SUMMARY

The discussion centers on the feasibility and implications of attempting contact with extraterrestrial civilizations. Participants reference the work of Claudio Maccone, who suggests that no advanced civilizations exist within 500 light years. The organization METI (Messaging Extraterrestrial Intelligence) is mentioned as actively pursuing communication with potential extraterrestrial life. While some view the speculation as interesting, others argue that previous broadcasts, such as 'Howdy Doody', have already sent messages into space, rendering further attempts unnecessary.

PREREQUISITES
  • Understanding of METI (Messaging Extraterrestrial Intelligence)
  • Familiarity with SETI (Search for Extraterrestrial Intelligence) programs
  • Knowledge of the implications of broadcasting signals into space
  • Awareness of the distances involved in interstellar communication
NEXT STEPS
  • Research the methodologies used by METI for messaging extraterrestrial intelligence
  • Explore the historical context and findings of SETI programs
  • Investigate the implications of broadcasting television signals into space
  • Examine the theories surrounding the existence of advanced civilizations within 500 light years
USEFUL FOR

This discussion is beneficial for astronomers, astrophysicists, science communicators, and anyone interested in the implications of interstellar communication and the search for extraterrestrial life.

I would like to know your opinion about this.

Do you think we should try to contact aliens?

I think it's safe as long as we choose stars as old as the Sun or younger.

I also think that, if a nearby civilization hasn't contacted with us yet, it's probably because they don't have the means to do so.

Actually, according to Claudio Maccone, there are probably no advanced civilizations within 500 light years.

There is an organization called METI, that tries to message extraterrestrial intelligence. More info here.

It's all speculation and if you ask 10 different people, you'll get 11 different opinions with emphasis on different aspects of the whole thing. Personally, I think it can be interesting speculation but as a practical matter it's a waste of time.

We've already, albeit somewhat inadvertently, messaged the whole Universe ever since the first episodes of 'Howdy Doody' being broadcast in UHF, so let's please hope that 'they' like USA TV.

While funding remained erratic, as Carl Sagan indicates*, NASA and other agencies have run SETI programs for decades. Not all projects involved passive listening. We have transmitted coded signals into space along with radiating "I Love Lucy" re-runs before cable TV predominated.

Someday a flying saucer will land on the National Mall, loudpeakers will engage, and we will hear a booming Cuban-accented voice, "Lucy...I'm home!"

The aliens are going to think we are some weird beings if all they see is howdy doody.
 
Hi Flatland:

My opinion for a variety of subtle reasons: Communication with distant aliens cannot do the people of Earth any more harm than not communicating with them, if any such beings actually exist.

Regards,
Buzz

If true, I'm not convinced that "communication" is possible.

Us: AD2020: "Hey there!"
...
...
Them AD3020: "Wazzup!"
Us: AD3020: "Hey cool, how you guyz doing?"
...
...
Them: AD4020: "What?"
