Because They’re Big
Yellowstone caldera today, Hayden Valley
Where river Drac joins the Isère,
A synchrotron ring is there,
A stadium sized machine
That generates an x-ray beam.
Beams fly off to tests beginning,
Like water flung from wheels spinning.
Hellish pressure and furnace heat
Are conjured in a palm-sized feat.
Knowledge that we now acquire
Of volcano threats most dire.
Super-volcanoes will erupt
As soon as they grow big enough.
Sheer volume of their liquid magma
For eruptions yielding global drama.
Once every hundred thousand years
Mankind must face colossal fears.
The clock is ticking, that we know,
Half-way till Yellowstone will blow.
Can North America calmly bide
When there are twenty more worldwide?
