Elusive

- The humans are looking for super-diamonds again!
- Yes, I know, they should restore the wetlands instead...

New research suggest that a material 30% tougher than diamond can in fact exist...but probably only in the interior of exoplanets. However, once formed, it could remain stable even in our atmosphere. So now we know what to ask exoplanetary aliens to bring as gifts to our leaders, should said aliens ever visit our tried and tested "endoplanet"...   

Elusive form of carbon tougher than diamond, forever out of reach?
