This server mod will allow you to create a new world that will be just like space, if your out in the open you will start to die but it will be like drowning (But not if your wearing a Space Suit) and if your in a closed space it will be safe unless there's an open iron door or trap door, if your using wooden doors you will need to use two (not side by side) and both have to be closed. In the space world all players can fly but if your inside gravity is normal. hopefully I can make it so that you can build space ships.
