reported last week that the White House denied that it has discovered aliens in space or that they have made contact with mankind. They did, though, admit that the chances of another species in space are high.
But is there advanced alien technology in space or even an extraterrestrial species and we are not noticing them? Two Pennsylvania State University scientists believe it is a possibility.
According to a paper
published by Jacob Haqq-Misra, of Rock Ethics Institute, and Ravi Kumar Kopparapu, of the Earth and Environmental Systems Institute, it is put forth that our deep-space probes could be too small and hidden for other civilizations to notice. Also, alien spacecraft and/or probes the size of a yacht could be in front of us but we are unaware.
To determine if we have examined space closely enough, the two researchers calculated how much of our solar system would need to be searched. They concluded that a large majority of our searches in space have not been good enough.
“The vastness of space, combined with our limited searches to date, implies that any remote unpiloted exploratory probes of extraterrestrial origin would likely remain unnoticed,” wrote the two scientists.
“Extraterrestrial artifacts may exist in the solar system without our knowledge simply because we have not yet searched sufficiently. Few if any of the attempts would be capable of detecting a 1 to 10 meter probe. Searches to date of the solar system are sufficiently incomplete that we cannot rule out the possibility that nonterrestrial artifacts are present and may even be observing us.”
They are optimistic, though. Haqq-Misra and Kopparapu say that since we surveying the moon, Mars and elsewhere in the universe, it is quite possible to discover something sooner or later.
