Microlensing has become a powerful method to detect extrasolar planets beyond the snowline and free-floating planets. In this talk, I will first discuss the basic concepts of gravitational microlensing, then review some of the recent progress and finally discuss the future outlook.

I will present some recent findings regarding modified gravity's effects on non-relativistic stars and substellar objects. I will demonstrate how some parts of stellar modelling, star's evolution, and cooling processes in substellar objects are affected by alternative theories of gravity. Moreover, I will briefly discuss a few possibilities to test theories of gravity.
