“…and other lesson’s I learned when I was a spiral galaxy” — Our ideas of what happens to galaxies when they crash into each other comes mostly from simulations. But what if those results aren’t as trustworthy as we think? By watching a galaxy merger in the highest detail we can, we see that collisions may not be as destructive as we thought, and you just might survive a head-long crash into another galaxy.
