NASA scientist: 'ET may have already visited us'

Posted on Tuesday, 4 December, 2018 | Comment icon 53 comments

What would an extraterrestrial visitor really be like ? Image Credit: CC0 Pixabay
A scientist with NASA's Intelligent Systems Division believes that our idea of alien life is too narrow.
In a recent paper, Silvano P. Colombano theorized that intelligent extraterrestrial life may have already visited our planet and that it may be very different to how we might expect it to be.

"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 produced by carbon based organisms like us," 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."

It is also not unreasonable to assume that any extraterrestrial visitors capable of reaching our planet will almost certainly possess technology far in advance of our own and may have even found a way to travel quickly between star systems.

"We need to re-visit even our most cherished assumptions," Colombano wrote.

"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 !"

Radio waves, for instance, travel at the speed of light, making communication over interstellar distances problematic. But what if there was another way to send messages to other worlds ?

It could be that we have barely even scratched the surface of what's possible.

Do you really think we'll be around for a million years? The ET's I think exist are mostly unintelligent.

I hope so LOL. Billions, maybe. If humans can build mega space ships that can ferry thousands AND develop a fast way to travel, the human species has a chance. "mostly"... perhaps.  I have a theory. I think that once life forms come into being, (amoeba), you cannot under normal circumstances stop the cycle of life from occurring. Meaning, it will evolve all the way to the highest level, whatever that is.   (is the human species the last of the evolution pyramid? we don't know YET)

He prb means mainstream news. A lot people think if it's not on the mainstream news it isn't real. When mainstream news is more propaganda then anything.

And may have even created humans. A little DNA from a Neanderthal and some DNA from themselves sounds about right for the giant leap so fast.

And I am sure they don't travel at all the same way we do. I suspect they can travel interdimensionally and travel place to place just by thought. Consciousness can move anywhere in a blink of an eye.

Well, TruthSeeker (love that nic), don't take me wrong here, but MainStream Media (NYT, CNN, BBC) DID carry the three videos that the military released of UFO's and of a Navy pilot testifying of his experience with them (CNN).  But you'll be busy meeting anyone in your travels here at UM that actually *believes* that they saw intelligently constructed and flown UFO's. Yes, they are standing in deNile.

That is surprising. I guess they are finally releasing these things slowly. I rarely watch anything mainstream but last year I did catch Fox news covering a UFO. Yea I agree many are in denial here or they just want to argue and make themselves sound!!

I'm sure there's intelligent ETs out there. Just the number of star systems and planets suggests it's highly likely. The bottom line is, if they come here in spacecraft they must have the physical dexterity to build them. This means hands and fingers, they will need eyes to see what they're building, and will most likely have ears as they would have evolved to evade predators as we have. Legs of course would also be a requirement for catching prey and avoiding predators. So their appearance would most likely be 'humanoid' or something very similar. More arms, or more legs, or both. Nature has ... [More]
