Physicists have detected hot dark matter particles in terrestrial laboratories, but it is muchharder to observe than cold dark matter.

Question

Quizplus · Accepted Answer

Hot dark matter particles are much harder to detect in terrestrial laboratories compared to cold dark matter particles. Hot dark matter particles are highly energetic and move at speeds close to the speed of light, making them difficult to observe in terrestrial laboratories. In contrast, cold dark matter particles move at slower speeds, which makes them easier to detect through gravitational effects.
