For more than a century, scientists have been fascinated by the jet that forms after a drop impacts a liquid. In this study, researchers tracked fluorescent particles in the fluid to understand the velocity and acceleration of flow inside the jet.

“Using nothing more than Newton’s laws of gravitation, we astronomers can confidently predict that several billion years from now, our home galaxy, the Milky Way, will merge with our neighboring galaxy Andromeda. Because the distances between the stars are so great compared to their sizes, few if any stars in either galaxy will actually collide.

Any life on the worlds of that far-off future should be safe, but they would be treated to an amazing, billion-year-long light show a dance of a half a trillion stars to music first heard on one little world by a man who had but one true friend.”
