Simulated: Alcubierre
by Unionegation
Simulated: Alcubierre is a NeoForge addon that adds an Antigravity Drive and a warp system for contraptions built with Create and Sable.
What it does
The Antigravity Drive hooks into the kinetic network and cancels out gravity, so a contraption can float in place and stay powered for long periods. Crafting one takes a Glimmering Bottle, which players obtain by filling an empty bottle in the End once the height drops under the -40 level.
The Alcubierre Controller works as a captain's seat. A player enters coordinates and a dimension, and the whole ship is warped there within a few seconds. A fire panel connects to redstone, so the warp can be triggered by circuits.
The addon depends on Create Aeronautics, Dimensional Sable and Sable, and every one of them must be installed. The release line bundles its own build of Dimensional Sable, since the upstream Sable 2.0.0 and later releases had not received an update for the addon. The mod is released under the MIT License but is not open source. It runs on client and server and is published for NeoForge in one game version, 1.21.1, with the latest file 1.2.6 dated 2026-06-23.

How it compares
Create Propulsion: Simulated is a NeoForge addon for the same 1.21.1 build, running on client and server and released under the MIT License. Simulated Addition is also NeoForge for 1.21.1 on client and server, and it is open source under the MIT License, so it adds to the same stack without the warp controller. Create: Droneworks Simulated is NeoForge for 1.21.1 on client and server, but it is not open source and is licensed as All rights reserved.
