Giant Dark Matter Particles?

How do you call something a particle if it’s gigantic? From a
Scientific American
story:

In 1996 Discover magazine ran an
April Fools’ story about giant particles called “bigons” that could be
responsible for all sorts of inexplicable phenomena. Now, in a case of life
imitating art, some physicists are proposing that the universe’s mysterious dark
matter consists of great big particles, light-years or more across. Amid the
jostling of these titanic particles, ordinary matter ekes out its existence like
shrews scurrying about the feet of the dinosaurs.

The story goes on to say that researchers at the
Center for Research and Advanced Study
in Mexico city and others have come to this conclusion based on the fact that astronomers
observe far fewer small galaxies than statistically are expected to exist. This might be because
of giant dark matter particles that resist compression.
