"mahāpathavī udake patiṭṭhitā, udakaṃ vāte patiṭṭhitaṃ, vāto ākāsaṭṭho"
(Rhetorical) What does
it mean to be "patiṭṭhitā"?
Paul Heckert: "Earth and Solid Planets Were Once Liquid.
"Surface tension will pull liquids and gasses into a spherical shape but not solids. The fact that Earth, Moon, Mercury, Venus, Mars and the larger moons of Jupiter or Saturn are all spherical tells astronomers that they were once liquid. These worlds are all solid now, but were liquid when they first formed. The smaller moons of Jupiter or Saturn, and asteroids are not spherical because they were never liquid." http://www.suite101.com/content/why-are ... nd-a189153
