Exactly, except that in the usual convention it is now about twice that because the pieces of the path already traversed by the light then got expanded after that...
Except if you prove a bang, or provide evidence for a bang, that does not matter. The following set of possibilities pretty much encompass all that is left to explain.
The universe has a bang and the time is known, or it was beyond the alleged bang and then we don't know.
The universe was a point, or a slightly larger point not including zero, or bigger, or even infinite at the bang. Stuff happened after.
Bottom line, the observable universe limits don't mater in the scope of the big bang. You have to observe new physics or evidence for new physics.
I LOVE the observable universe, and will not speculate beyond that.
