The discussion centers on the nature of the universe and what it is contained in, with participants suggesting that the universe is not contained within anything. It is proposed that the universe's curvature is intrinsic and that if it is an n-dimensional universe, it cannot be contained in a higher-dimensional space. Questions arise about how the universe can expand if it is not contained, leading to references to Stephen Hawking's 'no boundary condition' as a plausible explanation for a finite yet unbounded universe. The conversation reflects on the complexities of understanding the universe's structure and expansion. Ultimately, the nature of the universe remains a profound mystery.
