Even these seemingly precise representations, often based on satellite estimates of ocean depths, are not all that revealing. They’re rather like throwing a wet blanket over a table set for a fancy dinner party. You might see the outlines of four candelabras surrounded by a dozen chairs, perhaps some drinking glasses if the blanket’s really wet. But that’s about it. You wouldn’t see the utensils and plates, let alone what’s for dinner.
That’s not only a brilliant analogy; it also makes me hungry!
