Sampling again

This was actually the first sample towards an idea for Breakthrough - it's based on that card (David Austin, The Stars above the Sea) and on the celestial drawings/prints by Vija Celmins
I wanted the light to break through the dark areas, like a night sky - maybe with the odd constellation - and ended up looking in an astronomy book and finding a page about the search for the invisible, undetectable stuff called dark matter, how when scientists find it - or are sure that it doesn't exist, or know how much of it there is, one of those options (it's all a bit mind-boggling!) - then they'll be able to figure out how long the universe will go on expanding. That would be a breakthrough, but how much "practical use" is that knowledge ...
