Visitors extra-terrestrial: scientists see a high probability





Decades ago, the physicist Enrico Fermi, which considering the issue of extra-terrestrial civilisations with friends theorists, at a dinner, has dropped the famous quolibet: "Where are they? "This question later became central to discuss the account of cosmic census of people from other planets and possible visitors extraterrestrial (ET) came from afar

Later, it was called the Fermi rumination on the topic "the Fermi paradox" is a story that circulated in the 1950's when scientists began the topic in discussions with colleagues at Los Alamos, New Mexico. The reflections on the likelihood of planets like Earth, the rise of highly advanced civilizations "out of here," and interstellar travel-It remains difficult to answer the paradox of Fermi today.

Today a group of U.S. scientists noted that recent astrophysical discoveries suggest that we could find ourselves in the midst of one or more extra-terrestrial civilisations. And they argue that it is a mistake to dismiss all reports on UFOs as evidence of extra-terrestrial visitors predicted theoretically could just be found here.

The researchers made their suggestion in the subject of the Journal of the British Interplanetary Society (JBIS). January / February 2005.
Take any good science magazine and you're sure to see the last puzzle idea about the theory of super strings ......, of worm holes, or expanding space - time itself. In the meantime, the extra-solar planetary detection is on the verge of becoming ordinary.

"We are in a strange situation today where our best physical and astrophysical theories predict that we should experience a visit extra land, any possible evidence of such a threat in the UFO phenomenon is the object of ridicule within our scientific community. "Contests astrophysicist Bernard Haisch.

Haisch, with physicists James Deardorff, Bruce Maccabee and Harold Puthoff, give their arguments in the article JBIS "-Inflation-Theory Implications for Extraterrestrial visit."
Scientists refer to two key discoveries made by Australian astronomers and reported last year that there would be a "galactic habitable zone" in our Milky Way - and in a way more important than his own star on earth, sun, is relatively young compared to the average star in this area - as much as a billion years.
Therefore, researchers explain in their article JBIS that the average alien civilization should be much more advanced and should have discovered the land for a long time. In addition, other research on the assumption at the origin of the Big Bang-known as the theory of inflation - supports the view that they have proposed that our world is immersed in a civilization extra - LAND much greater.

Given the physical progress of billions of years, a buzz around the galaxy is it not possible?
Even today the super string theory is assumed other dimensions, which may be habitable universe adjacent to ours, researchers speculate. It might also be possible to approach the speed of light moving inside and outside of these dimensions

"What we have done is a sort of breakthrough," said Haisch to SPACE.com. "We made the synthesis of various recent discoveries and theoretical issues that collectively indicate a strong likelihood that we should be in the middle of one of the most immense extra-terrestrial civilisations," he said.

Haisch said that the potential size of super strings and wormhole and extension of space-time address the objection "we can not get here from there" often put forward in view of interstellar distances, point to point involved. Also, diffusion models predict that even a single civilization could spread across the Galaxy in a tiny fraction of the age of the galaxy - even at speeds below the light, he said.

Is the scientific community itself can come to consider any evidence coming from mysterious glimpses of strange things by the public?
To a large extent, the scientific community has apparently considered the visit by extra-terrestrial as a nonsense not that serious reflection. Why?
"The dismissal has several causes, each reinforcing the other," Haisch responded. "Most of the comments are probably misinterpretations, delusions and hoax. I have seen people become confused in front of Venus or Sirius when flashing colors low in the sky under the right conditions. Having been put off by this, many scientists have never cared to look further and are happily unaware that there may be something there, "he said.

Deardorff, the lead author of the article in the JBIS, said in a press statement: "this would require some humility in the scientific community to suspend judgement and take at least some evidence of high quality and investigate… but I hope we can get ourselves to do that. "According to Haisch, there is a motivation not only for scientific tolerance on the issue of extra-terrestrials, but a strong scientific prediction that there must be some real signature of extra-terrestrial in the data.

"It potentially change the relationship of the UFO phenomenon in science significantly. This removes the injury "not invented here", indicating that a "yes" to the visit and is exactly the tendency on which our physical and astrophysical theories should be understood as the most likely "concluded Haisch
