Products of the Scientific Revolution and the Age of Enlightenment, Johannes Kepler’s Somnium (1634), Francis Bacon’s New Atlantis (1627), Cyrano de Bergerac’s Comical History of the States and Empires of the Moon (1657) and The States and Empires of the Sun (1662), Margaret Cavendish’s “The Blazing World” (1666), Jonathan Swift’s Gulliver’s Travels (1726), Ludvig Holberg’s Nicolai Klimii Iter Subterraneum (1741) and Voltaire’s Micromégas (1752) are regarded as some of the first true science-fantasy works. Isaac Asimov and Carl Sagan considered Somnium the first science-fiction story; it depicts a journey to the Moon and how the Earth’s motion is seen from there.
Some of these grads are aware that even if we could travel at warp 9 (Star Trek's imaginary multiplication of the speed of light) that it would take about one hundred thousand years to make the edge of the Milky Way Galaxy and upon return, the earth would be about 1.2 million years older than it is today. But why harp on the small stuff.
Despite this oddball moon's many exotic attributes, it actually sports one of the most Earth-like surfaces in our Solar System. Titan may also experience volcanic activity, but its volcanoes would erupt with different ingredients than the molten-rock lava that shoots out from the volcanoes of Earth. In dramatic contrast to what occurs on our own planet, Titan's volcanoes erupt icy water "lava" (cryovolcanism). Titan's entire alien surface has been sculpted by gushing methane and ethane, which carves river channels, and fills its enormous great lakes with liquid natural gas.
"For the smallest craters that we're looking at, we think we're starting to see where the Moon has gone through so much fracturing that it gets to a point where the porosity of the crust just stays at some constant level. You can keep impacting it and you'll hit regions where you'll increase porosity here and decrease it there, but on average it stays constant," Dr. Soderblom continued to explain to the press on September 10, 2015.
