The title is completely false. Metals are used for their material properties more than just strength but homogeneous strength and stiffness (in all directions) and tolerance to a wide range of environmental conditions (thermal and moisture cycling) Not to mention ease of manufacturing. The material described in the article will never make it out of the lab.

>The title is completely false.

No idea why you claimed that. What is completely false is your claim, by the sound of it. Did the title claim anything about properties other than strength? No. I think you may have meant "The title is misleading (although literally true)" or something.

edit: Would downvoters care to explain why? Thanks.

And if you keep going, you'll eventually create a black hole.

Mini black hole, evaporating fast unless you feed it faster!

Annnnd... Now I'm reading about black holes, no-hair theorems, how zero mass particles behave around black holes. Goodbye productivity! :)

Define "stronger"

The article is pretty confused about what they mean by stronger, on the one hand they use language that suggests tensile strength but they then go on to illustrate some non-quantitative measure by talking about penetration by pellets and deformation in collision like situations.

Are there any interesting trivia figures for that?

Like how long would it take to evaporate a black hole with an event horizon the size of a basketball, golf ball, grain of sand, whatever?

Its adding wood pulp to ice to make the ice much much tougher. It was invented by the epitome boffin Geoffrey Pyke, who proposed they build an aircraft carrier of it! https://en.wikipedia.org/wiki/Project_Habakkuk
