What if the advanced civilization treats us like the way we treat animals? In my view it's better to stay away from the advanced civilizations
We do have animal rights, don't we?
We do? Where?

#82120 light years away. If there was life out there, similar to us - could we detect their radio and television signals over this distance?
If we could get a positive confirmation of just anything living - even if it's just oceans of plankton - then that would revolutionize our understanding of the universe.
Actual, viable, recognizable lifeforms of extra-solar origin changes the inputs to a lot of our ideas about where and who we are pretty substantially (also some rather unfortunate possibilities about the great filter).

Things have gone poorly for them, but they didn’t know it would happen like this when they invaded. In theory the USSR could have greatly benefited from a short war that gained them resource rich territory at minimal cost like the previous time they invaded Ukraine and annexed Crimea in 2014. https://en.wikipedia.org/wiki/Russian_occupation_of_Crimea
However, an alien civilization has little reason to invade a planet they can’t live on. Imagine someone suggesting we invade Jupiter,

#841. I looked up the phase diagram of water. If the mass is 10 times the earth, their athmospheric pressure might be one hundred times of ours. At that pressure, water boils at about 300°C. If ambient temperature is about 200°C then their chemistry would be completely incompatible with ours. And with hydrogen athmosphere anyway. 2. Re the Dark Forest hypothesis: maybe. They will discover our radio in about 60 years (as…

Read more about the Dark Forest Hypothesis. I don't mean that this hypothesis is valid but it makes sense to think about it.

of course. photons do not experience time or distance, and are probably ageless

Reading you narrowly, I agree that of course you can always ask why an actor chooses a particular action. But I don't really understand your larger point, do you mean that all offensive wars are irrational? Because pointing out that wars in the history of planet earth have irrational causes is a long way away from explaining why an interstellar actor should attack whatever it sees.

The mass isn't directly correlated to the gravity (~5-6G assuming rocky planet density in this case) and the amount of atmosphere also isn't guaranteed. It might have an atmosphere that merely doesn't extend as far into space. Basically an anti-Venus since it has similar mass to earth but a much thicker atmosphere.
Of course. It's all ballpark.

If they are truly that advanced, they certainly already know about us. It seems kind of arrogant to presume that we could detect them with our primitive technology and they could not detect us. Most likely scenario is that they don't care about us in the same way we don't care about ants.
It's why I'm 100% it can't be advanced life: we can't find life anywhere in the galaxy but we find advanced life in our own backyard (I know 120 light years is quite a lot)?
That might just mean that life is rare, but inevitably becomes advanced.

I don't think Russia gained materially from that. While they ruthlessly exploited whatever resources they could get hold of in the Donbas, that of course that leaves the region much poorer so the have just concentrated wealth, not creates more of it overall.
