Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the volume. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333.... so yes, density decreases as volume increases.

The main theoretical characteristics of a WIMP are: 1  Interactions only through the weak nuclear force and gravity, or possibly other interactions with cross-sections no higher than the weak scale; 2  Large mass compared to standard particles (WIMPs with sub-GeV masses may be considered to be light dark matter).
