Reply to comment by wockyman in The Oort Cloud Could Have More Rock Than Previously Believed, Study Says by Additional-Two-7312
No, despite the headline their results overlap within the uncertainties of previous estimates of how much rocky material is in the Oort cloud.
Which is 0.1%-10% of the Oort cloud (this measure favours the high end, but it's one object). Still, let's say 10%.
The Oort cloud is ~0.01% the mass of the Sun
Stars are ~10% of ordinary matter.
Ordinary matter is ~10% of (Ordinary + Dark) matter.
So it falls ten million times short of what you'd need (as an order of magnitude estimate)
