Whats the strongest substance on earth?

Question

just wondering whats the strongest thing you can form into a weapon i know adamantium is not real but what about something like Kevlar or dragon armor is that the best

Answer 1

strong is not a clearly defined term.

Diamond is the hardest, but it is brittle.

Answer 2

That would probably have to be aggregated diamond nanorods, these things are HARD, three times harder than iron.

This material also has the advantage of being relatively light, it has less than half the density of Iron (3.54 g/cm^3 as compared with 7.874 g/cm^3 for Iron).

It does have the somewhat large disadvantage that it requires tremendous pressures in order to be made. Currently only small quantities can be manufactured at a time, and it's fairly expensive stuff. So unlikely you could get a sword made out of it any time soon.

Answer 3

Carbon nanotubes, but I'm not sure what kind of a weapon you could make with those...

Answer 4

No way its diamond. Search more on its hardness
