Small Dark Matter Particle Size
Illustration
This illustration and its companion are intended to
demonstrate the implications of various sizes of dark
matter particles. The analogy compares dark matter
particles to the people gathered in Times Square. In
this image, the people are relatively small and,
therefore, can congregate relatively close to one
another. In the situation of dark matter, this would
mean that astronomers would expect that dark matter
would be confined to relatively small areas if the
particles were smallish.

Larger Dark Matter Particle Size
Illustration
In this view, the particles (people) are bigger than
the other illustration. It is shown that as the size of
the people grows, they are forced to scatter farther
out into Times Square using this analogy. If this were
the case in the universe, then astronomers would expect
that dark matter would be spread out over a larger area
than if the particles were smaller in size.
