Comment on What do you think realistically would happen the moment we meet extraterrestrials?
notsosure@sh.itjust.works 2 days agoOne of the most notable substances found on Earth but likely absent on most other exoplanets is liquid water. Another candidate is free oxygen (O₂) in significant quantities. On most exoplanets, oxygen is often bound in compounds (like CO₂ or H₂O) rather than existing as a free gas in the atmosphere.

I’d imagine for a civilization advanced enough for not only interstellar travel but suggestively FTL if they are running some kind of logistics operations across star systems, they would not have issues neither of hoovering gas clouds or splitting molecules and recombining them into desired materials nor have a problem with any amount of energy required. Damn, their physics and chemistry is probably at a quantum level so they can make whatever elements they want and have the need of none.
Unless FTL travel and communications is stupid simple that we have missed some basic discoveries that would solve the Fermi paradox because we didn’t know what to listen or look for.
