NASA expert says alien life may have ALREADY visited Earth.

  1. Believes that alien life may have gone far beyond human technology
  2. Could be 'very different from traditional carbon based life humanity is used to'
  3. May even have mastered interstellar travel.




Silvano P. Colombano, who works in NASA's Intelligent Systems Division, believes we may have missed it, as it could be very different from the traditional carbon based life humanity is used to. 

Silvano P. Colombano,
NASA's Intelligent Systems Division
He believes that current thinking about extraterrestrial life is far too narrow. 


'I simply want to point out the fact that the intelligence we might find and that might choose to find us (if it hasn't already) might not be at all be produced by carbon based organisms like us,

Colombano wrote in a paper first presented at a 'Decoding Alien Intelligence Workshop' in March organized by the Search for Extraterrestiral Intelligence.







He believes that alien life may have gone far beyond human technology, and may even have mastered interstellar travel. 

'We need to re-visit even our most cherished assumptions,' he wrote. 

'How might that change the above assumptions about interstellar travel?' he wrote.

'Our typical life-spans would no longer be a limitation (although even these could be dealt with multi-generational missions or suspended animation), and the size of the 'explorer' might be that of an extremely tiny super-intelligent entity.

'Considering further that technological development in our civilization started only about 10K years ago and has seen the rise of scientific methodologies only in the past 500 years, we can surmise that we might have a real problem in predicting technological evolution even for the next thousand years, let alone 6 Million times

He also warned that radio waves, could be out of date. 

He called for physicists to take part in 'speculative physics', grounded in our most solid theories but 'with some willingness to stretch possibilities as to the nature of space-time and energy' and to 'consider the UFO phenomenon worthy of study'




WHAT ARE FAST RADIO BURSTS AND WHY DO WE STUDY THEM?

Fast radio bursts, or FRBs, are radio emissions that appear temporarily and randomly, making them not only hard to find, but also hard to study.

The mystery stems from the fact it is not known what could produce such a short and sharp burst.

This has led some to speculate they could be anything from stars colliding to artificially created messages.

The first FRB was spotted, or rather 'heard' by radio telescopes, back in 2001 but wasn't discovered until 2007 when scientists were analysing archival data.

But it was so temporary and seemingly random that it took years for astronomers to agree it wasn't a glitch in one of the telescope's instruments. 

Researchers from the Harvard-Smithsonian Center for Astrophysics point out that FRBs can be used to study the structure and evolution of the universe whether or not their origin is fully understood.

A large population of faraway FRBs could act as probes of material across gigantic distances. 

This intervening material blurs the signal from the cosmic microwave background (CMB), the left over radiation from the Big Bang. 


A careful study of this intervening material should give an improved understanding of basic cosmic constituents, such as the relative amounts of ordinary matter, dark matter and dark energy, which affect how rapidly the universe is expanding.

FRBs can also be used to trace what broke down the 'fog' of hydrogen atoms that pervaded the early universe into free electrons and protons, when temperatures cooled down after the Big Bang. 





P.Silvano Colombano Ph.D.

NASA – Ames Research Center

Member of AIAA Space Architecture Technical Committee (SATC) – Construction Subcommittee

Dr. Silvano Colombano received an M.A. in Physics and a Ph.D. in Biophysical Sciences from the State University of New York at Buffalo. He has spent most of his working career at NASA-Ames Research Center first as a researcher in Closed Ecological Life Support Systems (CELSS) and later in Artificial Intelligence and Robotics. He began the development work on the Astronaut Science Advisor (a.k.a. PI-in-a-box) and managed the project until its deployment on SLS-2 (Space Shuttle STS -58) in 1993. He has been doing research and development work in Artificial Neural Networks, Genetic Algorithms and Fuzzy Logic in the Intelligent Systems Division at NASA-Ames. He is author or co-author of over 80 technical publications. He lead a group in “Evolutionary Biotronics”, comprising projects in Evolutionary Hardware, Modular Cooperative Robotics and Artificial Life, and organized a workshop on Self-Sustaining Robotic Ecologies called “Robosphere “ in 2002, 2004 and 2006. He has been interested in self-deploying robotic space structures. Since 2008 he has been focusing on Systems Engineering for the Orion space capsule flight S/W and, currently, on a Fault Management System for the Deep Space Habitat.
