White House Says No Aliens Among Us

The White House has responded to two petitions asking the US government to formally acknowledge that aliens have visited Earth and to disclose to any intentional withholding of government interactions with extraterrestrial beings. “The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race,” said Phil Larson from the White House Office of Science & Technology Policy, on the WhiteHouse.gov website. “In addition, there is no credible information to suggest that any evidence is being hidden from the public’s eye.”Environment Clean Generations

5,387 people had signed the petition for immediately disclosing the government’s knowledge of and communications with extraterrestrial beings, and 12,078 signed the request for a formal acknowledgement from the White House that extraterrestrials have been engaging the human race.
“Hundreds of military and government agency witnesses have come forward with testimony confirming this extraterrestrial presence,” the second petition states. “Opinion polls now indicate more than 50% of the American people believe there is an extraterrestrial presence and more than 80% believe the government is not telling the truth about this phenomenon. The people have a right to know. The people can handle the truth.”

These petitions come from an Obama Administration initiative called ‘We the People’ which has White House staffers respond and consider taking action on any issue that receives at least 25,000 online signatures. Regarding these two petitions, the White House promised to respond if the petitions got 17,000 or more signatures by Oct. 22.


Larson stressed that the facts show that there is no credible evidence of extraterrestrial presence here on . He pointed out that even though many scientists have come to the conclusion that the odds of life somewhere else in the Universe are fairly high, the chance that any of them are making contact with humans are extremely small, given the distances involved.
But that doesn’t mean we aren’t searching, there is just no evidence yet.Environment Clean Generations Larson mentioned SETI (correctly noting that this at first was a NASA effort, but is now funded privately) keeping an “ear” out for signals from any intelligent extraterrestrials, with none found so far. He also added that the Kepler spacecraft is searching for Earth-like planets in the habitable zones around other stars, and that the Curiosity rover will launch to Mars this month to “assess what the Martian environment was like in the past to see if it could have harbored life.”
Regarding any evidence for alien life, all anyone has now is “statistics and speculation,” said Larson. “The fact is we have no credible evidence of extraterrestrial presence here on Earth.”

Whether or not this will appease or satisfy any conspiracy theorists or UFO believers is yet to be seen, but it is gratifying to see the respond in such a no-nonsense manner.
UPDATE: The Paradigm Research Group, one of the organizations sponsoring the petitions, has issued a statement saying, “As expected it was written by a low level staffer from the Office of Science and Technology Policy – research assistant Phil Larson. The response was unacceptable.”

If Aliens Exist Will They Kill Us?



We're an inquisitive lot, we humans. But could our inquisitiveness ultimately kill us? In a documentary by Stephen Hawking the world's most recognized physicist speculates about different forms of alien life and explores efforts under way to search and communicate with intelligent extraterrestrial civilizations. However, he cautions that perhaps we shouldn't be advertising our location; perhaps we should just sit back and listen instead.

                 So, Hawking takes us on a thrilling ride through some potential shapes aliens may take, but using life on Earth as the blueprint.

                At one point in the documentary, Hawking describes how feet would be useful for any life form that has evolved on a solid surface. He also points out that eyes are handy too. 

               Eyes and feet have been optimized to function on our planet, so perhaps some variation will be found attached to a life form thriving on a distant world. When speculating about alien life it's open season; anything goes. But we only have experience of Earth Brand™ Life, so that's an obvious place to start. We know (to the best of our ability) that the laws of physics are universal, it seems logical to assume life is too (apart from some variations in detail).  

              If there's life, there's the potential that in some world orbiting some star in some galaxy, an intelligent space-faring race may be as inquisitive as we are, pondering their place in the cosmos and looking for other civilizations like their own.  
     
        In an effort to find intelligent civilizations, we have to assume that they're a bit like us, so the first thing we look for are radio waves. 

        The Search for Extraterrestrial Intelligence (SETI) has been doing this for 50 years, carefully listening for any ET call home. If humans communicate via radio waves, there's a good chance that another intelligent civilization has done the same. 

        Alas, apart from one isolated case, SETI has turned up zero evidence for the existence of extraterrestrial intelligence. This means we are either wrong to be listening out for ET's radio transmissions, we haven't given it enough time or (and this is the downer) there's no other intelligent life out there. 

         I strongly suspect that given the sheer scale of the universe, and the mind-boggling quantities of exoplanets orbiting countless stars in countless galaxies, there's intelligent life other than us. Granted, there's no evidence of ET, but as Hawking points out in his documentary, his mathematical brain cannot discount the possibility of alien intelligence when there are endless possibilities inside the hundreds of billions of galaxies we know are out there. 

                 So we continue to listen out for the signal from aliens through ever more ingenious methods. But we are transmitting too. There have been numerous attempts at "Active SETI" or Messaging Extraterrestrial Intelligence (METI), where we transmit our presence to the cosmos. The most basic of these methods was to attach our information to the Voyager and Pioneer probes in the 1970s. 

                This space-age "message in a bottle" has a very limited probability of ending up in the hands of an alien species. However, more recent modes of communication have included beaming our own radio waves into space attempting to make contact.

                It's also worth remembering that our planet started to get "radio noisy" when we started transmitting radio and television signals about 100 years ago. Some of these transmissions will have "leaked" into space. 

Therefore, if anyone is looking for us within 100 light-years from Earth, they might have already heard us. However, 100 light-years is very small in cosmic distances. For a galaxy measuring 100,000 light-years across, our signal has only reached 0.1 percent of the Milky Way.   

           Okay, so what if we start blasting out signals advertising our presence? To assume alien civilizations will be friendly and welcome us with open arms seems grossly naïve. As Hawking points out, if there's one thing we've learned from our own evolution, although we might have the best of intentions, we've rarely "come in peace."

           Mankind is all about resources; imagine if a more advanced civilization sees Earth as a bountiful supply of sustenance and sees our civilization as nothing more than ants crawling over a big juicy apple. Wouldn't they just wash us off? 


           And so this is where Hawking leaves us, pondering our fascination with broadcasting our presence into space. Wouldn't it just be better for us to stay as quiet as we can, listening rather than shouting from the rooftops?

           Personally, I think Hawking has a point. Although it might take hundreds, thousands or even millions of years for our signal to reach an intelligent “ear,” if that ear isn't a friendly one, we've basically decided our future-Earth's fate. 

             If there are any human decedents beginning to spread beyond our planet, it would be a real downer for an aggressive alien invasion to suddenly appear in response to our ancient transmissions. I'm sure we'd look back at our idiotic past-selves with anger when we realize we are living in the backyard of a vastly superior alien race intent on eradicating the human infestation that's spreading down their garden path. 

            On the other hand, we might contact a race of "huggy" aliens who genuinely want to be our friends. But on the off chance that we might get eaten, I'm with Stephen Hawking. Let's be careful about how we advertise ourselves, shall we?
