Overview

This mod adds space travel and time travel to Minecraft, as well as 2 secret, extremely rare mobs. The name (and logo) is inspired by Cosmos: a Spacetime Odyssey, because it adds both space and time to Minecraft. Anyway, as for specifics (as specific as it can get anyway), it adds all the periods, eons, and eras of Earth's history (from the Hadean through the Quaternary, something literally no other public mod does, the most I've seen is Prehistoric Nature, and that adds the Cambrian through the Jurassic, as well as the Hadean through the Ediacaran which is grouped into "Precambrian"), all "interesting" objects in the Solar System (I use this term quite loosely, but it includes all planets and major dwarf planets, as well as all major moons excluding Tethys, Dione, Rhea, Ariel, Umbriel, Titania, and Oberon, but those are all planned for future updates; as well as Phobos and Deimos). It also adds several exoplanet systems, namely the TRAPPIST-1 system, the K2-18 system, the Copernicus (also called 55 Cancri A) system, the TrES-2 system, and the WASP-12 system. As stated before, there's also 2 secret mobs, but I won't elaborate further, seeing as they're secret, and I'll only state their existence. I also added fossils and "machines" that allow you to get to the dimension in survival in some way, analyzing fossils for space, and 3 tiers of telescopes for time. The time travel mechanic is accessable via a time machine, as that made the most sense to me, while the space mechanic is accessible by right clicking blocks with textures similar to the planets. I did this specifically because UniversIO does this same thing, but just with Earth, and apparently the Moon and the Sun, which isn't much of a universe.

Current dimensions (space and time)

⚠️ means that it spawns you in lava, either because that's what it actually is/was, or because it has no solid surface so you'd die anyway. It's because of this and an advancement which I will not elaborate on that Hardcore mode is not recommended at all, but you're you, so I won't stop you, but just be warned.

⁉️ means that the composition is unknown and the object doesn't have an actual picture or map beyond just a white dot (or none at all), so I made the block's appearance how I either think it might look or how I want it to look.

❓ means that the object doesn't have an actual picture or map beyond just a white dot (or none at all), but the composition is known, so I made the blocks based on simulations with the known composition and orbital parameters in either SpaceEngine or Universe Sandbox.

Future plans

The Kepler-186 system
The HD 189733 system
Animals, plants, and fungi from the modern day (they spawn in the overworld and quaternary because they aren't extinct)
Time travel to human history
Time travel to the future
The Tau Ceti system
More extinct life
A microscope
Life on planets and moons we think could have life but haven't confirmed yet (within reason, Mars would have that one "fossil" rock, Europa would have bacteria to go with the microscope, and K2-18 b would have fish)

Scrapped features and other stuff

Scrapped features

A rocket ship (The GUI was so complex that it crashed the game when it opened)

Other stuff

This was originally planned to be a modpack, and I tried making one for like a month, but the GUI for the space mod addon thing had too much stuff, the next month I tried making it in 1.12.2 instead of 1.20.1, but I couldn't get the entities to work, then the next month I took a break, then I was like "why don't I make a mod myself?" so I started on this one last week and I finished it today. I will probably still make the modpack, just with this one instead of the 40+ mods, and I'll put the FTB Quests mod, more for education than anything.
