When you read the piece below consider the time the signal is going to take to reach its intended destination:

November 16 2018 marks 44 years since researchers sent
humankind’s first interstellar radio message – an achievement Google is celebrating
with a Google Doodle.
The Arecibo Message, sent from the Arecibo Observatory in Puerto Rico in 1974, is a three-minute message of exactly
1,679 binary digits – which, if arranged in a specific way, can explain basic
information about humanity and earth to extraterrestrial beings.
Scientists sent the message via frequency modulated radio
waves to a cluster of stars 25,000 light years away to demonstrate the power of
the Arecibo
radio telescope, which was the largest and most powerful in the world at the
time.
“It was a strictly symbolic event, to show that we could do
it,” Cornell University
The event moved some present to tears as researchers
contemplated their own existence and knowledge of planets and solar systems.
The hope is that, in many thousands of years, it may reach
another living being.
The actual message was devised by a team of researchers from
Cornell University
When received, the message could be arranged in a grid 73
rows by 23 columns to form a pictograph that represents facts about
mathematics, human DNA, planet earth, and humans.
From top down, the seven-part message can show the numbers
one to 10, atomic numbers of elements including hydrogen and oxygen, the
formulas for the sugars and bases in the nucleotides of DNA, a graphic of the
DNA double helix structure, a figure of a human and the population of earth at
the time, a graph of the solar system, and a graph of the telescope.
Since the Arecibo
message was sent, the message has travelled just 259 trillion miles – a
fraction of its journey to its intended destination, which will take roughly
25,000 years to complete.

********************************************************
25,000 years for the message to reach its destination. If it
reaches an intelligent life form -if- there is the 25,000 year wait for a
returned message. Now, personally, I think sending a message to show off is
pointless. I certainly do not care when
it gets to its final destination. I won’t
be alive and I think it is fair to say that no one alive today will be!
Will Earth still be here in 50,000 years? Humanity? And those are the two minor
questions because the main one is will any civilization exist in the area the
signal is heading? Rather like the
Voyagers (I and II) their journeys will take thousands upon thousands of years
if they are not destroyed in some collision and, again, this was showing
off. Planetary information from both was
fantastic so why not just set them to randomly float around the solar
system. I know there are a lot of
problems because of age and so on but surely someone must have thought it
better to keep roaming our system than become a piece of space litter?

I really do not care that in 40, 60 or 100,000 years an
alien space ship may find one of our probes.
To them it may well send a cheery message of “there was intelligent life” out in space.
Again, I personally do not think any advanced alien
civilisation would be using radio signals or sending out probes to say “Hello.
We’re dead now –sorry you missed us!”
The Andromeda galaxy has an estimated (it may be raised in
number at some point) 1 trillion stars. The European Space Agency’s (ESA) Gaia
space craft is 3D scanning space and has made somke excellent discoveries. It
has created a 3D map of 1.7 billion
stars in the Milky Way. Read this item if you are interested: https://www.space.com/40406-gaia-release-color-milky-way-map.html

billion stars from the Gaia spacecraft, giving the best-ever view of the Milky
Way and neighboring galaxies in color.

Here is a little fact: As of the 1st November,
2018, there have been 3,874 confirmed planets in 2,892 systems, with 638
systems having more than one planet. If you want more information on how these
are detected and distances from Earth then there is a very good Wikipedia entry
here: https://en.wikipedia.org/wiki/Exoplanet
We should all know about the “Goldilocks Zone” where we
would expect to find habitable or Earth-like planets. So here is another little
fact for you: in November of 2013, astronomers reported, based on Kepler space
mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of
Sun-like stars and red dwarfs in the Milky Way, 11 billion of which may be
orbiting Sun-like stars.

Remember that we only recently discovered “Ghost Galaxies”
and that there are suns that travel between galaxies –when it comes to knowing
about our solar system and the universe our knowledge is of perhaps about 0.5%.
We should be sending radio signals and messages shorter
distances and, considering objects the size of Oumuamua are only discovered by
chance, we need to make sure any signals are broadcast throughout our solar
system.
Science also needs to get involved in the subject of UFOs
but only in the sense of looking at the data and assessing reports –unexplained
does not mean “alien” but it would offer us a basic data base to build on and
study. The unwillingness to do this is
unscientific and, I believe, cowardly. Hopefully it is just through closed
minds rather than fear that their highly paid jobs might be at stake.
That those involved with SETI will not become involved is,
to a degree, and we have to be honest, it is understandable. Hopkins , Jacobs et al have made it so that the subject has become farcical. “Millions”
of people abducted year in and year out to create a race of alien half-wits.
But we need to concentrate on those reports both old and new
that have largely been left untainted and there are many.
*We are not talking about hundreds of flying saucer crashes
and many hundreds of dead aliens
*We are not even looking at extra terrestrials visiting
Earth over the centuries as there is no evidence of this except that presented
by the bunko crew.
*We are certainly not talking about “many millions” of alien
abductees.
*We are not talking hundreds or thousands of extra
terrestrial space craft being sighted each year.
What we are talking about is far less, rarer activity and,
being honest again, re-assessing all of the old reports has left me realising
that there is evidence there –even if
only anecdotal. 100% evidence is not possible since if landing traces,
radiation and other physical evidence is ignored by sceptical ufologists and
debunkers (the same thing) or simply waved off as being unexplainable and
therefore “not evidence” I doubt that anything would convinced a closed and
frightened mind.
By definition, and I find this almost laughable, doing the
work I am it is safe to say I am far more involved in SETI than most of those
working within SETI!
We really need to get our act together and forget what might
happen in 50,000 years!
