Even if there isn't (though I expect at least a soft limit), the idea that we would see constant expansion is questionable at best. Already we see an increasing and global trend towards urbanization and a leveling off of population growth. In other words, already we are seeing evidence that we aren't going to expand into some galaxy-spanning empire and that's before we get our fill of space colonization trying to expand to fill the solar system. We look to our past behavior and assume that means we're going to put Dyson spheres around every star we can get our grubby little hands on as we continue having exponential population growth when really we get an entirely different picture if we extrapolate current trends foward. Maybe the thing we want as a social species is NOT to be as far away from each other as humanly possible. On the subject, it seems notable that pretty much ALL our fiction seems to view a war between Earth and a Mars colony as inevitable. Maybe our future is to bloody our own nose one last time and finally recognize how short-sighted our history of colonization always was. Far more likely, I think, is that we will stay around our own star as long as we can and move to another star (singular) only when our current one is reaching the end of its life. Of course, such modest and nomadic civilizations would be far harder to detect than galaxy-spanning empires, so it would make sense that we haven't detected them yet.
