NASA scientist: 'ET may have already visited us'

Posted on Tuesday, 4 December, 2018 | Comment icon 74 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.

What you call "ridiculous" the NYT calls well vetted and the members of said group, well established and credentialed.  BYW, toast, did any of you skeptics ever figure out where those vids came from and what they really represent?     PS: Perhaps you should also explain how a F-18 super hornet pilot aboard the USS Nimitz and who was in the cockpit when the vid was filmed was able to go on FOX TV and talk about it. Wouldn't that be violating military policy?

The reddit discussing TTSA is quite damning.

Sounds like you're shooting for the negative here, GD. Will you equally dispose of pilot Fravor's interview on FOX as useless, lying chatter, too? Face facts.. for the vids to come out and Fravor and two other members of the Nimitz to speak out could never happen without tacit approval of the government. and yet.....?

It's surprising that some members apparently think each and every post exists in isolation, or can't conceive of the development of subthreads. Read what I responded to. The purpose of TTSA is to improve Tom DeLonge's hip pocket. It's reasonable for investors to seek guarantees. However, your suggestion of tacit approval is doubtful. I'm sure there was much correspondence to organise the transaction. Why is Fravor doing these interviews? I don't know.  Why did Michelle Obama appear on NCIS?

We all go to work because of the paycheck at the end of the week.  A physics proff writes a physics text because of the money but that does not mean the text is a hoax. You'll have to better than say "he made money" to prove the production fake. Go read the NYTimes link right above. They talked about the vetting to reassure the reader that it is no hoax. Also think about what happens to three Nimitz sailors (1 pilot) that publicly talk about classified material. You have a ways to go, me boy. But I k now how it goes in here, NO amount of evidence budges people. Most in here remain at absolute ... [More]

Its tabloid news, I think that explains a great deal. The UFO sites followed Kimbler closely. Realistic people predicted the outcome.

Yes we get a paycheck to actually produce something. A publicly listed company, and it's employers have to aim to provide value to shareholders.  DeLonge addresses rumours about debt via Instagram. What ways do I have to go, sonny? I don't have an opinion on the Tic Tac video.  Why should I?  It says: Nothing to get excited about. However, investing in TTSA is not money well spent.
