Is there anybody hiding there in the dark?

(Chief Inspector Clouseau:The Pink Panther Strikes Again)

Seems we may have neighbours out there in the dark. Or we had nieghbours 1.5 billion years ago. And if they are still there, they'll think we aren't here because we weren't here when they were there. Oh my...

Pulsar or possibly a quasar.

If the origin of the signal is from 'humans', then the distance implies (as suggested) that their existence was some considerable time ago.
The possibility of 'aliens' having visited Earth (and masterminded the Pyramids) becomes (slightly) more likely . . .

From what I’ve been reading about this the signals are of a nature that hasn’t been detected before, so probably not a pulsar or a quasar as such...but the speculation and some of the TIC comment is similar to that that surrounded the discovery of pulsars in the late 60s.


When observations with another telescope confirmed the emission, it eliminated any sort of instrumental effects. At this point, Bell Burnell said of herself and Hewish that "we did not really believe that we had picked up signals from another civilization, but obviously the idea had crossed our minds and we had no proof that it was an entirely natural radio emission. It is an interesting problem—if one thinks one may have detected life elsewhere in the universe, how does one announce the results responsibly?"[6] Even so, they nicknamed the signal LGM-1, for "little green men" (a playful name for intelligent beings of extraterrestrial origin).

To think that 'we' are the only sentient beings in the vastness of space, is breathtakingly naive, though perhaps understandable from a psychological point of view. 'We' are happy to indulge our egos, variously lauding our achievements over other living forms on planet Earth. To countenance that 'we' are not the only sentient life form and more so that they are eons ahead of our development is too much for the majority of mankind to digest.

Btw, what's happening with that long odd shaped asteroid that was mentioned some months back ?

Hope it's not their fridge switching itself on and off, as I believe turned out to be the case in an earlier incident of unexplained incoming signals.

If you read the article, then 1.5 billion years ago.

Never considered likely once the likes of Erich von Däniken had been thoroughly debunked.

I think it took a look & jogged on.

You are expressing the intuitive highly probabilistic view that given the numbers of galaxies, stars & planets, there must be life elsewhere and some of of it must have developed interstellar travel. It seems an absolute certainty, right? Yet all we know for certain is there are two planets with life on them in our solar system. Us & Mars and Mars is wholly populated by robots!

So there is a difference between what seems likely & what we know. It's a fascinating question & the reason we keep lobbing probes at Mars is we know it had liquid water & Wherever we look on Earth, where we find water, we find life, so finding just one instance of fossilised life on Mars, microbes, little green men or space cows would be profound. It would tell us for certain life is everywhere (assuming life here wasn't seeded by asteroids from Mars or vice versa) Another interesting thing about water is it acts as a solvent with a wide liquid range. It follows in logic that water isn't necessarily required for life, just a solvent which organic chemistry can use. It's possible in theory that life could emerge in the methane lakes of Titan for all we know.

We also know that life arose on Earth pretty much as soon as it could do so & so extrapolating that to similarly endowed planets around other stars that we now are able to observe in large numbers, it seems obvious that the universe is teeming. Yet nothing has ever been observed. As Enrico Fermi famously said: Where are they?

The Fermi paradox is a fascinating topic all on it's own & I won't write it all out here but if you wonder where they all are, then have a look at things like the great filter, the Drake equation, self destruction of intelligent life even relativity ruling out fast interstellar travel.

Decent wiki:

Apart from the 'Fermi Armwrestle' setting out the premise that if 'they' were out there, 'they' would have made contact by now, I'd say "Fair enough", but if you look at mankind today, with all the wondrous technological advances in the last 100 years, we are still a VERY basic lot, still mostly obsessed by eating, drinking, fighting and [email protected]@king. For the most part we are self interested, short-termist, We ignorantly abuse our habitat, oblivious to our actions and pass our sins onto the following generations. If, and it is an if, until concrete proof exists, why would highly advanced non-humans WANT to have meaningful discourse with us humans ? They might keep a distance and observe, rather like naturalists do when observing the behaviour of animals in the wild. Of all the alleged reports of ET interactions, we can happily chop through most with Mr Occam's Razor, but there will be a proportion of the remaining reports that might well be credible. I'm not by any means an avid proponent of little grey men scooting around the cosmos, but take the pragmatic position that there have been enough reported happenings over hundreds of years to suggest that there's a reasonable chance 'they' exist.

The fact that no other galactic civilisation appears to have contacted humans may actually be a sign of great intelligence?

Seems the ultimate in arrogance to assume that any advanced life forms would ever want to contact us.

The Rocky Horror Picture Show had it right...

"And crawling on the planet's face,
some creatures called the human race.
Lost in time
and space
and meaning."

To think that 'we' aren't alone in the vastness of space is no less naive. Good scientists say on the topic: "I don't know" because they really don't.
"Great filter" is definitely worth googleing btw.

It passed between Mercury and Sun and is heading towards outer space at the moment, maybe it has already left our solar system.

What is sad is that given the above, we might be the most advanced civilisation (somebody has to be).

Au contraire mon ami! We are discussing signals from space that could indicate an intelligent civilisation somewhere. Many take the position that mankind exists in glorious isolation, I see it differently. "They haven't made contact, therefore they don't exist" say the Fermi-ists, I say that perhaps they find us, as a species, to be primitive and not worthy of meaningful contact at this time. That's all, nothing to do with politics, except that which is guided by human nature, regardless of race, colour or creed. It is what we are are in the main, but with notable exceptions, though sadly things won't change for some time.....

Fermi doesn't say that though. Fermi asks a question, The conclusion must be wrong because it flows from an erroneous starting point. Fermi led to Drake attempting to quantify the issue & a whole bunch of postulations on the subject. My own view is the universe is teeming but I don't know that, I do know we're here & there are untold billions of stars & planets & so I'm a sucker for the numbers game.

Speculation that it was a discarded solar sail.

Of of course that could mean it’s payload was now slowly ingressing the solar system behind it.....

The Drake Equation, given what is currently understood is suggesting that the Milky Way could contain significant numbers of potentially intelligent lifeforms.

But the Fermi conundrum questions why if that is the case, contact has not been made.

Professor Brian Cox in the book HUMAN UNIVERSE is of the opinion that there are significant bottlenecks in the evolution of life that could result in 'intelligent life' being very rare.

Cox really harshes my buzz on that one. I've read a few Jim Al Khalili things on SETI as well & his view is similar. The nuance of it aiui is life arises spontaneously wherever conditions allow but rarely, for all sorts of reasons, gets going to intelligence as we would define it.

On Fermi, it's the other way round. Fermi came up with his paradox in 1950. Drake's equation dates to 1961. Drake took Fermi's paradox & attempted to quantify it. One of the great weaknesses & also strengths with Drake is you can amend the variables to construct an answer either way. Unsurprisingly, people do.
