Dear all,
The term "big bang singularity" somehow seems to imply that the universe had zero extent at the beginning. But should this really be taken literally? Because if something has literally zero extent, then not even exponential growth over billions of years could ever result in an extent greater than zero, could it?
So if the universe has an extent greater than zero now, and we assume that it is approx. 14 billion years old, then it must have had an extent greater than zero at ##t = 0##, right?Robert
