Hi there. So it seems there are multiple reasons for why our galaxy will come to an end. A potential cause is that a black hole will engulf our sun. Let's say that in another galaxy a star is born. There is a chance that a nearby planet will have the potential for sustaining organisms. How exciting if this is the case. It seems that for this to happen the planet should be very similar to earth. It should have an atmosphere with gases carbon and oxygen and hydrogen. And probably most of the other gases on our periodic table. this probably means that the life forms that would develop would probably be similar to Earth's? Would any planet that would sustain organisms probably be very similar to earth? Is there a very unique set of conditions required to sustain organisms basically? is there a very unique cycle of evolution of organisms?
