For Sci-Fi Universes, space travel is almost always a must have. In order to travel to different planets within and outside of the solar system or even to other galaxies, you need some pretty impressive technology. You don't have to be a science wizard to create your space travel. All you need are the hows and whys, and be consistent. Here are some things to think about: What is the source of your space travel technology? Special fuels? Magic? Dark matter? How easily is this obtained? Is it rare or expensive? Who has access to space travel? Everyone? The government? A single planet? Specific alien races? Are there multiple methods of space travel? Ships? Wormholes? Teleportations? If you can think of anything to add in, please do!
