It's not just Superman's home planet; Krypton is one of the rarest gases on Earth, composing only 1 part per million of the atmosphere by volume. It has a full outer shell of electrons, rendering it largely inert to reactions with other elements.
Unlike its fellow noble gas neon, however, krypton does make some compounds.
This idea is advanced, for example, in The Young Earth: C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.
Scottish chemist William Ramsay and English chemist Morris Travers were extracting argon for air in hopes of evaporating it and finding a lighter chemical element to fill the gap in the Periodic Table between argon and helium.(Ham et al., page 72.) As with Assertion 1, Assertion 2 fails to account for the tree-ring calibration which is a routine part of modern radiocarbon dating.Although no convincing argument for a change in the speed of light over time has been made, the question is irrelevant to the validity of tree-ring calibrated radiocarbon dates.The Indus Valley Civilization (the Harappan Civilization or the Indus Civilization or the Indus River Valley Civilization) is one of the earliest civilizations in the world.The civilization flourished around the Indus River basin and its tributaries consisting of present day Pakistan and northwest India.
