Someone check my math for me please -
The volume of a sphere is calculated as (4/3)*pi*r^3
The radius ® of Earth is 3959.8 miles
(4/3)pi*(3959.8^3) = (4/3)pi(62,089,727,515.192) = (4/3)195,060,631,825.119 = 260,080,842,433.492 cubic miles
which is slightly over 260 billion cubic miles... for the volume of the entire planet.
But Yellowstone has nearly TWICE that volume of molten rock contained within it - almost twice the entire Earth, contained within a small portion of Earth.
I think the bigger story here is that NASA has discovered Hammerspace!

Diogenes was eating bread and lentils for supper. He was seen by the philosopher Aristippus, who lived comfortably by flattering the king.
Said Aristippus, ‘If you would learn to be subservient to the king you would not have to live on lentils.’ Said Diogenes, ‘Learn to live on lentils and you will not have to be subservient to the king.’
