And the wikipedia, if you trust wikipedia:
https://en.wikipedia.org/wiki/Graphene

I can't believe I just now discovered it.

If you want a short description on it:

Graphene was discovered in 2004 by taking graphite, and getting a single layer of it. The atoms are arranged in a honeycomb pattern. This material is apparently the strongest, even stronger than diamond. It's extremely conductive, and extremely flexible. This means more efficiency with current technology, such as having the possibility to create smaller computer chips, improve battery life, and make solar power more efficient. As well, the only material capable of passing through it is water, so it acts as a filter. It is known to be the greatest water filter in the world.

~ This is just the information that I have heard about it, if you would like, it would be cool to hear the opinions of everyone else. I'm still continuing research with it. :)

Just a small conceptual correction: diamond is not strong, it is hard.  If you really had a diamond sword then it would shatter on impact with pretty much anything solid. :)

Mohs scale, that's correct. I keep acting as if they were synonyms. :)

I wonder why it isn't more widely publicised.

I don't know Paul, my diamond sword does a pretty efficient job chopping up endermen.  ;D

It is pretty widely publicized, I think.  I heard of graphene some time ago.  There was even a video somewhere showing how to make it.

Heheh... would this be in the same game that lest you carry more stone than a container ship could carry? :)
