Why has SETI detected no signals from extra-terrestrial life?

[RightJab]

I wonder if intelligent life on other planets box, and if they do, what style do they use?

Would they be flashy and eye-catching like a prime Ali, or would they jab, jab, jab, jab, jab, jab, jab, jab, clinch, jab, jab, jab, jab, jab, jab, jab, jab, jab, jab and jab to boring UD after boring UD?

All them jabs, nearly came..... fukin jabs, the best. Love a good jab...


Supposed aliens wouldn't give a flying pig twat about us i'd imagine, even if they where way more advanced than us, they'd watch what we do (hypothetically) and think 'let them kill each other and loot them on our way back home' i would do that and i'm not even one, what if they're more cunning than that idea?....Shit....

Again, on a half serious note, no point looking/listening for 'anyone' now, we really need to be outside our solar system just for a start/chance (hypothetical) of contact with someone, with more advanced equipment than the SETI dishes....
At the very least (galaxy/milky-way) wise we're 'out in the middle of nowhere'. That doesn't help....
But we're the only one's here and the true best though imo..... in the universe....ever. Time.Bladerunner.Arnie Shwartz.

that would be boring, considering they have 2 arms

but what if they have, like, six arms?

What if it's.....Mother Brain!?!?

We'll be OK

We're not just listening for transmissions TO us from them.

We're listening for radio signals from them to each other, and we've not heard anything.

But we've only been broadcasting radio waves for the last hundred years on a planet which is four billion years old. We've only been listening for half that time. We might have missed them! The radio waves may have passed us by and their civilisation been destroyed or even moved past radio communication.

If an intelligent life form 50 light years away had something like SETI, they'd might hear the Beatles on BBC right now and they might hear us broadcasting the news about the JFK assassination later this year.

We've been listening for over 50 years to many locations across the galaxy, and heard no radio transmissions. More recently, SETI focused on planets in the so-called "habitable zones" around sun-like stars, and heard nothing.

But fifty years is a very short time.

But we should keep in mind, the chances of intelligent life evolving on another planet is very unlikely (though not impossible). You see, simple life existed on earth for about 3 billion years before complex life finally evolved, and then various forms of complex life were here more than another half-billion years before humans finally evolved.

Even if we count humans as the first intelligent life on earth, even if we only count them from the invention of agriculture, we have had intelligent life on the planet for 100 times longer than we've been broadcasting and 200 times longer than we've been listening to other planets. It's entirely possible that there is intelligent life close by but that they have never developed our level of technology.

There has to be an ozone layer, a moon to create the tides, giant outer planet(s) like Jupiter to attract dangerous comets, and a stable single star like sol (one without the massive solar flares we observe in so many nearby stars). And we need to be just the right distance from the star, we need enough gravity to hold onto an atmosphere, and our rotation should be within a time frame...

I don't think that all of those things are necessary for life to exist, or for intelligent life to evolve. The main thing is needed is relative stability. For example a moon of a large planet could hold intelligent life. All that intelligence requires is time. Sure, there are things that might happen such as asteroids striking, but those are random events.

The mistake is in assuming that life that we discovered would be just like us.

There should be a lounge for science and religion convo

But fifty years is a very short time.

We've been listening for radio signals that may have happened any time from a few years ago (Epsilon Eridani and Tau Ceti) to over a hundred years ago (Achernar, HD 101364) to millions of years ago (other galaxies) depending on the distance.

Yet we've heard nothing.

Seti is worthless. No intelligent aliens would still be using radio.

[Beercules]

Looking for the wrong thing IMO.


Aliens won't be listening to radio signals.

The key is in those damn black holes duh lol

[MDPopescu]

... Some weeks ago, there was detected a burst a radio waves which is supposed to originate at such a distance in light years that it largely surpasses our solar system's age in terms of Earthly years.
