What would our experience be like on earth if the milky way was colliding with another galaxy?

In the span of a human lifetime, you wouldn't even notice anything was happening. Over the long-term, the odds are very good that nothing at all would happen to our solar system as galaxies are almost entirely empty space, but there would be a small chance of a collision with other bodies or that the Earth or our solar system is ejected during the merger.
