- Good golly, is it really necessary to state this? The angular momentum
- of the solar system keeps it from collapsing! Without it, the solar
- system would collapse in a few years. Same argument for superclusters,
- etc. The universe, OTOH, appears to have negligible net angular momentum,
- but also has much lower average density.
