Would a concept exist if the one's who 'think' the concept are gone?

Question

Namely, humans. For example, if all humans were dead, if all life were dead completely, would the concept that 1+1=2 exist? If nothing existed, would 'nothing', the concept, exist?

Answer 1

That's what I always say about love. If the minds in which this concept is realized and experienced are gone, then love is gone as well.

Answer 2

A concept comes from not just a guess but because it is what it is.1+1 will always add up to 2. But if no one is here does it stop? Just the thought of it stops because no one is here to keep the concept going. Thus. it is like a law of nature 1+1 will always = 2 whether or not someone is here to verbalize it or comprehend it.
Your what if question "if nothing exixted would the concept exist. It can't exist in nothingness. That is a Mu question.
(japanese term) There is no answer to this because the question is based on assumptions. Nothing isn't anything....really we can't comprehend it. It is a question that can't be answered.

Answer 3

yes because it existed at one point. no one may know the concept, but it's still been thought of at one point.
