SENDING messages into deep space could be the best way for Earthlings to find extraterrestrial intelligence, but it carries a grave risk: alerting hostile aliens to our presence. Game theory may provide a way to navigate this dilemma.
So far the search for extraterrestrial intelligence (SETI) has mostly been restricted to listening for signs of technology elsewhere. Only a few attempts have been made to broadcast messages towards distant stars. Many scientists are against such active SETI for fear of revealing our presence. If all aliens feel the same way then no one will be broadcasting, and the chance of detecting each other is limited.
To weigh up the potential losses and gains, Harold de Vladar of the Institute of Science and Technology Austria in Klosterneuburg turned to the prisoners dilemma, a game-theory problem in which two prisoners choose between admitting their shared crime or keeping quiet, with different sentences depending on what they say. An individual prisoner gets off scot free if they rat on a partner who remains silent, with the silent partner getting a maximum sentence. If they both rat on each other, each gets a medium sentence. By contrast, if both stay silent, both get token sentences the best overall result.
De Vladar reasoned that the SETI dilemma is essentially the same, but reversed. Mutual silence for prisoners is equivalent to mutual broadcasting for aliens, giving the best results for both civilisations. And while a selfish prisoner rats, a selfish civilisation is silent, waiting for someone else to take the risk of waving Over here! at the rest of the universe.

Theyve very likely been traveling this way for billions of years. People simply do no comprehend the vastness of space.
I will do that, sir. If ever we find something out there that isnt an airless rock, will want to know all about it.
I dont see the dilemma myself. I dont see a danger in letting aliens know that we exist. Any alien civilization with the technology to attack us across the vastness of the universe probably already knows we are here.

If they were that advanced, and with the shear size of the universe it is probable; they would have no reason to make us aware of their presence. If anything, in our primitive state, we would be nothing but a danger. Our planet is likely quarantined for their own safety.
Nice
Like many other ufo incidents, the tale grew in the telling.
Many years ago I read an article in Scientific American. The article proposed a trip to Alpha Centauri, the closest star. The author calculated that if we could get a spaceship that would accelerate to maybe 15% of the speed of light, then it would take roughly 50 years to get there. When it arrived it would be going so fast that you would not be able to slow it down. Youd zip thru the star system in just a few hours. Then the author talked about what that spaceship might look like. He proposed a massive balloon made of aluminum that was filled with hydrogen to fuel a nuclear powered rocket engine. He assumed wed invent the technology. When he said massive he meant about 10 miles in diameter. The payload of this rocket would be a camera. There would be no capacity to carry anything more.
There always is THIS explanation for extraterrestrials...
Anyone who searches for a image of the Phoenix Lights is going to find only those of the flares which were dropped later.
But there is cell phone video of the actual lights as they flew over. Saw it one time on one of those investigation shows, but have never been able to find it since.
Bkmrk.
then you should look up all the planets found in other solar systems: water worlds and so forth. More are constantly being discovered especially now that the JWT is online

Strong possibility.
In the old days if you wanted to cross the US you used a covered wagon driven by horses.
(fast forward to some future date)
In the old days if you wanted to cross space you used a spaceship with a rocket engine.
(Clearly you will have to be able to bend space-time to go any distance at all—that technology is not available yet, and may not be for a while—but any advanced alien civilization would have to have it—and that would mean that the vast distances of space would be irrelevant.)
At the speed of light, the closest star to Earth is 8 minutes & 20 seconds away.
“Babylon 5” actually had an episode on this. The probe carried a bomb and said answer all my questions or else I explode. It had very difficult questions they barely answered. The Captain realized that the probe was sent to DESTROY potential threats. That any aliens that COULD answer the questions and were advanced were to be wiped out by the bomb.
