>>11378091the observable universe is approximately 40 billion light years across, if you factor in the expansion on top of the 14 billion year age. the size of the inflationary bubble we live in is probably exponentially bigger than that, say 40 billion light years times e^x for some x in a natural range like 1-100. in the chaotic inflation scenario the cosmos is even exponentially greater than that, like e^(10^100) or greater. the topology of the cosmos is unknown but it may be infinite, and if you combine that with the chaotic inflation scenario then it is infinite but expanding exponentially also
