SETI Detects Alien Signal From Jupiter's Moon Ganymede

Postby chimaybliss » Wed Jan 19, 2011 6:12 pm

This is the best story I ever heard concerning contact with aliens. It is pretty humorous.....

NASA and SETI Astronomers detect an artificial alien radio signal originating from Ganymede, one of Jupiter’s largest moons. When did this happen? Believe it or not but this scenario is supposed to have taken place during the 1980’s

I think it is a "shaggy dog" story

this is what Rupert Matthews reports in his book......... NASA and SETI astronomers picked up on a radio signal ..... The signal was coming from Jupiter’s moon Ganymede and was definitely artificial in nature. The signal was run through multiple computers and no sense could be made as to the meaning of it......

So far, so good.....although I'm not sure if SETI was ever aimed at any moon in our solar system. ( Someone may have better information on this) and I'm not sure how out of space broadcasts are "fed" into decryption computers that need alpha-numerical input data ( Why would NASA assume the alien signal was not just a complex wave to perform some mechanised instruction rather than a "message". The first step in signals analysis is to determine if you are reviewing a "message", "data" or an "operation". )

Eventually it was decided to send a signal to the exact location that the message was coming from on Ganymede. This message would be sent in Morse Code which was considered to be the easiest for an alien civilization to decode.

Morse code is fine if you speak English. It seems an odd assumption that the aliens understand English considering 500 languages are broadcast over TV and radio everyday.

It would read “We have received your signal, but we do not understand it. Please resend your signal using this language and transmission code.” Immediately after this message was sent, the mysterious signal from Ganymede ceased its transmission so everyone assumed that we would receive a new signal in Morse Code in a quick period of time. But day after day and then week after week no signal came and officials began to give up hope of actually receiving a response. Finally after more than a month, a signal was detected coming from the original radio source on Ganymede and incredibly it was in Morse Code. Eagerly NASA scientists translated our first direct contact with an alien civilization. And it said “We were not talking to you.”

Now that's just rubbish. "Talking to you" ( as in open one's mouth in an oxygen environment and talk into someone's ear rather than "exchange electronic communication") Obviously this alien has uses human metaphor expressions, which suggests it is really some "wag" at NASA playing a practical joke.

I don't think anyone lives on the moon. If they were there they were visiting. Why would they stay for a month? What would they be doing on Jupiter's moon that would keep them occupied for a month?

That's an interesting answer for a couple reasons. We are all creatures from the planet earth. The speed at which our "earth-evolved" chemical processes take place and thus the speed that we perceive things is probably unique to earth. Because we share the same DNA as all other earth living things and we interact with them I propose that life on earth has a homogenous "speed"

However the aliens from planet "X" may have evolved with a different chemical system and life on their planet may have a very different perception speed to life on earth. When Richard said "What would they do on Jupiter's moon for a month" I think we have to consider that a month to "us" may be a "moment" to the aliens. ( This is why I don't think "Star Trek" simultaneous alien translators will ever be a reality. I will stand in from of the Green Blob from planet "X" and want to talk about earth yet it may be a year before the Green Blob says "Start communicating now" and this would seem natural to the Green Blob.

If that were true, then there would have not been enough time in the history of the universe for them to have reached a technological level of development.

Try again, Matthew.

Nahhhh. Even the beasties on earth live at different "speeds." For example, a television program would look like a very boring slide show to many creatures, or as a meaningless blur to others.

Well, I decided to do a science experiment of my own. After down loading Morse code, cranking up the Ham radio, and pointing the antenna toward Jupiter, I sent this message.

Yo alien dudes, whass up? You not talking to me buddy?

It only took about 20 minutes before I got a response, which if I decoded it right says.

Numan, the universe is 13 billion years old. Please explain in detail "your theory" that 13 billion years is not enough time for a slow alien to develop technology that humans have had for only 80,000 years.

I don't think you can do this. I think you have just opened your mouth again to seek attention. Can you find a witty quote from tyour beloved Oxford English book of popular quotations to answer this? No? Does your Stephen Hawking avatar hide your inability to do this? No? Can you do it using your own brain? No?

Matthew, I still hold the opinion that you are, upon occasion, capable of displaying intelligence. Please do not disappoint me.

It has taken 4.6 billion years for the planet Earth to produce a technological society (I can't call it a "civilization"), not 80,000 years. That is one-third the estimated age of the universe.

If a year of our time seemed to be a few seconds for the aliens, it would take many, many trillions of years for them to produce a technological society. Please engage your brain, Matthew.

I won't comment on the rest of your posting, since it is just your usual time-wasting argumenta ad hominem.

Even if a "slow" alien species did manage to reach a technological point which allowed interstellar space travel, it stands to reason that they would have sought technological ways to improve their biology so they could mentally keep up with a lowly bottom feeding dead plant burning species. Surely the theory of evolution also encourages all life forms, even alien species to compete physically, and therefore to have better and faster mental and physical abilities. I would imagine in a competitive ecosystem this bbettering occurs naturally, so most likely IMO any capable spacefaring alien species would be atleast as mentally quick as us, and possibly due to technology, can change it's mental faculties to meet a situation.

The age of the universe from the local space time of earth is ~ 14 billion years. That does not say from a different local space time, it is not much older, or younger, thus in other parts of the universe life have existed for much longer, say 50 billion years, and thus evolved more.

