alfa015 Posted April 18, 2020 Report Share Posted April 18, 2020 (edited) 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. Edited April 18, 2020 by alfa015 Thoth101 1 Quote Link to comment Share on other sites More sharing options...
