Like Galaxies Colliding - Release Coming April 26, 2019!
Far away from the city lights, on a cloudless night, it’s amazing what the star filled sky looks like and the passion it inspires. What can astrophysics teach us about love?
We are born out of nothingness and return to nothingness, moving in our time on this earth through both random and somewhat predictable interactions with strangers, families, friends and lovers. At times we are drawn inexplicably towards someone – almost by accident. In other cases our trajectories follow well foreseen paths, rising and falling through the milestones of coupling and decoupling, love and loss.
So too do the galaxies, stars and planets. Black holes have an innermost stable circular orbit. If you get too close, you inevitably plunge in. When two black holes merge, they become one forever. Galaxies do indeed collide. It takes millions of years, but that’s fast compared to the age of the universe. And in our own lifetimes, we collide, and these moments are fleeting but they redefine us forever.
When galaxies collide they can sometimes strip off each other’s gas and dark matter. The galaxies have a profound effect on each other. Courtesy of NASA, ESA.
