Many physicists have pointed out several flaws in the dark forest theory, which makes for a great read but doesn’t really carry over to the real universe 1:1.
What flaws? Do they apply to variants such as Greg Bear's and related ideas such as berserkers?
Why would physicists have anything useful to say about this theory?
Can you point me to more info on that or just tell me? I am curious about reasons to be more optimistic than that book lays out. I would much prefer the Carl Sagan view of the Cosmos as one where it simply makes no physical nor cultural sense at all to be aggressive toward other stellar civilizations.
