New research shoots down expanding Earth theory

August 18, 2011PASADENA, Ca. – Since Charles Darwin’s time, scientists have speculated that the solid Earth might be expanding or contracting. That was the prevailing belief, until scientists developed the theory of plate tectonics, which explained the large-scale motions of Earth’s lithosphere, or outermost shell. Even with the acceptance of plate tectonics half a century ago, some Earth and space scientists have continued to speculate on Earth’s possible expansion or contraction on various scientific grounds. Now a new NASA study, published recently in Geophysical Research Letters, has essentially laid those speculations to rest. Using a cadre of space measurement tools and a new data calculation technique, the team detected no statistically significant expansion of the solid Earth. So why should we care if Mother Nature is growing? After all, Earth’s shape is constantly changing. Tectonic forces such as earthquakes and volcanoes push mountains higher, while erosion and landslides wear them down. In addition, large-scale climate events like El Nino and La Nina redistribute vast water masses among Earth’s ocean, atmosphere and land. Any significant change in Earth’s radius will alter our understanding of our planet’s physical processes and is fundamental to the branch of science called geodesy, which seeks to measure Earth’s shape and gravity field, and how they change over time. Enter an international group of scientists led by Xiaoping Wu of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., and including participants from the Institut Geographique National, Champs-sur-Marne in France, and Delft University of Technology in The Netherlands. The team set out to independently evaluate the accuracy of the International Terrestrial Reference Frame and shed new light on the Earth expansion/contraction theory. The result? The scientists estimated the average change in Earth’s radius to be 0.004 inches (0.1 millimeters) per year, or about the thickness of a human hair, a rate considered statistically insignificant. “Our study provides an independent confirmation that the solid Earth is not getting larger at present, within current measurement uncertainties,” said Wu. –Science Daily

    Just listen to all the double talk, the solid earth is not getting larger the WU says, duh. Naturally it expands by the means of a substance helping it do so, duh, no PhD here folks and Nothing to See, please move along……

    Expanding Earth Theory is fact. Don’t believe a thing they say trying to dismiss it. The evidence for the Expanding Earth is overwhelming and makes to much sense.

  4. What a bunch of morons! If the Earth is expanding by .004 inches per year, that is well over six miles added to the Earth’s radius in just 100 million years. This is fully in agreement with the Expanding Earth hypothesis and actually proves the hypothesis is valid. And yet, in their stupidity, they claim it is statistically insignificant. In the course of the Earth’s lifetime of five billion years, the diameter, assuming a steady expansion rate, the Earth will have increased in diameter by nearly 650 miles! Considering the Earth is now 8000 miles in diameter, that is very significant. That is an 8% increase in size. Again, that is assuming the expansion rate is constant.

    That the Earth is expanding at all, as opposed to having a net zero growth, is proof that the Earth is expanding. The Earth is expanding right now, and there is significant geological evidence to support the expansion of the Earth, so that is proof in favor of the Expanding Earth theory, not proof against it. It makes you want to scream at the level of ignorance in the scientific community.

    Appears to me, that this is NASA attempting to debug the truth – there are clearly events occurring
    they do not want to attention drawn to.

    Considering that space dust is continually falling to earth, how can it not be expanding?

    Scientists also estimate between 36 and 166 meteorites larger than 10 grams fall to Earth per million square kilometers per year. Over the whole surface area of Earth, that translates to 18,000 to 84,000 meteorites bigger than 10 grams per year. But most meteorites are too small to actually fall all the way to the surface. Estimates for the total mass of material that falls on Earth each year range from 37,000-78,000 tons. Most of this mass would come from dust-sized particles. (This study was led by P. A. Bland and was published in Monthly Notices of the Royal Astronomical Society.)
    So their argument is bunkum, because as stated above the earths mass increases by 37,000 to 78,000 tons per year

  9. At the rate of .004 inches per year, that is the same thing as saying nearly 52 cubic kilometers of new material is appearing on the Earth each year. It surely is not falling from the sky. That new material is being generated within the Earth via fusion (hot and cold) and the Casimir effect.

    Not only does the physical evidence show the Earth is expanding, but it also provides good evidence that matter is, in fact, being created throughout the Universe. This occurs not only on Earth, but also on all stars and most other planets. Stars are observed to expand with time. The Moon is observed to have stretch marks from expansion. All planets show stretch marks. The moons around Jupiter and Saturn are observed to be producing and ejecting matter into space at high rates.

    The physical evidence shows the Earth is expanding, but they have to deny it because it throws a big wrench into the “matter is neither created nor destroyed” myth.

  10. “within current measurments uncertaintees”, says Mr. Wu.

    With all respect to him, I think he made a big faux pass, by allowing himself and his name to be put into a statement of this manner. This is a political statement, and most certainly not worthy of a scientist. I pretty much think Mr. Wu killed his scientific credability. And also has discredited his countries scientific abilities, in the future. This is a short term solution, by NASA, and using a Mr. Wu as a “scapegoat” in the process.

    There are two things you cannot argue, the obvious and the impossible. Plate Tectonics being the impossible, and earth changes being the obvious.

    What this article doesn’t explain is, was there a sudden expansion in the past and what caused it. It only notes that current expansion has subsided. For now.

    My problem with their findings that the earth is fixed in size has to do with their readings being done primarily through satellites. If the earth were increasing in mass, it would effect the orbits of the satellites. Their measurements are only valid if you assume the earth isn’t changing in mass, something that has only been assumed but never proven.

    The earth gaining mass may sound crazy since matter cannot be created from nothing, but we know that most matter in our galaxy is dark matter. It has mass but can pass right through earth. Is it that far fetched to think that some of that dark matter are actually fragments of what make up protons and neutrons and that they form together inside earth? Just think of what happens in particle colliders but in reverse. Trillions of neutrinos are passing through you this very second and in rare interactions with matter, neutrinos form electrons.

    The way I see it, the scientific community is arrogant to think it knows enough about our vast universe to rule out the idea that earth can expand. We have barely even scratched the surface in astronomy and particle physics.
