Voyager mission in deep space

Probably, in all its enthusiasm, the Voyager mission left safety precautions about maintaining confidentiality on humanity and discloses on board, many uncomfortable details about earth and humanity!

By the time Voyager gets somewhere where the confidentiality might be an
issue, the human race will either be extinct, or will be well able to
look after itself against any puny aliens.

We have been broadcasting our presence by radio and tv for how many
years?

not only would ETs know we exist, but lots about our actions Wars
etc.........

i wonder how far the futherest radion waves have traveled by now?

putting it another way, if we were the ETS would we want to go meet
people liker ourselves?

That's such an easy physics question even I can answer it! Radio
travels at the speed of light so given our radio has been
transmitting for at least a 100 years our transmissions have traveled at
least 100 light years distance.

As has been said many times before, the signals we have been sending out
are very low power and therefore very short range. It wouldn't even
reach the nearest star outside our solar system.

thats assuming the ETs receivers are no better than our own........

It's all of the background noise that would be a problem. Even if they
could amplify the signal, they'd also amplify the background noise.

Physics. Learn some.

That's not entirely true.

For example, http://en.wikipedia.org/wiki/Arecibo_Message was quite
high-powered. Now, it won't reach anything significant, but anything within
38 light years along that line could probably detect it.

We also have http://en.wikipedia.org/wiki/A_Message_From_Earth.

Those are just the intentional ones.

Some of the high-powered military radars that were pointed over the horizon
are probably detectable by an advanced civilization.

That said, SETI does have some severe limits. For example with intentional
messages such as the two above, if you blink, you miss them.

And otherwise, we're starting to go relatively radio silent as a) we're
using radio more efficiently (and more ground-based communications in many
cases) and in general, the signals we're transmitting are often compressed,
which means that they look more and more like plain noise.

And you must include radar events like observations of Mercury, Venus,
and asteroids by Arecibo. The radar signal was huge, the distance
great, and the target small. The signal would have continued out into
deep space in whatever direction it was pointing, save for the small
fraction of it that hit the target and bounced back. Our transmissions
to the Voyagers and Pioneers by the DSN have also been extremely
powerful. They would have been detectable, at least as a unnatural
source.

There not the ones Bob was talking about nor are they the ones I
mentioned. I agree with your point about military radar, but it would
probably also look like noise.
