This fine channel always makes me smile! The HARDEST substance in the Universe is "Diamonds". I guess we will just have to wonder as it would not be Practical to DESTROY (or try to) a 100 carat Diamond?!?
I thought metals turned to liquid under enough force? My university had a 100 ton press and it would turn certain metals to liquid. Very dangerous but we did have a bulletproof viewing window.
@Remigrator metals are the solid materials which are typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g., iron, gold, silver and aluminium, and alloys such as steel).
@crushmasterchannel Ok, I understand that you don't understand. Sorry. I wrote in the comment that your older videos were better where there was an indicator of the pressure height, i.e. how strong the pressure must be to compress individual materials.
