Imagine an entire civilization based on the Kardashians! A world filled with whinny fat assed attention whores. Is there some way we could avoid contact with these interstellar cunts?

Fucking. Kill. Me. Now.

I like your hottie or nottie thread more I think.

You ever fucked a space *****? No? So you are in no position to judge which thread you like more asshole.

One thing I found lacking.... what is it about the signal that makes them think it is from an alien civilization?

They did not seem to delve into this part of it very much.... if they have had it for over a year you would think they could tell us why they believe it is a signal from an intelligent alien civilization.

That was a terrible article. This one from SETI itself is a bit more technical but gives you the details and explains why it's also unlikely to be an alien signal. There is a youtube video where the it says the Russians said it was a military signal.

The fact is only the Russian team observed it back in May 2015 and no one has been able to independently confirm the signal nor has the Russian team identified the signal again.

I get where they are going with their theorizing, it is just a bit soon.... we just found the signal and have no solid proof it is from an intelligent source.... yet they are jumping ahead like "I BET THEY HAVE SPACE CARS!" lol

(1) They decide to broadcast in all directions. Then the required power is 1020 watts, or 100 billion billion watts. That’s hundreds of times more energy than all the sunlight falling on Earth, and would obviously require power sources far beyond any we have.

(2) They aim their transmission at us. This will reduce the power requirement, but even if they are using an antenna the size of the 1000-foot Arecibo instrument, they would still need to wield more than a trillion watts, which is comparable to the total energy consumption of all humankind.


The simple logic here is the energy emitted by the signal under the two scenarios if we assume the signal is real is an order so far beyond what we are capable of that it is unlikely to be produced by a civilization that isn't globalized.

This is literally energy of an entire star being used not to provide for the energy needs of the planet but rather to engage in an exercise that is essentially pissing in the wind in the hopes that some random civilization in an near infinite universe identifies it. You likely can't waste that kind of resource on such a frivolous exercise if your planet has various civilizations competing for resources.

If the US could harness the power of all the sunlight that falls to earth and used it for this, you'd probably have other countries ready to go to war over such a waste. You would literally be stealing sunlight from the rest of the countries and beaming it into space. You can only do this if you've got an overabundance of energy and a level of cooperation that far surpasses anything that has ever existed on earth.

That's part of the reason why the SETI dudes outside of this Russian team was so skeptical.

Trust me I get how they are coming to their conclusions.

But they are building on the assumption the signal is from an intelligent alien civilization, then they are making assumptions on how the signal is being sent as illustrated in 1 and 2 in your post, then they assume based on the ability to do 1 or 2 what kind of technology this alien civilization has assuming of course they have technology similar to ours, and finally they assume this is a globalized civilization based on 3 preceding assumptions none of which they have any kind of solid foundation for.

I understand their chain of logic.... but maybe hold off on guessing what kind of society they have until you can prove the signal isn't just backwash from a military satellite?

We should be careful who we talk to out there.
It might not be some cute little ET mother ******* who roll up on us.

Keep in mind our theory behind looking for signals is that other civilizations will be blasting stuff out into the cosmos similar to what we do naturally with all our technology.... we might be alerting alien civilizations to our presence without trying to do it intentionally.

Aliens might pick up on a signal that has an episode of Keeping up with the Kardashians and come murder us for subjecting them to that kind of nonsense.

Here is another theory.

This civilization is so scientifically advanced that their version of a AA battery has the power of one billion suns. This signal is being broadcast by a 12 year old from his hand held transmitter while he is playing in his backyard. It's not really an entire civilization working together in harmony, their word leaders spend more time bickering and going to war than ours.

Nah we can assume based on our assumption about the signal and how it was broadcast that our assumption that they are assumed to be a globally unified race of super-intelligent beings who built a giant metal ball around their Sun is correct.

Now let's move on to guessing what kind of food they eat and how fast their space cars go!

I read the article. Sounds like they need to justify the paychecks coming in. 2nd or 3rd paragraph they say it needs to be monitored permamently. Hmmm....how many paychecks will that take?

I assume based on their sun covering tech they have a keen fashion sense and enjoy pastels.

You should create a scale. "Ares Type XX civilization" because based on the signal we know that they are advanced enough to eat Space Rocks and use Interstellar gas to fuel their mode of transportation.

My point is you are conflating two separate issues. Regardless of whether they observed a signal or not, people have theorized based on the energy required what type of civilizations could produce certain signals. Those theories are not based on whether said signal has been observed in reality but rather based on as the name suggests a theoretical framework. So the theory predates any actual observation.

That is in many respects how science works. People come up with theories often times before something has actually been observed so your argument here would be like someone getting upset because Einstein offered a theory that predicted the existence of the black hole prior to any actual observation or evidence that one should exist.

You remove the element of people theorizing about things prior to their actually being observed evidence of said thing and science would grind to a halt.

Yes and in science some theories are more statistically probable than others and so that is the prevailing theory that governs. Sure I suppose your scenario is possible just like it's possible our universe was created by a Space God.

In the end, I would value your theory about this kid's battery just as much as I would value brett's theory about his Space God because there is really no scientific basis for me to regard your theory as more plausible than the one most people that study and look for alien life have argued for.

But you are free to have faith in your theory bro.

I do agree with Brett on the whole God thing so maybe I should keep my science theories to myself. As far as a space god, I am more of a Space Ghost guy.

Fair enough. Just saying there is a difference between theories supported by credible people within the scientific community and theories based more on faith. Now when the 12 year with a battery garners serious attention in the scientific community then I'll be right there nominating you for the Nobel Prize in Astronomy.

Jesus, you are getting super reductionist in here. Kind of surprised this is coming from you to be honest.

I get it, but my point stands.... hold off on spewing your theories about their technology or society until you can confirm an actual signal from an alien civilization.

Otherwise all you are doing is spewing guesses like an asshole.

OMG if this signal is real, and if it is omni-directional with this level of power, and if they are powering it by harnessing the power of their Sun, then they must have a technology of level X and a society with parameters A, B, and C.

That is a lot of IFs without you having confirmed shit.

I don't disagree with the theoretical exercise by any means, but applying it in practice when you have no basis to be applying it is misleading and stupid IMO.
