This mod aims to add somewhat scientifically accurate time travel and (in a later update) the option to create time paradoxes. Using a conduit, a lava bucket, a nether star, a heart of the sea, and other materials, you can create a tier 1 time machine that can only go into the future. In the future you can find Tachyonic fluid in a laboratory that you can use to make a tier 2 time machine or use the built-in time machine there. Now you can go into the past! DISCLAIMER: There is a Bootstrap paradox in this mod. Google it... or Bing it idc. The paradox will be fixed in the release version of this mod.
