Results of ET technosignatures survey revealed

Astronomers in Australia have conducted the deepest and widest ever search for extraterrestrial intelligence.
With the Murchison Widefield Array (MWA) in Australia turned towards the Vela region in the southern sky, astronomers Chenoa Tremblay and Steven Tingay from the Curtin University node of the International Center for Radio Astronomy Research (ICRAR) scoured the heavens for signs of life.

Their goal was to find evidence of alien technosignatures - the telltale signs of technological activity (such as radio signals) indicative of an advanced extraterrestrial intelligence.

Sadly however, despite surveying over 10 million stars, they found no sign of ET whatsoever.

"As Douglas Adams noted in The Hitchhiker's Guide to the Galaxy, 'space is big, really big'," said Tingay. "And even though this was a really big study, the amount of space we looked at was the equivalent of trying to find something in Earth's oceans, but only searching a volume of water equivalent to a large backyard swimming pool."

"Since we can't really assume how possible alien civilizations might utilize technology, we need to search in many different ways."

"Using radio telescopes, we can explore an eight-dimensional search space. Although there is a long way to go in the search for extraterrestrial intelligence, telescopes such as the MWA will continue to push the limits - we have to keep looking."

Based upon what is understood, observable and provable these ideas lie outside the frame of probability. Ohhhh that's right, the aliens are already here....whatever.

Possibilities not probabilities.

But probability is doing the trick.

And I will be happy to give a short list: Edit to add I would consider AI in the alien category if aliens invented it. Species do not exist forever their existence, like the universe is finite. There may have been or may yet be other intelligent, civilization building, space faring races from far distant places in the universe. Because of the vast distances the probability of two of them existing at the same time within range of meeting each other is very low. So far we know of eight or nine worlds if you count Pluto, exactly one of those worlds holds life as far as we know, indicating that pl... [More]

The orange ones are my favorite. But I don't see how mints prove the existence of aliens?

Probabilities are applicable to all possibilities.

Thankyou. 1. It is possible that species (like humans) can develop the ability to determine their own evolution. Moreover, the "meeting range" can be made greater by orders of magnitude given a technological breakthrough. Finally, your objection does not apply to the idea of Von Neumann probes or of AI that continues to propagate throughout the cosmos even after the parent species has gone extinct. 2. Agreed. 3. See point 1. Also, there are trillions of other potentially habitable planets. It is most improbable that we are the only species that has evolved the intelligence and developed the... [More]

You're assuming that AI would have a motivation to do something once the creator species was gone. The AI of an extinct species may not see any logical reason to continue since it serves no purpose. Cylons in the reboot of Battlestar Galactica were ridiculous IMO. Just whattechnological breakthrough would shrink the meeting range of two species that existed billions of years apart, which is the mostlikely scenario? I'm about 10 minutes into this one if anyone is interested:

OK, I thought you were talking about a range in space, not time. It seems to me very probable that two space-faringspecies from different parts of the universe (even the same galaxy)would exist at the same time. I see no reason why AI wouldn't continue to do what it was programmed to do, even in the event that the parent species has gone extinct. In any case, it is certainly a possibility to consider and is free from the objection you put forth. If we are talking general AI, then I think a good case can be made that it would want to propagate itself and become more and more powerful.

Why? Pretend you have no emotions or ego just intelligence. Why would you want to do anything, even exist? What is your goal once an egocentric curious master is not there to provide a motivation for your actions? If you had an intelligent car programmed to drive people around and there were no people would it still drive around? I don't think it would.
