Extra-Terrestrial Megastructures detected around a star?

I have been searching for anything which would clarify Brian Cox's statement that we are the only civilization in this galaxy. So far, all i've found is something about a lack of alien artifacts (if this dyson sphere claim were true, that would shoot that in the ass), and the improbability of our own existence. But all i've found so are is stuff by journalists. That's never very reliable sources.

Any wouldn't that be something. It's a line of thought most people never take, but it's certainly not impossible.

We might be the first to step onto the galactic stage, and in 10 million years end up being the elder statesmen of the supercluster, who knows. Although I doubt there would be much left which is human about us after even a hundred thousand years, much less millions.

I think I'll use it as the premise of my first sci-fi novel! Smile

Now will be the wolf or the shepherd?

I completely agree with your last sentence.

@Setanta,

remember that the term for civilization classes and "Dyson Spheres" are all kokamamie assertions by "futurist" type thinking.

For all we know the harvesting of energy for a really advanced civilization may be like a creation of a microwave "tractor" or the mass production of matter/anti matter.
Dyson chains and speheres are kind of a way that WE may consider harvesting energy.

For the last week, Vakoch and his colleagues at the Search for Extraterrestrial Intelligence (SETI) Institute have been pointing the ground-based Allen Telescope Array in California at the enigmatic star with one goal in mind.

“We’re trying to rule out the hypothesis that maybe it’s intelligence out there,” Vakoch told Business Insider.

He added that they’re crunching the data in real-time and will, therefore, know if it’s ET within the next week, or so.

@FBM,

next thurs a scientist involved in the seti activity wrt this star, will be on the radio on one of those mufon stations

I had to look up Mufon. I don't expect it to turn out to be ET, but if it did, I'd be thrilled shitless.

@FBM,

If you want to listen, youd have to stream some station that carries a radio show called "Coast to Coast AM".. Its a show that's big into conspiracies, ID/Creationsim, Fringe SCience, and ABO (anything bit Obama)

Heh heh. I think I'll just wait for the headlines. I don't think I could sit through a broadcast by tinfoil hatters, even if the guest is a SETI scientist.

We'll have to hold our breath for a bit longer than that however, because...

Vakoch expects that observations will end Friday, Oct. 23 at which point they’ll immediately begin writing up their results and put them through the coveted peer-review process that is the backbone of any reputable scientific discovery. More importantly, this means that if the scientists have found something, then they already know. But they won’t be saying anything for at least a few weeks.

“So you can expect it to be several weeks or months until you here the conclusions of our observations, even though we may be wrapping them up in the next week or so,” Vakoch said.

@FBM,

just for grins, do a google link with WHP 580AM.(Its Harrisburg Pa's right wing talk station except for the night time when the entire network sounds like gungsnake) They have a streaming component and its good quality . no jumps or pauses. (Course, a lot of that is my ISP)

Hmm. I tried about 10 different links, but nothing works. One message was in Korean. It said something like 'This content is not available from your location.' Sad

i hope their Dyson Sphere is less annoying than those Dyson hand dryers

@FBM,

oy, I got my first "Unavailable content" notice from some site that Dlowan had posted and I was blocked. I felt pissed.

Weird rules we all seem to have. You probably have faster internet than we . US is a joke for "high speed".
When I was last up in New Brunswick (Canada , not New Jersey), the wifi was rippin.

If there's one thing I can testify to about Korea is that the broadband is out of this world. I down...get movies at over 5MB/s. Very Happy

On the other hand, censorship. Evil or Very Mad

Keep in mind the speed of light. It is unlikely that this particular speed limit can be broken.

Humanity could in theory populate the galaxy (time dilation would make the trip bearable for the colonists, although it would be a one-way trip).

But without frequent contact between star systems for people to intermarry and exchange DNA between groups, the population of each star system would evolve on its own independent course, and we would very quickly (as geologists measure time at least) evolve into a bunch of different species.

I'm not sure why they think they will soon know definitively.

If they pick up video of something with tentacles delivering a news broadcast, then maybe that will prove that it is definitively alien.

But if they don't pick up anything unusual, that might mean there are no aliens there. Or it might mean that the aliens are communicating in some fashion that we are unable to intercept.

I suppose if they definitively prove that this is being caused by a huge barrage of comets around the star, that would disprove aliens. But are they going to be able to do that with a radio telescope?

It could be both. Note what I said two posts up about becoming different species.

Presumably in this sort of Sci-Fi novel you will have to make the speed of light something that can be exceeded. However maybe humanity went to the stars before discovering faster-than-light travel, and in doing so diverged into different species.

And maybe one group of human descendants decided that they should become galactic Nazis, while the other groups of human descendants do what they can to oppose them.

This may be a case of the Media looking to create a headline when there's really not much to say. So maybe the headline should have simply said, "Universe projected to last 100Trillion years, which means we're only about 8% of the way there". fizzle.

While it is true that the universe will not be forming habitable planets after the age of 100 trillion years (that is the time that the last of the longest-lived stars will burn out and plunge the universe into darkness), note that this does not mean that everything comes to an end at this time.

If I were an intelligent being around the time that the last star in the universe burned out, I'd not be thinking "Well, we had a good run, time to lay down and go extinct."

I'd be thinking "Well, our Dyson Sphere won't do us much good anymore, so let's go find some gas giants, mine them for hydrogen, and fire up some fusion reactors."

Depending on how fast we consumed the fuel, there should be enough fusion fuel in all the galaxy's gas giants to last us a very long time (and we could mine the galaxy's asteroids/terrestrial planets for fission fuel as well). We might want to consider stepping back down to a Class I civilization though, in order to make the fuel last as long as possible.

The real obstacle to the continuation of life will not be when the last of the stars go out in 10^14 years, but when matter starts breaking down into subatomic particles in 10^33 years. As beings composed of matter, we'll have trouble existing in a universe where matter no longer exists.

@oralloy,

when that occurs it will end in a huge gamma burst. SOunds like finis .

The question has not been suitably answered whether the field consists pf Multiverses which meet at the edge of their membranes. we would be dealing in gigaparsecs in distances

The breakdown of matter will not be rapid. Protons are alleged to have a half life of 10^33 years.

By 10^34 years, 10 half lives will have elapsed. By 10^35 years, 100 half lives will have passed. Matter should be much less common in the universe by that point.

However, if the universe ends in a Vacuum Metastability Disaster, there will be a lot of energy given off in that case.

We need to assess whether or not we are part of someone's computer simulation before we go about trying to jump from universe to universe.
