I like to think of things as infinite and similar to bubbles if you will. Take each big bang as a bubble and then throw in a mix of variety, distance and timing for good measure. Some expand and pop, some shrink back down, some join together and it's a continuous ebb and flow just like most things we observe. I'm yet to observe or read about one singular unique thing, entity or observation which is why I like to follow the bubble theory so to speak. How does that relate to our bubble (universe) ending? It could expand and then pop spectacularly or it could just shrink back down to nil. It would be cool to join with another bubble (universe) but the collision will wipe us out anyhow. I have no idea how things will end but I feel comfortable that bubbles over time and distance will always be present and give rise to many forms of life. We just happen to be at a great time of learning and technology in our own bubble. I hope to see some interaction of those bubbles/life forms in my time here but I do not think it's probable. Bring on the crazy light show for my ending please, at least I'd have good seats to watch from :)
