 uranium was not understood until 1945. Although the inevitability of uranium in the core was proposed in 1939 by scientist Walter Elsasser, on the basis that it is the heaviest naturally occurring element, so it would migrate to the core via gravity.
Herndon has demonstrated how a uranium georeactor in Earth's core explains reality better than older scientific ideas, by providing more convincing ways to:
-- Explain the ratios of helium isotopes emitted from volcanoes in Iceland and Hawaii. Those ratios are consistent with the ratios of helium isotopes emitted by a nuclear reactor.
-- Explain why planets such as Jupiter emit far more heat than they absorb from the sun. Herndon thinks they, too, have natural nuclear reactors at their cores. (Because heat is continually generated by the decay of radioactive elements in Earth's crust and mantle -- the regions above the core -- scientists are uncertain whether Earth emits more heat than it receives from the sun.)
-- Explain variations in the intensity of Earth's magnetic field, which fluctuates over time. Herndon has shown that in the core, the georeactor drives the motions of the liquid iron that creates the magnetic field. But the georeactor varies in activity levels over time. Those activity variations, he believes, might explain intensity variations in Earth's magnetic field.
Now, Rob de Meijer and associates at the Nuclear Physics Institute in Groningen, the Netherlands, are planning to demonstrate Herndon's proposals. They're drawing blueprints for a large device that could detect ghostly particles called antineutrinos that have escaped from Earth's core. When put into operation, it will capture antineutrinos that would fly through the roughly 4,000 miles of solid rock and emerge at the Earth's surface.
The European scientists have proposed drilling a shaft more than 1,000 feet deep into the island of Curacao in the Caribbean. They hope to lower into the shaft devices called photomultipliers, which could detect particles from the hypothetical deep-Earth georeactor.
The estimated cost: $80 million. In an e-mail to The Chronicle, de Meijer said he is seeking funding from the Dutch government and industrial consortiums. He and his team plan to visit Curacao in January to take the geological samples needed to design the subterranean antineutrino "antenna," as they call it.
Curacao is a good location for the antineutrino detector because "the island's rocks have relatively few natural radionuclides that could mask the (antineutrino) signal from the Earth's core," the journal Physics World noted in September. The detector could be confused by antineutrinos emitted by commercial nuclear reactors, but Curacao is far enough from the southeastern United States that reactors in Florida won't affect it.
"Dr. Herndon is a brilliant and original thinker. I agree with his proposal" said geoscientist David Deming of the University of Oklahoma.
"The problem with most scientists working today is that they have no knowledge of the history of science," Deming adds. "As late as 1955, continental drift was regarded as the equivalent of alien abductions, Bigfoot and the Loch Ness monster. By 1970, continental drift was an accepted part of the new theory of plate tectonics."
Richard Muller, a noted physicist and author at Lawrence Berkeley National Laboratory in Berkeley. Since the 1970s, Muller has done pioneering research in diverse fields, including cosmology and planetary sciences.
"Herndon's discovery is a very positive contribution to deep Earth science. He raises issues that are worth exploring at some length. " Muller adds. "I consider his work to be 'out of the box' thinking, and as such, it is valuable as a step forward in our understanding of reality."
On a side note, in case you're wondering: Unlike the planet-busting reactor of Superman lore, neither the Gabon reactor nor Herndon's hypothetical deep-Earth reactors could explode like atomic bombs. A-bombs require highly concentrated amounts of fissionable materials that are explosively compressed together in a fraction of a second
