Will we always be "observing"? Hello everyone, I am from India. Have been an astronomy fan since childhood. Have also been reading this forum since quite a while. Looking forward to interact and learn from knowledgeable people here. Now coming to the topic, let's say we detect intelligent life in our neighbourhood (10 LYs for example). We can "understand" each others languages. LSB would mean that the 2-way communication is basically useless. It would take 10 years for transmission to reach to the other side. So we can basically say goodbye to communicating with any intelligent life form, and the mere thought of traveling sounds like a joke. Therefore will we always be in "observation" mode?
