The Legends Must Be True



"... the only explanation possible is that the legends must be true." -- John H. Parker, archaeologist, The Archaeology of Rome, 1877

"... all the talk, all the legends, must be true." -- Paige W. Christiansen, historian, The Story of Mining in New Mexico, 1975

"During my researches into the origin of the Micronians [Homo sapiens] in our most ancient [Zentraedi] records I found an old legend. ... It presented a warning to the Zentraedis [giants] to keep our hands off any Micronian planet. ... It is my considered opinion my Lord [Breetai] that we should cease relations with this planet [Earth] immediately." -- Steve Kramer, writer, Exedore, Zentraedi Minister of Affairs, Robotech: The Macross Saga, Episode 5: Transformation, March 8th 1985

"Then the legends must be true." -- Steve Kramer, writer, Exedore, Zentraedi Minister of Affairs, Robotech: The Macross Saga, Episode 23: Reckless, April 3rd 1985

Another Geological Myth Refuted



Geological science fiction refuted: A ‘cool’ new picture of early Earth.

The first 700 million years of Earth’s 4.5-billion-year existence are known as the Hadean period, after Hades, or, to shed the ancient Greek name,
Hell.

That name seemed to fit with the common perception that the young Earth was a hot, dry, desolate landscape interspersed with seas of magma and inhospitable for life. Even if some organism had somehow popped into existence, the old story went, surely it would soon have been extinguished in the firestorm of one of the giant meteorites that slammed into the Earth when the young solar system was still crowded with debris.

Over the last decade, the mineralogical analysis of small hardy crystals known as zircons embedded in old Australian rocks has painted a picture of the Hadean period “completely inconsistent with this myth we made up,” said T Mark Harrison, a professor of geochemistry at the University of California, Los Angeles.
Those same zircon crystals also show that the modern oceans didn't exist in the Triassic and the Earth was half it's present diameter. Maybe now people can start to realize the mantle is also cold and therefore mantle convection is a myth.
