? about radio & TV signals

Hi Group,


I've wanted to ask this question for a long time.

On a show about SETI, one of the engineers said that anybody coming our
way would start to encounter radio, and then TV signals.

About 75 and 60 light years out, respectively.

Is that really true?

Are "Amos & Andy", and "I Love Lucy" still flying through space?

How can they just go on and on?

The answer appears to be Yes. Most radio transmissions of early days
would not get out of the atmosphere, but TV transmissions almost
certainly did. This means that hypothetical aliens 70 light years out
will be picking up the London Radio Exhibition of 1935, followed by
Adolf Hitler opening the Berlin Olympics in 1936.
The signals do of course get weaker the further you go (inverse square
law), and you'd need a pretty good radio-telescope to pick them up at
that distance.
This was used as the basis of at least one SF plot, by Carl Sagan in the
original version of `Contact', later made into a movie. On reflection,
however, as the late Mr Sagan said, it obviously hasn't happened, any
aliens picking up our TV transmissions would have been here and wiped us
out long ago.
Regards,
Ray.

Maybe they did come and just wiped him (Sagan) out. Ever consider that ?

The unified field is deduced reciprocal, nuff said. Carefully
study your discipline for it leads to discoveries of much greater
enlightenment. The speed of light is perceived fixed but where it can go
is relatively unbounded since the base quantum energy field is infinite.
Hmmmm, well enjoy your smoke and depending on your relative location
always watch out for the hungry bears. Better to stick to common fun for
the high risk stuff is high risk.

Well Moe as Officer Bert had reported had huge antennae for he
most likely was communicating with close friends all the time. It's not
how big your tool is sometimes it's how well you apply it. Dr.
Einstein's brain appeared normal but packed a power punch. The net Seans
have affirmed other life forms in distant planets with or without huge
antennas. And magnets think powerful magnetic principle understanding
for it's permitting our modern way of life.

Yes and Morse about 100 Light years out.

ReeferGuyT

Yes but the signal strength goes down as 1/r^2 where r is the distance away.
After about 1 light year the voltage per meter of our feeble transmitters
drops to less than the galactic hiss and cannot be detected.

Remember the Christians will do anything to discredit those who believe in
life in space those Christians are just terrible killers and liers. They
are as evil as the most evil empire on Earth, far worse than the Kilingon
empire....
