The Schwarzschild radius for the mass of the observable universe is about 13.7 Billion Light Years while the observable universe is about 93 Billion Light Years

The Schwarzschild radius for the mass of the observable universe is about 13.7 Billion Light Years while the observable universe is about 93 Billion Light Years across (radius ~46 Billion Light Years). So the universe is not itself a black hole (until you take expansion rates into account)
- garmaine 6y agoI think you have that backwards--you have to take expansion into account for the "observable" universe to be that large, since the age of the universe is only 13.7 billion years.
