#2Well this is certainly bad news for anyone who invested $35k in a vantablack wristwatch: https://www.h-moser.com/en/collection/1801-1200-endeavour-pe...

#3It is stated to be an order of magnitude better across the broad spectrum than other broad absorbers.
I wonder if there are any narrow bands that it specifically excels at compared to existing materials, and how big the difference is.

There is a graph right at the top of the abstract that shows the reflectance of this new material compared to Vantablack across a number of wavelengths.

#6What are the hopeful uses for making ever more absorbing black materials?

In my opinion, if you could afford $35,000 for a Vantablack wrist watch, you can afford another $35,000 for this one too haha. I doubt many of those purchasers were on the bubble.

If we were to shine a light into vantablack in a dark room ~0.04% would be reflected but it would be enough make the object visible. So, it is possible to differentiate both paints in those conditions.

reducing stray photons in instruments, you only want those that go through your lens array, not those bouncing off the housing.
