>>20Aliens that have been space faring for a very long time will have convergent evolution, because they would all try to adapt their physiology to the same environment in space at least to some extend. I would imagine that space aliens would get tired of immediately dying when exposed to hard vacuum, or getting major health problems from zero gravity.
>alien technology we don't understand.Science and technology development will be similar for all species because they all have to work with the same fundamental building blocks of reality. If these aliens are not fundamentally more intelligent than humans and just further along on more or less the same technology ladder, than it would be like somebody from a few thousand years ago seeing modern technology. Very confusing, only for a while.
>we probably would have trouble making sense of themyeah communication would probably limited, they probably have invented very similar math tho.
>>23>Confirmation of aliens would have a huge impact on people's worldview.Really ? Popular culture has had a lot of Aliens for a long time, so it's not like people haven't been confronted with the idea.
