>>81787250 (OP)The thing is, life is better hosted on planets that aren't in globular clusters. These are very old areas usually over 10 billion years old, and certainly around the black holes at Center many galaxies. And they commonly have stars that are all within one light year of each other and many times pass each other at 0.15 light years. And let's take humans for example. If a star got that close to our solar system, it's statistically something like virtually 100% of all mammal males are going to get an erection that won't stop growing until the veins burst and shoot out until all the blood is pumped out and they die. And then there you go, there goes the end of many species. This type of mass extinction has happened on Earth in the past. It's a crap shoot on what species it will affect. It has something to do with the interference of particles coming from the two stars and hitting each other and then bouncing around and hitting earth. And if it is a binary system, that passes earth, that's it. Every single organism on Earth will have their outer reproductive organs burst, and their titties will explode, and all the shellfish have their insides ripped out of their asshole, it's a crazy event.
