general relativity - Schwarzschild Radius of the Universe


According to the Wiki on the Rs, the Rs of the observable universe is 13.7BLY.
https://en.wikipedia.org/wiki/Schwarzschild_radius (The observable universe's mass has a Schwarzschild radius of approximately 13.7 billion light-years.[7][8])


The reference for this statement is:


https://arxiv.org/abs/1008.0933 and the Encyclopedia of Distances


Can someone please explain this to me... Is this simply because to get into the non-observable portion of the universe, you have to go faster than the speed of light?
