The recent announcement by the U.S. government that it has no evidence of extraterrestrial life does not mean that aliens are not with us. Just as long as mankind is not able to see the aliens. The aliens are invisible to humans, says The Daily Mail.
The aliens can disappear even in the solar system, scientists believe the University of Pennsylvania. "The vastness of space, combined with our limited capacity means that any unmanned probe of extraterrestrial origin research is likely to go unnoticed," – the Jacob Haqq-Misra and Ravi Kumar Kopparapu.
According to scientists, humanity is still too poorly known solar system to find it alien. Moreover, modern terrestrial probes are too primitive to see traces of extraterrestrial intelligence. The latest technology is not able to discern objects as small as less than 10 m, the researchers noted.
However, probes of this size is quite capable of flying in interstellar space and to reach our planet. Examples are the U.S. research apparatus Pioneer and Voyager, which had in 1970. have started to travel outside the solar system.
Moreover, the aliens can easily hide even on Earth. "The Earth’s surface is one of the few places in the solar system, which is almost completely understood" – the researchers reported. However, the bottom of the ocean, lush jungles and deep caves can still be a great refuge for aliens. In any case, there still continue to find new kinds of living beings.
Recall the other day, the U.S. government has officially stated that evidence of extraterrestrial life exists, and as evidence of human contact with aliens. But do not rule out their existence somewhere in the universe. This response was followed by postings on the White House Web site.
However, the Obama administration did mention that the search for extraterrestrial intelligence is. For this purpose, a special project of international Search for Extraterrestrial Intelligence SETI (Search for Extraterrestial Intelligence). In February this year, the project has opened access to its database and search algorithm signals from space to all comers. The researchers hope that their efforts to connect Internet users, which together can solve many scientific problems
