But as there is just one universe (or multiverse in some popular cosmologies), then there can be just one science and so different views on some matters reflect either developing science or ignorance of science.
I am stating how this makes "me feel", not how "you should," about my "neighborhood," or universal locality. How many solar systems are there in our galaxy? How many Galaxies are there in our universe? If, just if, we were able to somehow transverse a great distance, and observe a "sub-intelligent" life-form, with cognitive reasoning ability ... how would we treat them? how would they perceive us?
This is deep ethical territory in the matters of perception or perspective. What if we found a planet, but we didn't have nifty "life-scan" detectors. What if to explore it we actually hand to land and do it? And in the process we came across "lizard-cave men", maybe they even watch us land. What would they think of us? How would we treat them? Would we try to "force" knowledge into their minds with machines? Would we interact with them at all?
Now, flip the coin, what if they came our way?
What if so many thousands of years ago, when an arm of sagittarius could have very well been extremely close to our "neighborhood", we had some visitors? When is that arm band due to come back around again? Wasn't there a recent discovery about the milky-way "eating" sagittarius? inter galactic immigrants, possible? Maybe though, they aren't limited by the distance but I'm sure the "ride" wouldn't be as long. Who would want to come here? Look at how we treat each other. Hello earth, there is no god we have proof! Would they say that? What could we reason them to believe?
But out of the billions of things out there, I suppose, like people on earth, we and I are the only ones. There is no need for morality astringent ethical codes, within reason.
Is that really all that stupid?
