Well the scan said something about destroying an antenna to "undo these worlds", and then "this endless multiverse" (which I'm assuming is what was meant by "these worlds") but to me that suggests destroying one multiverse, but not directly, rather by destroying an antenna that was keeping them stable or something.
Well I looked at it, but it didn't really clarify anything. It mentioned a multiverse of 52 universes, of which 44 had been destroyed. Also the Dark Multiverse, which, IIRC, also has 52.
I think that I read the wrong one, then. I'll look at those when I have the time (although in the one I did read, it seems that they did my boy Alec Holland dirty...).
That's why I used quotation marks. Coal is just a generic name for certain kinds of rocks and minerals that have high carbon content, whereas graphite is a well-defined crystalline allotrope of pure carbon.
It is possible for the coalification process to yield almost pure graphite, though. It is quite rare but, for example, in China there are graphite mines.
I understand what coal and graphite are. And they're two very different things.
The only thing they have in common is that they're both black band have carbon in them. But it is impossible to create coal from pure diamond, just by the addition of energy - even disregarding the fancy words toy put in your original post.
You need to add water, add sulphur, add nitrogen etc. They're two completely different materials.
But they are not very different things. As I said, the term coal does not refer to any specific material but to a range of carbon-rich materials at different stages of coalification. It is possible under certain conditions for this process to eventually yield mineral graphite.
Thus, depending on one's definition (there's not a universally agreed-upon one for coal), graphite mineral can indeed be said to be a type of coal. And various amorphous/glassy derivatives of it can be called coal, too. For example, wikipedia lists graphite as a type of coal: https://en.wikipedia.org/wiki/Coal#Types
Superman is therefore certainly allowed to refer to the polyaromatic carbon material he produced as coal. Although, personally, I would place the term in quotation marks (as I did earlier).
Vector is strong enough to rip holes in spacetime and repel the mass of a planet. Pushing through his blasts is a very good strength feat. But it's not universe level.
The crossroads directly connects to infinite dimensions, so that's why Hulk and Ironclad's clash there reached all of them. That doesn't make either one of them infinitely strong. (FYI I don't buy the 'lifting an infinite page book' feat being proof of infinite strength either, so I'm not being biased here).
