the article refers to travel not just by the species itself but by machinery that is not limited by lifespan, which in theory would also be observable. We have probes that have left the solar system through this means. not to mention just the simple example of radio waves.
- BerislavLopac 7y agoThe lifespan (either longer human, or mechanical) of individual travellers does not affect the speed of colonisation, so any communication would be quite limited. Which means that there be will be no interstellar "empires" or even cultures -- and if any habitable worlds are as rare as it seems to be the case for us, I'm not very optimistic about encountering any alien species any time soon.
