  • Ancient Earth Remnant Is Inside Earth, Study Says

    06/28/2014 6:53:52 PM PDT · by 2ndDivisionVet · 64 replies
    The Guardian Liberty Voice ^ | June 28, 2014 | Gregory Baskin
    A team from Harvard University presented a study this month that remnants from an ancient Earth exists, right now, inside contemporary Earth. The group believes that their comparisons of isotopic ratios of noble gases from materials deep inside Earth with those near the surface provide testimony that the deep-down material is actually from the Earth that existed before its massive collision with another planet. That immense impact – the largest in geologic history – is what many believe led to creation of the Moon. The currently favored theory about how the Moon originated says that it was formed 4.5 billion...

    Trailer Talk: Eco-Terrorism 'Night Moves' Downplays Own Subject Matter by Christian Toto 31 Mar 2014 Both The Company You Keep and The East, films which portrayed eco-terrorists in a favorable light, tanked at the box office. So is it any wonder the trailer for the new film Night Moves downplays the eco-nature of its protagonists? The thriller casts Dakota Fanning, Jesse Eisenberg and Peter Scarsgaard as three environmental radicals who decide to take action against their corporate targets. Trailers are famous for giving away too much of their stories. In the case of Night Moves, the trailer only touches on...

This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel. While the experiment is operational, views will typically sequence though the different cameras. Between camera switches, a gray and then black color slate will briefly appear. Since the ISS...

    "The heavens reek, the waters below are foul ... we are in a crisis of survival." That's how Walter Cronkite and CBS hyped the first Earth Day, back in 1970. Somehow we've survived since then, and most of life got better, although I never hear that from the worrywarts. Of course, some things got better because of government: We passed environmental rules that got most of the filth out of the air and sewage out of lakes and rivers. Great -- but now we're told that we're in big trouble because greenhouse gases cause global warming. I mean, climate change....

    For scientists who spend time thinking about how planets form, life would be simpler if gas giants like Jupiter and Saturn didn’t exist. According to the standard model of planet formation, called "core accretion," planets form over millions of years as enormous blocks of rock and ice smash together to form planetary embryos, called "protoplanets," and eventually full-fledged planets. Most scientists agree that core accretion is how terrestrial planets such as Earth and Mars were created, but the model can’t convincingly explain how gas giant planets like Jupiter and Saturn came to be. One major problem is that developing gas...

    Line up Mercury, Venus, Earth and Mars according to their distance from the sun and you'll see their size distribution is close to symmetrical, with the two largest planets between the two smallest. That would be no coincidence -- if the pattern emerged from a debris ring around the sun. Brad Hansen of the University of California, Los Angeles, built a numerical simulation to explore how a ring of rocky material in the early solar system could have evolved into the planets. He found that two larger planets typically form near the inner and outer edges of the ring, corresponding...

Chemicals fouling the ocean off the Palos Verdes Peninsula seem to be going away without being cleaned up. Samples taken from the sediment suggest more than 100 metric tons of the banned pesticide DDT and industrial compounds known as polychlorinated biphenyls, or PCBs, have vanished from one of the country's most hazardous sites, almost a 90% drop in just five years.

    Institute for Creation Research ^ | October 28, 2013 | Brian Thomas, M.S.
    Secular scientists used to regard the planetary collision theory as a triumph in explaining several of the moon's specific arrangements. But newfound facts severely debilitate this lunar impact origins theory. According to this new theory, an early Earth collided at a glancing angle with a planet that was one or two times the mass of Mars. Some of the debris launched into orbit around Earth and somehow collected to form the moon. This could explain the moon's peculiar orbit and some of its other properties.1 But, as Bob Jones University astronomy professor Ron Samec noted, recent studies refute even this...

    Earth will be able to host life for just another 1.75 billion years or so, according to a study published on 18 September in Astrobiology1. The method used to make the calculation can also identify planets outside the Solar System with long ‘habitable periods’, which might be the best places to look for life. The habitable zone around a star is the area in which an orbiting planet can support liquid water, the perfect solvent for the chemical reactions at the heart of life. Too far from a star and a planet’s water turns to permanent ice and its carbon...

I’m not sure if spring was a wise time to do this from a horticultural point of view. It seemed to me that, having survived the rigours of winter, these hardy little tusks of plant matter probably wanted to wait undisturbed for the Sun’s warmth to penetrate the blanket of earth above them. But such was the issued command, and so I began to brush away last year’s dead leaves...

