and theoretically it can go up to 7 valence electrons bonding
also the more bonds an molecule has, the stronger it is and there are some molecules with 5+ bonds between two atoms
let's just say the rules is to be semi-realistic, so if it's theoretically possible than it can exist here
kyle the creator: according to some theories:1. black dwarfs and iron stars are indistructible, 2. it is possible if your not matter, 3. yet againdark energy can survive a kilonava(but this is all according to theories)
Fix your overpowered material please.
And no thing is indestructible
No material on the UNIVERSE btw too can survive against a kilonova
It is impossible to survive Antimatter since it converts ATOMS INTO LIGHT all materials should and will be equal to strength with ANTIMATTER
