I mean, matter is mostly empty space…
Only if you really distort the definitions. The "empty space" you are thinking about is the matter. You can't just put other stuff there. There's a similar wrong meme about how you never really "touch" anything.
Ok, what is the exact moment you touch something? How close do the atoms need to be?

I would suspect it is essentially invisible to the naked eye. It likely only exists in extremely specific conditions, not just like a sheet. I’m guessing it’s somewhat similar to a microscopic layer around a material that we never notice.
Thin gold layers are green, this looks red if you look at the beaker. There are spectral data available in the original publication https://www.nature.com/articles/s44160-024-00518-4
Oversimplified TLDR: They put rolled gold into a Prussian Red solution, waited a couple of months and then rinsed it in Palmolive solution? It is possible they did not obtain the Prussian Red in the good old way of cooking blood and bones with potash but ordered it from the Internet: https://www.morphisto.de/en/shop/detail/d/KIT%3A_Ätzmittel_n... On a more serious note, it is surprisingly easy to create mono- molecul…
Why goldene and not chrysene?
Interestingly, it is a 2-dimensional (planar) compound itself.

Graphite is a pretty common word, and it's easy to make the connection between that and what graphene is. Same goes for gold and goldene. Not so much for chrysos and chrysene.
The point of systematic naming is predictability through consistency, not appealing to the lowest common denominator. But Sweden isn’t exactly known for its stellar educational system, so it doesn’t surprise me that their chemists don’t learn Greek.
