We can predict how many galaxies there should be based on physics. Anyway, my point was more that if we assume the universe is infinitely large and roughly uniform in density that it should have *infinite* galaxies in every direction
And unless something drastic changes, the horizon of observability is closing in on us, such that eventually our galaxy will be all that is knowable to its citizens, if any survive that long. In other words, there may be 50,000 galaxies in that circle *today,* but over time, that number's going to be fewer and fewer (for all practical purposes).
