SUMMARY
The discussion centers on the conceptualization of the universe's size and nature immediately after the Big Bang (BB). Participants assert that if the universe is finite, it was extremely small post-BB, yet if it is infinite, it has always been so. Key points include the distinction between the observable universe and the entirety of existence, with emphasis on the universe being finite yet without boundary. The conversation highlights the complexities of visualizing the universe's nascent state, suggesting that it may have occupied the smallest possible quantum of spacetime.
