For most of human history, the night sky has appeared to us as if it's fixed in time. The recent revolution in time-domain astronomy and precision measurements now reveals a dynamic universe and offers us a view of the lives of galaxies on human timescales. Our team has been carrying out precision measurements of the accelerations of stars that live within our Galaxy. These acceleration measurements now show a very different picture of the Milky Way - we see that the dark matter zig zags around the Galactic disk, and that the Galaxy is bottom heavy, wobbling much like a toddler. I will talk about these recent discoveries and end by talking about the future of acceleration measurements in the next decade in probing the universe at large.
