Everyone always goes "LOL advanced aliens are out there, and they're no answering because we'retoo primitive/not advanced enough/we can understand thier signals yet/they're waiting for us to advance. Anyone ever consider, that, maybe, perhaps humans are one of the most advanced species in the universe? ya, unlikely, but possible. And if so, rather cool.



Thoughts on the matter?

Cool twist on things.

Unfortunately I rather doubt it though. If the universe is as old as they estimate it to be then life out there should have a heads up on us because they have had more time to develop than we have.

we all like to think we are the best of the universe.

but i think the signals are baby talk to them. its more like "how do we degrade our machinese to suit those babies talk"?!?!

Do you have any idea how insanely huge the universe is?

Some of the first public radio transmissions began in 1920, meaning those radio waves are only 85 LY away right now, now remember that the Milky Way is up to ~100,000 LY in diameter.

Plus, however long it takes for a radio wave to travel to any given point, it'll take just as long for a reply to reach us again. Meaning in 1980, hypothetically, aliens could have recieved one of our signals that was broadcast in 1950, but we still wouldn't get their reply for another 4 years.

You'll have to give it a few hundred thousand years before you can realistically say it's not working.

Do these radio waves travel in any specific direction? Or just emitte in every direction?

When it comes to intelligent life in the universe, there is absolutely no reason to believe that humans are not the first. Someone had to be, after all.

Radio waves are extremely similar to Light (they're both part of the Electromagnetic Spectrum), they behave in pretty much the same way.

Radio waves are naturally emitted in all directions (like the light from a candle flame), or they can be focused using a dish (like the light from a torch).

Cool, so theoretically, we're hitting all the possible directions of where life could be thriving.

Only within a 50 odd light year radius.

I have proof that we are being visited. No one can deny this because its on tape. Lets see you de-bunkers get out of this one. These are the best ufos i have ever seen.

That's all the proof I need.

We could be the most advanced, agreed, but highly unlikely although I guess one species have to be

I honestly think the explanation for why we haven't heard anything yet is much more mundane. We ran over it in detail in how did they find us thread and please allow me to link to myself

All in all, no matter for how long your species have been in existence and have been blasting radio waves into space, there is a limit for how far away you can detect said radio waves unless you tap directly into a sun and really crank up the volume

I still feel that if they are far more advanced than us, then they will have ways to know where we are, esp if it goes into the thousands

Indeed, maybe thay are tapping into the fabric of space and doing something fancy. However, that doesn't change the fact the we are not doing anything fancy and are only emitting radio waves

The next option is that they have detected the planet Earth and that they can tell that something is alive due to the composition of the air. But my bet would be that is the best they can do and that they would actually have to come see for themselves whether Earth actually harbors intelligent life. Uhm, not sure if they would have reached a conclusion after having been here to see us

Nonetheless, this thread I guess was specifically on SETI.

From what is known of chemistry, the odds against a single peptide chain ever assembling itself at random seem superastronomical. That means the odds seem to be against life ever arising spontaneously in even one place, ever, in the entire universe, much less two places, much less two places close together at the same time.

This fact has led some to speculate that we are, in fact, a spectacular accident and probably alone in the universe.

It has led others to speculate that there is something we don't know which increases the likelihood that life will arise. I'd put my money on this explanation, if only because I like it.

But the truth is that no human being alive really knows the first thing about how life first arose here on Earth. Science has a good grip on evolution by natural selection, but genesis remains a mystery. So no one can calculate the odds of life-- much less sentient life-- arising anywhere else. That famous Drake equation? You can throw it out, because it's pure guesswork.

Again, I have a feeling that the universe is teeming with life, but whether or not that's true remains to be seen.

Not saying we are the ONLY ones in the universe, but it would be a hoot if we turned out to be the most advance Civ. Lol

Two words.
WOW! Signal.

That's the only thing, ever, that gives me reason to believe in SETI's project. However, the WOW! could have simply been a rebound of an earth transmission, although unlikely.
Where the WOW! came from, no one knows.

I think it's more likely that the Wow! Signal was deflected from Earth, or even natural phenomena. If it were extra-terrestrials, would they really only transmit one signal?

It's interesting to say the least.

This is, of course, assuming that other "intelligent" life forms have the same level of technology that we do. Hazzard mentioned the possibility of using the Entanglement Theory as a way of setting up communication networks throughout the galaxy. Perhaps the world that we live on is made up of orginial matter that is shared from as early on as the "big bang" or whatever started us outwards. If that were the case, and an alien race understood Entanglement as a siencetific practice rather than a theory, it is possible that they have computers that can match up any matter on their planet to see where it's connections lead to, and possibly effect matter elsewhere. It would be similar to remotely controlling a robot through a virtual reality program. If electrons on our planet share a relationship with every other electron in the universe, learning to manipulate their relationship to analyze data from other worlds would not be too ludicrous of an idea.

That is a very good assumption and in my point of view, probably the best means to realize FTL communications. However, the idea that ET can use this technology to listen in on us has two major flaws as I see it:

1) You can't just grab a photon and then looks at it's behaviour. You have no idea whether any given photon is quantum entangled with another photon, and if it was, where it's partner would be. Basically you have to make the entangled pair and then keep one for yourself while you send the other on it's way (at the speed of light).

2) You would be hard pressed to gauge anything on a macroscopic level from your photon unless you have it in a listening device that translates our radio waves or whatever you are looking at into oscillations at the photon's level. This can then be registered instantaneously by the "receiver photon" and analyzed.

Consequently, for quantum entanglement communications to work you have to make the entangled photon pair, stuff one of the photons into a listening/coding device and transport said device here to listen in on us (however long that takes us). And then you can gobble up all you want in real time. But who knows, my some ancient civilizations have sent out millions of probes that carry such equipment and right now we have a one lurking somewhere in our own solar system

again, i believe in life out there. out of 70 thousand million million million stars and counting, life should have happened again since the universe has laws built into it, which makes life in space, not on earth. but the reason why i dont think seti is going to succeed is because it looks for aliens that are too much like us. what if technology is a freak accident that occured only to one species out of all species in the universe. it could just be bacteria, plants and fauna, but unlikely to be any smart aliens.

honestly, i think theres ten thousand habitable stars MAX in the galaxy, bc its mainly unhabitable

While the Wow signal is interesting, it could unfortunately have a great many origins. I guess it could be from ET; we might not have been deliberately targeted, but by sheer luck SETI was listening when ET did a test, was aiming his dish antenna or something else. Or it could have been a freak atmospheric condition. Admittedly, I don't want to give an opinion on this matter as it is way up in the air.

Acouple different things i have heard..

1) They are technologicly more advanced then us, But lack emotion, sorrow , and other human charecteristics. its also said that they have no soul and are fascinated that we do. They study are feelings...I dunno, heard it a few times..

2) SETI is a cover up to lead the public on that we have not yet discoverd alien life when in actuality we have been in contact with ET LIFE since after WWII...

I buy #2 maybe #1

Technology comes with intelligence; I don't believe that intelligence just occured by accident, it's favoured for by evolution. Then again, some people theorize that our ancestors took an intellectual leap through consuming hallucinogens. So who knows.




You're right, although it's fun just to speculate.




...yet there's no reason to believe either.

It's also said that aliens could be using a Neutrino Communication system, rather than radiowave transmissions; and that's why we haven't detected anything substantial yet.

I doubt it. Neutrinos travel more slowly than EM radiation and would take even longer to carry messages. My guess is that some form of instantaneous signal is possible, perhaps using quantum non-locality.

plus the who knows how many other galaxies big and small are out there
