This is my adaption of several things from Christopher Nolan's recent Interstellar. I made the Endurance Spacecraft with full interior (see if you can find TARS and CASE), the water world from the movie, and I used a modified version of MCCM's Realistic Snowy Mountains terrain for the ice world and a modified version of Planet Minecraft's "To The Stars" contest starter map as the Wormhole.

You can teleport to the worlds from inside the cockpit of the ship. Just find Ranger one and pick a world!

I reccommend playing in Creative as the ship was designed with zero gravity in mind (although I've added some support for earthly users). At some point, I might use command blocks to make the whole thing spin, but for now this will have to do.

There is a daylight detector keeping it night, for a spacey effect. If you want to change that, it is located behind the ship, on the edge of the super flat world.

Here's the base I used for the ice world:

And here's the thing I modified to make the wormhole:

Check out my other stuff, don't steal, and if you're still reading this, say "Do Not Go Gentle" in the comments. Thanks!
