WIMPs stands for which phrase?

• A. Weakly Interacting Molecular Particles
• B. Weakly Interacting Massive Particles
• C. Weakly Inertial Massive Particles
• D. Weakly Integrated Massive Particles

Answer: (B)

WIMPs are named to describe particles that would interact only weakly with ordinary matter and have mass. The phrase “Weakly Interacting Massive Particles” captures two essential ideas: their interactions are extremely feeble (mostly via the weak nuclear force and gravity), and they are not massless, which makes them candidates for dark matter that can contribute gravitational effects in galaxies and the cosmos. The other options use terms (molecular, inertial, integrated) that don’t reflect the standard physics meaning or the particle nature of these candidates, so they don’t fit as the established description.
