# If Proxima Centauri is only 4.25 light years away, why is there no attempt at communication? [closed]

It is known that the Proxima Centauri star system is merely $\approx 4.25$ light years away from Earth. Moreover, an Earth-like planet has been discovered around Proxima B that is within the habitable zone. Given that there is such a short distance for potentially establishing communication with a hypothetical civilization, why is it that:

• There have been no serious attempts at sending signals to that system - even if there is a very slim chance of receiving a response, surely the fact that there might be one in only $\approx 9.5$ years is a scientifically motivating one?

• I understand that some people, like Hawkings, argue that contact with such civilizations should be avoided. Still, I see no significant debates about sending a signal to Proxima. Surely, there would be a number of scientists who support the idea to initiate a debate on the subject?

So, what gives?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

• I have voted to close because I think answers will be primarily opinion-based. This is not a question about physics, but about reasons for or against trying to communicate with possible alien life. – sammy gerbil Jun 19 '17 at 15:13
• I'm voting to close this question as off-topic because it's about reasons for sending signals (or not) to (known) exoplanets and not physics. – Kyle Kanos Jun 19 '17 at 19:30
