In this paper, we will analyze a time dependent geometry in a massive theory of
gravity. This will be done by analyzing Vaidya spacetime in such a massive theory of gravity.
As gravitational collapse is a time dependent system, we will analyze it using the Vaidya
spacetime in massive gravity. The Vainshtein and dRGT mechanisms are used to obtain a
ghost free massive gravity, and construct such time dependent solutions. Singularities formed,
their nature and strength will be studied in detail. We will also study the thermodynamical
aspects of such a geometry by calculating the important thermodynamical quantities for such
a system, and analyzing the thermodynamical behavior of such quantities.
