It wasn't SETI who sent out. I think it was a UN or a US initiative. In any event, the hyper extraordinary energy required to travel and communicate between stars is highly unlikely to have arisen from a combative rather than a collaborative enterprise, so I would suggest that any advanced civilization which choses to contact us is about 90% more interested in assisting us than eating us, though more like 95% more interested in ignoring us.

The "Wow!" signal is exactly what should be expected when both sender and receiver are on rotating planets in star systems that are moving at terrific speeds. You'd probably get a brief signal that didn't repeat because you'd rapidly move out of alignment and the signal would no longer be directed toward you.

In the movie Contact 1997, Jodie Foster intercepted and decoded an alien message that gave us the plan on how to build a time travel machine. The technical plans in the message was encoded in the track between each frame of video. So the government built one (two actually). And Jodie went somewhere and talked to the "alien. Great movie! What if we encode a message in laser beam pulses, like a morse code with short and long blank spaces between each laser "chunk". That would "identify" them as artificial light. Then the message can travel at the speed of light. Then, broadcast the laser message beams from points of the globe to cover the whole universe. Then wait for the "reply"..

WELL ... how capable would some of those intelligent beings be by now THEN !? I think we all need to face the fact that what we don't know or understand yet, is why THEY DO NOT WANT US TO KNOW THEY'RE THERE ! Or why they may have to wait for us to confirm to ourselves that they are there, or reach some phase of development, and that they have always been there even before we were here, waiting for us to realize that without needing to prove it. In other words, a 180 degree turn around from how we think of it today. There's nothing to discover or prove. We are either their plan, their intention, their monitoring, their offshoot, their children, their workhorse, their thing they do or created for whatever reason... we just don't know. They're either watching, or waiting, or using us, or raising us, but what we do know is that the situation is reversed to how we are thinking about it. None of these guys factor in the exponential acceleration of intelligent material and communicative progress ! It's unbelievable .

An article in the September 2018 Scientific American makes a compelling argument for the conclusion that we're probably alone in this galaxy. For example, we have a n unusually powerful Van Allen belt and a truly unsual big Moon--the the result of a collision between Earth and a Mars-sized planet over 4B years ago. That collision gave us a thinner crus--which became the Moon---and a thicker Iron/niickel core; toghether those enable plate terctonics, stabilize Earth on its polar axis, prevents space radiation from sterilizing our planetary surface and from the surface getting weather too violent for advanced life to exist. Plus the discovery and mapping over 320 planets in nearby solar systems shows that our configuration is unique among them, further lowering the likelihood of an Earthlike planet out there. I'd love the galazy to be full of intelligent life, but it's becoming clear that we understimated how unusual Earth is. Too bad we're destroying it, because thrre's no Plan B out there.

Its moon is like our moon very big. So for 2 planets dwarf or what not in 1 solar system to have that probably suggest that the big moon is much more common then you think. your whole thing revolves around the Moon being rare.

Uh, we don't understand how self-replicating molecules form, but we're pretty sure it's common throughout the Universe? Wouldn't it be more accurate to say we don't understand how self-replicating molecules form and so we have no idea how common life is throughout the Universe? We don't know! While it might be true that life originated early in this planet's history, our current understanding is that all life on Earth originated from a single source. That means, regardless of when life here originated, it didn't do it any other time. And since most of us would consider Earth to be an ideal environment for life, that fact that life only originated once here would seem to contradict the assumption that it is a common event. The fact is, we don't understand how life originates, and we can say nothing about how likely it is to originate beyond the fact that we know it's possible. And when you combine that with the fact that, whether you're talking about exploring other planets or the SETI program, we've yet to find a shred of evidence for alien life, life in the Universe might indeed be very rare.

