Some may assume that he has way too much time on his
hands; others may applaud his sense of wonder. Either way, Professor Tim
Leighton took the initiative to work out
what
a methanefall on Titan would sound like, based on what we already know
about Titan's gravity and atmosphere. (Since Titan's average temperature
is so cold that water exists only in its solid state, and the temperatures
hover around the triple point of methane, Titan can't have
waterfalls...unless you're talking about cliffs of ice collapsing,
and that's not the same thing.)
