If our view of the universe shows an infinitely compressed point of matter expanding, what can coax such expansion? An infinite surround of nothingness. Which must then be contained within what? More matter; endless ripples. As another commenter posited, a space-time surface that is curved along itself, perpetually. It doesn't negate the big bang, or the great death, rather it relies on these two properties - but exclusively and reductively. The original comment was regarding a cyclic universe - which I agreed with. Perhaps my use of the term "perpetual", while accurate - was confusing. I don't disagree with the big bang, we've observed it directly.
