Abstract: I discuss recent development in investigation of physical consequences of exotic differential structures on manifolds. I show, following T. Asselmayer, that corrections to the curvature after the change of differential structure produce a source like term in the Einstein equations. Then I give examples of topologically trivial spaces on which exotic differential structures act as a source of gravitational force even in the absence of matter.
