Query: Do massive compact objects without event horizon exist in infinite
  derivative gravity?   Einstein's General theory of relativity is plagued by cosmological and
blackhole type singularities Recently, it has been shown that infinite
derivative, ghost free, gravity can yield non-singular cosmological and
mini-blackhole solutions. In particular, the theory possesses a {\it mass-gap}
determined by the scale of new physics. We will use this property to argue that
it is possible to form a non-singular super-massive compact objects without
having any event horizon in this class of theories.
