Question

Quizplus · Accepted Answer

All of the options listed are considered candidates for galactic dark matter. Brown dwarfs, faint red stars, and Jupiter-size objects are examples of MACHOs (Massive Compact Halo Objects), which are massive objects that might contribute to dark matter through their gravitational effects but do not emit or reflect enough light to be observed directly. WIMPs (Weakly Interacting Massive Particles) represent a different category of dark matter candidates, hypothesized particles that interact through gravity and possibly the weak nuclear force, but not electromagnetically, making them effectively invisible and detectable only through their gravitational effects.
