incorrect, but Statement II is correct.
- 2Statement I is correct, but Statement II is incorrect.
- 3Both Statement I and Statement II are correct, but Statement II is not the correct explanation for Statement I.
