Here are some objects you can use for your game to play around with:
Gigantica Z1 (a giant cold sun with the radius of 85000 Milkyways)
Carus Caleis ZD (a giant black hole with the radius of 85000 Milkyways)
PI-211 (a "neutron star" with the luminosity of 721 Billion suns) (roasts everything within 100 lightyears range)
Giganticus B (a giant star that has only 241 AU radius)
How to install (windows):
1. Go to your "documents" folder
2. Now open the "Universe Sandbox²" folder
3. Drag and drop the .ubox folder into the "bodies" folder
4. Have fun!
(the object should be located under "user objects" when you try to spawn an object)
