This is exactly what I'm saying. Just because we can not detect something doesn't make it non-existant.I couldn't help but spot this: you seem to be saying that something undetectable can logically still exist.
And your point is...?"Having the ability" to interact, implies that it would interact with any measurement process (which would involve work, and energy output). If it doesn't-=then it cannot be said to exist, at least ont logically. Then you can only imagine that it exists. An observer's POV is one of observation, not imagination.
I'm sorry - I'm not clear on what point you're trying to make here?
I have clearly stated previously that something that can not be detected is "logically consistent" with something that does not exist - but this is not the same as saying that "it definitely does not exist". One can only claim that IF one had the ability to detect at an absolute level.
Which is why I define existence that is everything that is "able to interact" - i.e. "able to be detected" - whether they are or not.
