The Multiverse is HUGE!
I’ve been playing space games since around 1982. I grew up watching Star Wars and Star Trek. For the longest time, I’ve thought about the vastness of space.
There are billions of stars out there. There are billions of planets around them. Now, those billions of planets, there are billions upon billions of moons. By this logic, how many of them support life of some sort? It staggers the imagination.

Want to go another step deeper? The human eye can only perceive maybe 3% of what’s actually out there. Take any “regular” planet and add the onion layers of dimensional energy beyond human sight. Then include the notion of time and alternate timelines.
Whew! Now we’re pretty deep in this particular rabbit hole. And I’m only talking about ONE planet! What else is out there?
We humans haven’t even explored a vast amount of Earth. That’s the “normal” realm. Imagine the amount of those myriad onion layers of dimensions can be explored within the sphere of one planet.

Yes, build rockets and warp engines to go explore. Sure. Hyperspace is potentially one of those onion layers of energy I was talking about above. Traveling at speeds beyond mere human comprehension is one of the great mysteries we struggle to overcome in fiction and real life.
Once we get out there, and we discover a new planet, it’s going to have all those facets to potentially explore on top of whatever sentient three dimensional creatures we might encounter.
So the next time you’re writing about “strange new worlds, to seek out new life and new civilizations,” just remember that we’re talking about an infinite source of adventure and wonderment. Please also remember not everything in the Universe is determined to kill, probe, or eat humans.
Ha! I bet some of you thought I wasn’t going to bring this back around to fiction. I’ve seen so many RPG sourcebooks and charts try to simplify planet creation. I mean, yes you literally can roll dice all day and determine populations and weather patterns. I’m sure Traveler probably has an entire sourcebook dedicated to it.
But here’s the kicker- you don’t need all of that. Even in a completely random game or fictional environment, location is just another plot element. GMs- save yourself the headache and just describe it the way you want to fit it into the story. I mean, unless you really are worried about how many milliliters of rain fall on the opposite side of the planet from where your characters currently are. (Not trying to squash anyone’s fun here.)
Thanks for stopping by. I appreciate you! Take care. See ya soon.
