Every planet in the universe has the potential for life, but only a few per solar system use the available resources and succeed. Life has a tendency to become more and more curious and expand, and eventually it meets the rest. Eventually, so will we. Our ships will take decades to build, but so will their ships. After millions of years of evolution, as on Earth, appearance matters most. It is the deciding factor that separates the alpha inhabitants from the fringe inhabitants. The winner gets to land on the most fertile planet and from there move on to the next star system.
When the small building blocks that are floating around in asteroids everywhere have evolved into large spaceships and cohesive star systems, the big task begins: the trek to another galaxy. Only the most powerful starships can take part in this journey. Oddly enough, the stupidest thing to do is to simply travel outward. One would sail into a perpetual wave of dark energy, and the distance would increase. The other way would make sure that you would never get back. The black hole could host a wormhole, but no one knows for sure where it leads. Most likely, we would end up in the singularity. However, there is a third way, which can be seen only with the third eye.
We can travel to any place in our minds without the speed of light being a factor. We can record our travels by writing about them, making movies or plays. Close your eyes and you will see everything you can see. Realise that you are where you need to be. And that the best spaceship there is is your own imagination.
