Who made you the maker of the rules? (srsly tho, there are enough rules in TPT already)
Honestly, TPT isn't entirely realistic in itself, first of all, it's 2D, second, this is pretty acurate but all in all, those indestructible materials generally represent a function performed by legitimate objects in our feasible reality (VACU for example)
BHOL? But if I made realistic galaxy? ;) And turn on water eq.
no insulation? that makes creating almost any form of a "realistic" power generator almost impossible without using the other banned items
Oh yeah and consider adding FILT. It's mostly indestructable. (exception for electronics)
Why isn't VACU legal? Vacuums do exist, ya know...
BCLN should be legal, but not CLNE.
Also, must use ambient heat [ON] and newtonian gravity [ON].
in a realistic save you can only use hydrogen and hydrogen fusion or it's not realistic oh and the fundamental particles: phot neut elec grvt
