Pilgrim Dark Energy
  In the present work, we reconsider the idea of holographic dark energy. One
of its key points is the formation of the black hole. And then, we propose the
so-called "pilgrim dark energy" based on the speculation that the repulsive
force contributed by the phantom-like dark energy ($w<-1$) is strong enough to
prevent the formation of the black hole. We also consider the cosmological
constraints on pilgrim dark energy by using the latest observational data. Of
course, one can instead regard pilgrim dark energy as a purely phenomenological
model without any physical motivation. We also briefly discuss this issue.
