    Planets with Stabilizing Moons May Be Common: “The Earth’s comparatively massive moon, formed via a giant impact on the proto-Earth, has played an important role in the development of life on our planet, both in the history and strength of the ocean tides and in stabilizing the chaotic spin of our planet. Here we show that massive moons orbiting terrestrial planets are not rare. A large set of simulations by Morishima et al. (Morishima, R., Stadel, J., Moore, B. [2010]. Icarus. 207, 517–535 [cf. http://arxiv.org/pdf/1007.0579 ]), where Earth-like planets in the habitable zone form, provides the raw simulation data for our study. We use limits on the collision parameters that may guarantee the formation of a circumplanetary disk after a protoplanet collision that could form a satellite and study the collision history and the long term evolution of the satellites qualitatively. In addition, we estimate and quantify the uncertainties in each step of our study. We find that giant impacts with the required energy and orbital parameters for producing a binary planetary system do occur with more than 1 in 12 terrestrial planets hosting a massive moon, with a low-end estimate of 1 in 45 and a high-end estimate of 1 in 4.” http://arxiv.org/pdf/1105.4616

    NSA Document Admits ET Contact: “Recently a series of radio messages was heard coming from outer space. The transmission was not continuous but was cut by pauses into pieces which could be taken as units, for they were repeated over and over again. The pauses show here as punctuation. The various combinations have been represented by letters of the alphabet, so that the messages can be written down. Each message except the first is given here only once. The serial number of the message has been supplied for each reference”:

    History & wording:

    It is curious, to say the least, that this document was cleared for release on October 21, 2004. Why was that? Because the NSA did not release it into public information until April 21, 2011. Though cleared for release, the NSA had been stonewalling it along with hundreds of other NSA documents about contact with UFOs and extraterrestrials until they lost the lawsuit brought by Peter Gersten, a lawyer from Arizona. When they well and truly lost, the judge’s order had to be carried out, and the documents had to be released. [...]

    Dr. Campaigne’s presentation to the NSA on decoding the extraterrestrial messages was not a hypothetical exercise. I contacted someone who is formerly associated with the NSA and still has TS clearance, and asked him to view the document. I asked him to give me his take on it. There was no question about its authenticity since it was published in the NSA Journal, and was released by the NSA on their web site. What I wanted to know was whether this document had any particular impact or importance (other than its startling revelations) for someone familiar with the inner workings of the NSA. It did.

    My contact told me that he was blown away by the wording of the document. He said that NSA communications are filled with words like “possibly” , “allegedly”, and “thought to be”.

    He said, “This document has none of the normal NSA disclaimer words in it. They just come out and say ‘we received messages from outer space’ and this is the way to decode those messages.”

    I asked, “What does that mean to you?”

    His reply was instant.

    “Disclosure, pure and simple. They aren’t making any fanfare about it, but there it is. They have just made open disclosure.” http://www.ufodigest.com/article/official-et-disclosure-nsa-document-admits-et-contact-kevin-w-smith

    “Planetary anthropic selection, the idea that Earth has unusual properties since, otherwise, we would not be here to observe it, is a controversial idea. This paper proposes a methodology by which to test anthropic proposals by comparison of Earth to synthetic populations of Earth-like planets. The paper illustrates this approach by investigating possible anthropic selection for high (or low) rates of Milankovitch-driven climate change. Three separate tests are investigated: (1) Earth-Moon properties and their effect on obliquity; (2) Individual planet locations and their effect on eccentricity variation; (3) The overall structure of the Solar System and its effect on eccentricity variation. In all three cases, the actual Earth/Solar System has unusually low Milankovitch frequencies compared to similar alternative systems. All three results are statistically significant at the 5% or better level, and the probability of all three occurring by chance is less than 10−5. It therefore appears that there has been anthropic selection for slow Milankovitch cycles [that is, the periodic variations in Earth’s climate that are induced by changes in Earth’s orbit and orientation in space. The key factors here are axial precession (time varying axis orientation), orbital precession (time varying orbital orientation), and time variation in orbital eccentricity (circularity of the orbit)]. This implies possible selection for a stable climate, which, if true, undermines the Gaia hypothesis [that
    is, that life modifies the environment in ways which are beneficial to itself] and also suggests that planets with Earth-like levels of biodiversity are likely to be very rare. [...]

    It is widely recognized that regions of Earth that have stable temperatures (e.g., tropical rainforests) have high levels of biodiversity (see review by Wilson, 2001). The hypothesis that this link is direct and causal is reinforced by the observation that the deep ocean seafloor also has high biodiversity (Sanders, 1968), even though the conditions are, stability excepted, poor and biological productivity therefore low. Further evidence of a link between rapid climate change and loss of species richness has been gleaned from studies of Earth’s glacial-interglacial cycles. The most recent ice ages have resulted in reduced biodiversity within the temperate zones where the greatest changes in climate occurred (see review by Hewitt, 2004). There are, therefore, two independent lines of evidence that support the proposition that biodiversity is, in general, lower when climate change is significant.

    The development of an artificial intelligence may lead to the destruction of the human race. What we may need to also consider the possibility that not inventing such an intelligence might be the more dangerous option.

    NASA Scientist Claims Evidence of Alien Life on Meteorite: “[...] Dr. Hoover fractured the meteorite stones under a sterile environment before examining the freshly broken surface with the standard tools of the scientist: a scanning-electron microscope and a field emission electron-scanning microscope, which allowed him to search the stone’s surface for evidence of fossilized remains.
    He found the fossilized remains of micro-organisms not so different from ordinary ones found underfoot — here on earth, that is.
    “The exciting thing is that they are in many cases recognizable and can be associated very closely with the generic species here on earth,” Hoover told FoxNews.com. But not all of them. “There are some that are just very strange and don’t look like anything that I’ve been able to identify, and I’ve shown them to many other experts that have also come up stumped.”
    Other scientists tell FoxNews.com the implications of this research are shocking, describing the findings variously as profound, very important and extraordinary. But Dr. David Marais, an astrobiologist with NASA’s AMES Research Center, says he’s very cautious about jumping onto the bandwagon.
    These kinds of claims have been made before, he noted — and found to be false.
    “It’s an extraordinary claim, and thus I’ll need extraordinary evidence,” Marais said.
    Knowing that the study will be controversial, the journal invited members of the scientific community to analyze the results and to write critical commentaries ahead of time. Though none are online yet, those comments will be posted alongside the article, said Dr. Rudy Schild, a scientist with the Harvard-Smithsonian’s Center for Astrophysics and the editor-in-chief of the Journal of Cosmology.
    “Given the controversial nature of his discovery, we have invited 100 experts and have issued a general invitation to over 5,000 scientists from the scientific community to review the paper and to offer their critical analysis,” Schild wrote in an editor’s note along with the article. “No other paper in the history of science has undergone such a thorough vetting, and never before in the history of science has the scientific community been given the opportunity to critically analyze an important research paper before it is published, he wrote. [...]”
