Nothing is an abstract concept to define the absence of something, that is, nothing is nothing and you cannot imagine it or put it in a context, because if you imagine something, it is already something and then it is no longer nothing, it is like saying, what is darkness?, well it is the absence of light, let's say that nothing is the condition of things until something appears

Yes I agree

I think I'd like to have light in replace of darkness

it is like when you try to think of nothing but you can not becase thinking nothing is thinking something
