Temporal Horizons (Time Travel & Time Paradoxes)

Temporal Horizons is a time-travel mod that lets you explore the same Minecraft world across several different eras. Terrain, oceans, vegetation, structures, entities, the sky, and many other environmental features change depending on the selected time period. Some changes made by the player can also propagate through time, creating a connected timeline between eras.

Added Items: Time Jumper Device Opens the era selection menu and allows you to travel through time.

Fast Return Device Quickly brings you back to the Present from any other era.

Temporal Instability Detector Allows you to see the exact value fo your current temporal instability.

Available Eras: Past 3 Billion Years Past 1 Billion Years Past 400 Thousand Years Past 10 Years (World as it is generated) Present (Overworld) Future 2 Thousand Years Future 400 Thousand Years Future 3 Billion Years Future 6 Billion Years

Each era presents a unique version of the world, ranging from ancient oceans and frozen landscapes to ruined civilizations and a planet transformed by the distant future.

Do not keep your render and simulation distance too high or it will be very slow to load era's dimensions (Recommended render distance: 12 chunks, simulation distance: 10 chunks). To avoid crashes while switching eras, it is recommended to return to the Present before traveling to another era. Do not travel too fast between eras when loading them for the first time, wait until all chunks within your render distance are fully loaded before changing era again.

Player-built structures created in Past 3 Billion Years, Past 1 Billion Years, and Past 400 Thousand Years are intentionally not preserved in later eras. This is a gameplay design choice, not a bug.
