None of us are going to be around for the exploration of the entire universe, if it even happens with our species. There will always that "what if" floating around in the back of our heads. Creativity and imagination can gives us a little insight though. This thread is for developing your planet, super cluster, star, life forms, ecosystem, or anything you can wrap your mind around. Maybe a living planet that's composed of gas and later implodes causing particles to shoot out, creating life wherever they land. A species that lives on a planet that is inhospitable for 99 years / 100. It merges with it's surroundings and only pries itself lose that one year to repopulate. Hopefully this turns out interesting. It's a VERY broad subject with a virtually infinite amount of possibilities. Yes, I also know that humans have defined the way in which life needs to form... but we're not always right, are we? In the next hundred years we could find artificial ways to create life that completely debunk our current thinking. Never say never.
