The two galaxies are presently a Vegas Golden Knights Stanley Cup Champions Poster shirt two million light years, give or take, from each other. They are expected to collide, and eventually merge, several billion years from now. Don’t worry, it won’t affect us much. For starters, we won’t be around. The Earth will be a dead world by then, with the Sun near the end of its life as a main sequence star. But even if that weren’t the case, stars are so small compared to the distances between them, no individual solar systems are expected to collide as this merger takes place. It cannot be excluded with certainty of course, but it is unlikely that any star during the merger event will come much closer to the Sun than our nearest stellar neighbors are at present, i.e., never approaching our Sun closer than a couple of light years.

These processes take a Offcial volshop Tennessee baseball omavols cartoon shirt years or so and once the Earth becomes potentially capable of supporting life, we actually see the earliest signs of life during that period. It could have just as easily taken another billion years to hit upon the first self-replicating molecule. We don’t know the exact details of how life got started but we do actually know lot about the kinds of processes it would have required. The key event would have been the first self-replicating molecule – which probably was not life as we know it, but an RNA precursor. The next key event would have been the conversion from RNA to DNA-based life. Forming the right kinds of molecules in the right concentrations at the right Ph levels isn’t something a new world is likely to hit upon immediately, and indeed, it seems like it took at least a few hundred million years before we see the first artifacts of life on Earth.
