random thoughts on the discovery that black hole outflows contain rubies and sapphires
Corundum grains are always nice, even a micron at a time.

Interesting…intergalactic gemology? I suppose we can take the proposed output of rubies and sapphires and convert it to a monetary equivalent. Data mining, indeed.
Once upon a time, the rainbow’s end
Is where a leprechaun would hide his gold
Then Newton showed us how a glass would bend
A beam of light–a rainbow we behold!
This bending light is what allows, today,
A view of distant galaxies and more
The start of time itself is on display
And lifetimes’ worth of treasures to explore.
These treasures, it now seems, include real jewels
When quasar jets spit rubies and sapphires;
From Newton’s prism, oh what wondrous tools
Expose a treasure passing all desires
The rainbow’s gold’s forgotten; this is real:
A myth discarded, treasures may reveal!
