SETI’s Colossus (Huge 77-meter infrared telescope)

Call it stupidity or ignorance, but I fail to see how emissions not directly aimed at something, projected to a very fine point with incredible power behind it, won’t simply fuzz out into nothingness in a short distance (relatively speaking). We communicate with our probes because the math was done on their trajectories, so we have a good idea of where they are in space. Also, since it seems the heliosphere is actually a circular, real-thing in space, how would extraneous emissions reach distant solar systems if they aren’t directed?

The Forbin Project?

The extraneous emissions from a planet reach us without being directed just as light from the star reaches us without being directed. The problem is it’s an extremely weak signal by the time it gets here. Thus the need for a giant telescope.

Our Planed transmits a 24 hour cycle of 50HZ-60Hz from our power lines that is ten times brighter than the sun in that spectrum. As the planet turns from North America (60Hz) to Europe (50Hz) the tone changes.

Kinda like a low frequency European siren, BeeeeBaaaaBeeeeBaaaa.

Kinda cool. It’s like a giant “come Nuke us” signal we have been sending to the stars for years.

Our “Planet”...

[LibWhacker]

That’s cool, thanks. Never thought of that.

[hoosierham]

Hopefully the time lag will mean that we will have the means to repel said nukes.

Improvements in communication facilitate centralized control.

The Forbin Project?

WE ARE COMING. DO NOT TOUCH COLOSSUS. WE ARE COMING. DO NOT TOUCH COLOSSUS.

Our Planed transmits a 24 hour cycle of 50HZ-60Hz from our power lines that is ten times brighter than the sun in that spectrum. As the planet turns from North America (60Hz) to Europe (50Hz) the tone changes.

That's interesting where it is possible aliens can detect us by the frequency used in our power mains. What's confusing is Japan, the northern part uses 50 cycle power and the southern half runs on 60 cycle. I think there is 25 cycle power still being used at Niagara Falls and some motors that drain water in New Orleans still use 25 cycle power as well.

[gfbtbb]

That was the best explanation I have seen yet.

[slouper]

What a colossal waste of time, effort and money. This makes me sick and I’m a scientist.

[wastedyears]

So so little as our power lines are traveling light years across space without being stopped by anything electromagnetic, like the heliosphere?

Thanks LibWhacker.

Cool.

I’ve always thought the assumption that sending signals to aliens would be a good thing extremely odd.

[Trod Upon]

I always wondered why people assumed an advanced extraterrestrial civilization would be benevolent or even benign in its conduct toward us. It might simply scrape us off the planet as we would a pest from a nice piece of fruit.

[spokeshave]

I was at a start up company a while back and the interest was in looking for evidence of either:

1). Nuclear fallout

or

2) Atmospheric pollution

as evidence of advance civilization

[wastedyears]

How long did that startup company last?
