The collision between Andromeda and the Milky Way. Based on what we read from many science writers, we would think that doom is looming any minute now. Is that really mainline thought, among the scientific community, or just sensationalism? My view is that it is just sensationalism that sells in the shot term but damages the credibility of science as a whole in the longer term. After all, this event is 4-5 billion years away, and no one now alive, or even our very remote descendants, will feel any impact from it. At the worst, the back holes from the two galaxies will merge, and with a huge burst of energy, do a lot of damage a few million light years away. Stars very far apart, most will pass on by each other, and the worst threat they pose is causing a few stray comets to impact a few planets. Four or five billions years from now. Gimme a break Jake, but I fail to see how this is a problem that can't be dealt with then, if anyone is alive to want to deal with it.
