Why aren't optical or radio telescopes used in particle astronomy, which studies cosmic waves and gravity waves?
A) Cosmic and gravity waves are too dangerous to detect.
B) Particle astronomy can only be studied in deep space.
C) Cosmic and gravity waves are too large of particles for ground-based telescopes.
D) Optical and radio telescopes can only detect electromagnetic radiation.
E) Optical and radio telescopes are not technologically advanced enough to capture these particles.

Question

Quizplus · Accepted Answer

Optical and radio telescopes are designed to detect electromagnetic radiation, such as light and radio waves. Cosmic and gravity waves, on the other hand, are not forms of electromagnetic radiation but rather perturbations in the fabric of spacetime itself (in the case of gravitational waves) or high-energy particles (for cosmic rays), requiring different detection methods.