Time is relative, the whole universe does not revolve around us, or tick to our clock, only we do.

If you lived on earths moon, where gravity is ~ 1/6th that of earth, the universe is older. Exactly how much older, you can compute via gravitational time dilation, which is a real effect. i.e. the universe actually is older. The reason it actually is older is due to the fact that time is a dimension of space-time, which can be viewed as the most fundamental building block of existence. Change it, and you actually do change the reality of existence, not just a perception of change.

But isn't space expanding in the same way irregardless of what point in space an observer is? Rrichar911, Can you please provide some kind of reference to support your statement that the age of the universe may vary depending on location, otherewise we should assume the universe is roughly 14B years old throughout the universe.

http://en.wikipedia.org/wiki/Gravitatio ... e_dilation

Gravitational time dilation is the effect of time passing at different rates in regions of different gravitational potential; the lower the gravitational potential, the more slowly time passes


The universe would be the same age as it is on earth only to people who lived on a planet with the same gravitational potential as earth. A smaller planet and the universe is older, a heavier planet and the universe is younger.

Time dilation due to spacial expansion is a different effect from either time dilation in SR (special relativity) due to velocity, or gravitational time dilation in GR ( general relativity) due to gravity. They are all however real effects because they all involve changes in space-time, the changes are just for different reasons.

So Numan......
what was the level of technology on earth at 1 billion years?
what was the level of technology on earth at 2 billion years?
what was the level of technology on earth at 3 billion years?
what was the level of technology on earth at 4 billion years?
(Hint...there wasn't any technology 600,000 years ago. When did the neolithic period kick in?)


So Numan.....
Why would an alien green blob from another planet care about how old earth is?
(Hint.... the alien isn't from earth and could be from an older planet...you really need to think before posting)

I really don't think aliens will need to drive cars, watch TV and post on forums for me to try to communicate with them. You added your own "Star Trek" based knowledge in your own assumption. I can talk to homo sapiens 80,000 years ago as well as a modern homo sapiens. (Hint they are the same species regardless of their technological development level.) .

I'm still not convinced that technologically advanced alien races wouldn't be humanoid, to some degree. We know that the opposable thumb and gift of speech is what gave us the advantage over other species on Earth. Bigger brains and walking upright paid off, but were quite the gamble. I'm not sure that advanced sentient life on another planet wouldn't have similar evolutionary requirements.

That is a well-known, hypothetical speculation----completely without observational confirmation.

Well I don't really know either. ( and proud to admit it!)

It would seem reasonable to me that some aliens will come from liquid or thicker based atmosphere environments. In that case walking upright would be a real disadvantage. I also imagine that some alien environments will have heavier or lighter gravity and therefore multiple legs may be the evolutionary advantage.

In the liquid environment there will be no ability to communicate by "talking through the air", so some other communication system may flourish. Perhaps the green blob aliens from "Waterworld" have to touch each other to communicate. Perhaps the flying flashing stingray aliens from "Low gravity & low light world" flash different colours from their flippers to warn their fellow aliens "dinner is ready"

I reckon when we are going to get some huge suprises when we first come across "aliens".

Well I don't really know either. ( and proud to admit it!)

It would seem reasonable to me that some aliens will come from liquid or thicker based atmosphere environments. In that case walking upright would be a real disadvantage. I also imagine that some alien environments will have heavier or lighter gravity and therefore multiple legs may be the evolutionary advantage.

In the liquid environment there will be no ability to communicate by "talking through the air", so some other communication system may flourish. Perhaps the green blob aliens from "Waterworld" have to touch each other to communicate. Perhaps the flying flashing stingray aliens from "Low gravity & low light world" flash different colours from their flippers to warn their fellow aliens "dinner is ready"

I reckon when we are going to get some huge suprises when we first come across "aliens".


I hear you, and have the imagination for it. But I'm having trouble with the idea of, say a blob, or stingray type being having the ability to use tools effectively, which I think would be fairly important. Let's face it, a brilliant mind in an ineffective body can't go very far without the assistance of someone that's handy with tools, and can produce the vision into reality. So even if the dominant being is a blob, they have to have another evolved creature that has some appendages, and the cognitive ability to use them effectively. This doesn't mean that sentient life has to be a tool wielding species, but to be technologically advanced, I'd think it would be a necessity.

That is a well-known, hypothetical speculation----completely without observational confirmation.

Of course, it's hard to leap out of my own experience of how things work.

I think we have to be careful with the word "tools". The dolphin like creature with many arms from "Flipper world" may have a different range of hydraulic tools, water pressure tools, etc than we could have ever considered on earth. ( OK I'm not sure how they would invent "fire" but I'm not sure how a earthling caveman would invent "water pressure cooking" which may be normal on "Flipper-World"). I think any life form would have its unique way of developing/evolving its technology, due to it's environment and would end up with a different "final technology"

Therefore the fat, self inflating, many armed, hydrogen filled blobs of "Float-world" would be saying "Those stupid humans for earth, how could they use proper tools if they cannot even fly" and saying so on the Floating Blob Skeptics Forum (Moderator Blobpyrrho

Well light doesn't travel through space instantly, so I doubt sound does. It could have taken a month for the message to get to Ganymede and then the reply to get back.
