Suppose there are 2 huge planets far away from all other bodies.They exert gravitational force on each other and thus start moving towards each other with acceleration. Now they are very far away from each other so constantly accelerating there speed reaches near that of light, there mass increases so does their gravitational attraction and hence speed.Now can their speed ever cross that of light?

Practically the movement is not possible.If they are so far apart,then those planets would be attracted by some other closer object.
