Howde all. With reference to matter originating from the big bang. Nothing else. No multiverse, no pbranes - nothing. Just the Big Bang. Ok - given that galaxies are moving away from each other - then there is an overall outer edge shape created by these galaxies. Lets say now that you can hold this "shape" in your hand. What does it look like? a) A donut? b) A soccer ball? c) A rugby ball/american football? d) Saturn? e) A spiral galaxy? f) Science does not know? Cheers all.
