- Lately various popular models (eg CDM) have been coming under pressure -
- but in all honesty, if you ask two theorists, you'll get three opinions,
- so take everything everybody says with a grain of salt. We don't really
- know enough to rule many of the models in or out (plus, using two kinds
- of dark matter doubles the number of free parameters! You can fit models
- where the universe is a giant slab of stale tofu with enough free
- parameters, IMHO).
