A NASA expert says that aliens may have already visited Earth – but we may not have noticed.
That’s because our assumptions about aliens could be drastically wrong – and instead of meaty green creatures in flying saucers, they might be ‘tiny, super-intelligent entities.’
So aliens might have visited, but they were so small (and clever) no one noticed them, says Silvano P. Colombano, who works in NASA’s Intelligent Systems Division.
Colombano explained his theory in a paper presented at a ‘Decoding Alien Intelligence Workshop’ organised by the Search for Extraterrestiral Intelligence.
Colombano wrote, ‘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.
‘We need to re-visit even our most cherished assumptions. How might that change the above assumptions about interstellar travel?’
‘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 that amount!’
