Is it possible that objects like Borisov, asteroids, comets, even free floating planets permeate the vast regions of interstellar space. So objects like Borisov and Oumuamua are like nomads of the Galaxy having chance encounters with other Solar systems. If this is the case wouldn’t it be difficult to pin down the home star of these objects. Would more of them have a tendency to enter the Solar system from the direction of the Solar apex, the 19.5Km/sec motion of the Sun through space.
