And you won't be surprised what we're sending.

Not sure if this has been posted, I'm not sure if this is the right section, but this is newsworthy anyway.

Ugh, now other life forms can now know how we behave. Youtube Comments, Yahoo! News, now this. Bleh.

we've been sending all sorts of crap in space since the inception of the radio and television..

but experts in radio frequency wave propagation, say that it is highly probable that the uncorrelated collective of radio waves dissipated beyond a usably robust signal strength roughly one light year away from our sun. so even though we've been sending out intentional EMF for roughly a century, only a fraction of that has made it much past the oort cloud.

This planet has been lit up like a neon light since about the time humans started fooling around with electromagnets. I would place that around 1800 when the wet cell was invented.

It does not really compare with what a star or quasar puts out though.

No, but a sufficiently sophisticated amplifier can pick up our feeble outputs.

Humans have been electromagnetic transmitters since we figured out how to make electric current.

Wouldn't these transmissions be disrupted unless directed, like in the article?

If there are other intelligent forms out there, why haven't we heard anything?

Our major signal is the 60 cycle hum from transmission lines, that have a loss up to 25%.

That has reached out about 100 light years, which is not far on universe scale.

It is not natural, it would stand out, but a reply in 60 cycle hum would take another hundred years to come. We would miss it.

All of our radio and television has short range.

It is huge, a million technological civilizations in the Galexy, would be hundreds of light years apart.

Then there is the so what factor, if we picked up an intelligent signal from 200 light years away. Sending a reply takes 200 years each way, so wait at the phone for 400 years. Going there would be expensive, take several thousand years, and they might be just like us, making it a wasted trip, except our germs would likely kill them all.

Then there is The Galactic History we do not know, prior contacts between civilizations, leading to the death of worlds, where the reasonable reply to a signal would be a planet smashing weapon, which would take another hundred years to get here.

A historic accident killed the Reptiles that should have been top species, and of the mammals, apes are the worst. Taking that it could have happened hundreds of times, there could be a fund set up for Apeicide.

We smelly apes are close to making a world where machines design and build machines, so it is likely there would be others who did the same. Machines would have a very different outlook on life.

As raw material for a machine world we could be rendered for lubricants.

We did it to the whales. Until recently? Automatic transmission fluid contained whale oil.

Also, at night, this planet is brightly lit just where the apes live. Targeting them would be easy.

Our survival is based on being alone in the universe.

As AuntBlabby said there is very little getting out.
100lo does not even reach across the arm of our galaxy.

Maybe obesity has been engineered for lubricants by the Illuminati? :lol:
I still don't think there is much useful on the average human for lubrication.

I think our survival probably depends on the ET's not wanting anything to do with us.

That might change if we bombard them with facebook updates and unsolicited tweets.

If there is Intelligent Life with advanced technology Out There most likely they cannot get to us for the same reason we cannot get to them. It is too damned far to go.

Unless there is a revolution in physics there is no empirically sound reason to believe that the speed of light is not top speed and that the Special Theory of Relativity is not correct. No one is going to be flying at or faster than light speed any time soon. And if some alien race did have the technology, why aren't they here?

If we could travel at the speed of light, there is nothing within a hundred years. Real Estate with near Earth gravity, liquid water, a Moon, Magnetic field, is scarce.

Building a robot probe would be hard, taking along a colony of apes would be near impossible. Perhaps some fresh frozen, to be raised by robots, and used to test the livability of another world.

No one has been concieved and born in space. Would they even develop bones? We might fake gravity, but inertia? At one G out, and one G to slow down, it would be a much longer trip.

Moving Venus into a counter Earth orbit, putting something big between it and the Sun, wait 500 years, would be cheaper and faster.

The cheapest is to rebuild Earth, it is rundown, but it could be a restored classic. Turning all the deserts into forests would be easy.

I think Automatic Transmission Fluid contained Whale Oil until the '70s.

I wonder if our technology [if magically transported out past the oort cloud] would be sensitive enough to tease out usable signals amidst the cacophony of uncorrelated earth-civilization-sourced radio waves?

Thats not my understanding of how it works.

The ort cloud does not stop radio signals ( like the way our planet's atmosphere stops certain cosmic rays, and certain wavelengths of light).

Its just a milestone marker.

We dont need a radio telescope version of the Hubble to sit beyond the Oort Cloud (if thats what you're asking) like we do have the Hubble light telescope in near space above our atmosphere.

Our radio signals have reached 100 light years out, and our TV signals have reached about 70 light years out. Star systems average about five or six light years apart. So weve hit hundreds of star systems with our media already. But the signals loose coherence and become random static at about two light years out - about half way to the next star- or about where the Oort Cloud is. Its the distance-not the Oort Cloud itsself- thats the problem. The radio waves just get too dissapated and out of sync to carry the information because of distance itsself.

So creatures seventy light years away are NOT experiencing Milton Berle's Gaslight Hour as we speak (no need to be embarassed as an Earthling). If said creatures exist they are only getting a mass of static on their recieving equipment that happens to be pointed our way. But its static in strengths and frequencies that would obviously be of non-natural origin. So they would indeed sit up and take notice of it as evidence of intelligent life even if they couldnt experience the content of our media programming.

So the same would be true for us as with them. On earth (or from near earth satellites hovering above our atmosphere) we could detect a civilization like ourselves out to a great distance. We would not be able "watch their TV shows" as such. But we could detect the mass of artificially produced static they produced (and would recognize it as artificial) out to many light years because of its frequencies and other characteristics.

The question I wonder is this: how far out could we detect ourselves? If there were a twin planet with a twin civilization to ours emitting the same amount radio noise- whats the greatest distance it could be for the big dish at Arecibo to detect it? Whats the max number of lightyears that we could detect a twin of ourselves out there?

Anyone have a guess?