When indeed. Consider that we have had radio for about a century at this point. If we continue to use radio in this way for a thousand years, that's a problem. If there are about a million worlds that are somewhat close to us and visible in our galaxy that have once used radio as we do now, that would mean, over the last few billion years, they would have given off a pretty clear signal of it. You see, we here on Earth are many times brighter than the sun in these specific radio wavelengths. In fact, we stick out like a sore thumb when one switches between regular visible light and radio light. First, if we assume that radio is the be all and end all of long distance communication, then, if there were even just thousands of civilizations in the nearby part of the galaxy, still using radio presently, we should see plenty of them out there. But we don't. So eventually civilizations replace radio, or dies trying. But how long do they last with radio? So let us assume that there is some combination of how many radio civilizations there are in the nearby part of our galaxy, at any one time, and also assume, on the average, how long they stay with radio, also on the average, in order that over the last few decades, we haven't seen the evidence of them, despite looking. Let us assume that for the last 4 billion years there has been the opportunity for a civilization to arrive at radio. That's a fair amount of time after the galaxy formed, about 8 billion years, give or take a billion. The fractions are within a single order of magnitude, so we can work with that. At 4 billion years, at 10 million civilizations, on average that means that the limit is that every 400 years on average a new one appears locally. Let's say that we've been watching for 100 years. Under these assumptions, we could watch for an average of 300 more years before detecting another one of us just starting. However, if they hold on to radio for 1,000 years, we should see at least 1 or more of them at this time anyway. So, locally, there should be less than 10 million such civilizations, and they should last with radio for less about 1,000 years each, on average. Otherwise, that's 10 billion radio years in 4 billion galaxy years. They should be easily found around us. So that's a kind of limit on these two variables. However, for instance, if there were only about 1 million such civilizations, out of the billions or so suns in our galaxy, that would mean a new one appears every 4,000 years. Even if they last for 1,000 years, that would mean a long enough, on the average, wait in between them so that we wouldn't see them if we looked for say 100 years. Or there could be 10 million or so such civilizations, each holding on to radio for slightly more than 100 years. That would do it too, on the average, but not for 100 years of searching, unless we were particularly lucky, or unlucky, depending. What this means is that, since we don't see many neighbors with our obvious pattern of visibility in visible and radio wavelengths, one of 2 things is true. Either being a civilization with radio spells doom for it within a short period of time, much less than 1,000 years, or they are smart enough to graduate to something else, and become effectively radio dark within a fairly short period of time after the first 100 years, or so. I pray that it's the latter. If so, however, then that establishes a different problem. What replaces radio? Is it some kind of sub-space radio, that takes advantage of the 4 dimensional sub-space that we are really in, as a 3 dimensional surface universe? When do we start to properly investigate hyperspace so that we can find this novel form of communication? Perhaps we must find a new model of the standard model of particles that explains dark matter as a 4th, and above, dimensional model of this invisible matter and energy. Do we have a 3-ball model for matter? Yes, we do. It's called the TRIMOBIUS(R), and was patented under US Patent 4,138,744. Go figure. Let's start an investigation right away.

Donald Trump tweet. and Referring to North Korea’s volatile leader, Kim Jong-un, Mr. Trump said, “He has been very threatening beyond a normal state, and as I said, they will be met with fire and fury, and frankly power the likes of which this world has never seen before.” Where have you been?

[@blaster-zy7xx]

Alexander Anderson Oh my God, it is so obvious that you think Fox News is News. It isn't. Fox News is right wing propaganda 24/7. 1) North Korea is not abandoning it's nuclear weapons program. That was reiterated by Kim Jong-un within the last week or so. 2) What North Korea destroyed for the cameras was a nuclear test faculty that was heavily damaged in their last nuclear test explosions. That was NOT their development facility. 3) Get off of Fox News and read what is going on from independent sources like the BBC, The Economist, NYT and others.

There is an uncountable amount of stars(suns) on the univers, which has orbiting planets like ours. to think non of these planets host life is simple unthinkable. Furthermore, if life is out there, the most likely scenario is that they are either millions of years in front of us or behind us on an evolutionary state and therefore also technological state. Therefore there is a high chance that we are already being visited or have been visited.