A team of scientists has measured the melting point of iron at high precision in a laboratory, and then drew from that result to calculate the temperature at the boundary of Earth's inner and outer core — now estimated at 6,000 C (about 10,800 F). That's as hot as the surface of the sun. The difference in temperature matters, because this explains how the Earth generates...

They have created a map of the spins of electrons deep within the Earth's mantle, which could be used to reveal the as-yet-unseen force as well as the strange particles – known as "unparticles" – that might carry it. We currently know of four fundamental forces: gravity, electromagnetism and the strong and weak nuclear forces. The hypothetical fifth force can be thought of as a version of magnetism that does not weaken as quickly with...

The global wipeout that ended the Permian era, before dinosaurs, wiped out nearly all of the world's species. Mass extinctions like these in Earth's history are usually followed by a "dead zone", a period of tens of thousands of years before new species crop up. But the early Triassic dead zone lasted millions of years, not thousands. Boffins now reckon that the extra-long five million year dead zone was caused by screaming...

"Small asteroid 2012 TC4 will safely pass Earth Oct 12 at just .25 the distance to our moon's orbit," scientists with NASA's Asteroid Watch program wrote...

    From the file of “Things that would really be catastrophic”. Did a meteor have a role in a major shift in Earth’s Climate?The start of the Quaternary period (2.588 million years ago, where the Pliocene became Pleistocene) coincides with evidence of a mega tsunami in the South Pacific.The Eltanin Meteor fell into the South Pacific 2.5 million years ago setting off a (likely) tsunami that was hundreds of meters high and theoretically pushed mass material into the atmosphere which may have contributed to the cooling the globe had already started on. This meteor was hard to detect because it hit...

    Billions of years ago, before Earth's atmosphere had oxygen, it periodically possessed a "haze" of organic chemicals including methane, boffins have discovered. During these periods the planet's air was more like that of Titan, ice moon of Saturn, than the stuff we breathe today. "Models have previously suggested that the Earth's early atmosphere could have been warmed by a layer of organic haze," says Dr Aubrey Zerkle of Newcastle uni. "Our geochemical analyses of marine sediments from this time period provide the first evidence for such an atmosphere." According to Zerkle and his colleagues, during the period 2.5 to 2.65...

    As if the inside story of our planet weren’t already the ultimate potboiler, a host of new findings has just turned the heat up past Stygian. Geologists have long known that Earth’s core, some 1,800 miles beneath our feet, is a dense, chemically doped ball of iron roughly the size of Mars and every bit as alien. It’s a place where pressures bear down with the weight of 3.5 million atmospheres, like 3.5 million skies falling at once on your head, and where temperatures reach 10,000 degrees Fahrenheit — as hot as the surface of the Sun. It’s a place...

    This weekend will provide the full Moon’s closest approach of the year to Earth. On Saturday, May 5, 2012 the Moon could appear as much as 14% bigger and 30% brighter than other full Moons of 2012, according to some calculations. Will you notice it? Not if you haven’t really been paying attention, or have a reference point to compare it to other full Moons. And it certainly won’t have any adverse effects on Earth, as this closest approach happens every year — just a fact of orbital mechanics. But perhaps a great way to celebrate Cinco de Mayo is...

    We have heard a lot about exoplanets in the past year. But for all the talk about these planets, which orbit a star other than our sun, we still haven't actually seen one. One tool could change that, giving us our first look at a distant planet that could be the next best thing to Earth. Currently, scientists detect an extra-solar planet by measuring the dimming of its star as the planet passes between it and our line of sight (this is known as the Transit Method). By observing the way the star's light shines around the planet, it's possible...

    As gasoline prices continue to rise, President Obama on Thursday pushed back on attacks from Republicans that he is blocking the Keystone XL oil pipeline and is against drilling, arguing his administration has added enough new oil-and-gas pipelines to "encircle the Earth and then some." Obama highlighted his support for the southern leg of the controversial Keystone pipeline, which would carry oil from Cushing, Okla., to refineries on the Gulf Coast. Appearing before a backdrop of oil pipelines in Cushing, Obama said he was making construction a priority through an executive order issued Thursday that instructs federal agencies to expedite...
