Take the following as truth: As Melville pointed out, if a sperm whale can spend more than an hour swimming at depths of up to 6,000 feet, and a sperm whale is composed mostly of gas (air-filled lungs and blubber), then Boyle's law would dictate that, as Spruch puts it, a whale of regulation size at the surface should, at the pressures a thousand fathoms down, decrease its volume to the size of a bathtub!
Then the following statement: "A sperm whale goes deeper than any other whale." is true, false, or inconclusive?
Answer: Inconclusive
