I'm saying that there is no sheet of graphene that exists unsupported.

I'm saying that any smooth surface on a lump of coal probably has small sections of it that are graphene. The thing is that if you touched those smooth sections, you'd break the bonds that were holding those atoms in place.

In reality, a sheet of graphene is held by something. If you could somehow magically create a "large sheet of graphene" and you didn't hold each molecule in a sheet, then it would just crinkle up into ordinary coal.

My point is that NO, graphene can't support anything, not even itself. However, if it's held in place by some substrate, then it could be strong. I don't know. My point is that by itself it is weak, but as a carbon composite material, I don't know.

No one anywhere in the world has produced a sheet of graphene anywhere near the size of a cat, so it's probably just someone trying to phenomenalize something for attention.

Also, a lot of people say a lot of things about cats.
