Oort Cloud, Again

Interesting article from Science News. I've previously commented about "faith" and the Oort cloud.

Now things get really interesting:

1. There should be no comets, but there are
2. Make up the Oort cloud
3. Calculate the mass of the Oort cloud
4. It's too big
5. Make up some new models
6. Declare success
   

Maybe there is an Oort cloud, I'm agnostic. But it would be really great if there isn't, I'd love to hear the new story.
