I think you&#x27;ve misinterpreted my post. The &quot;No&quot; was in response to this:<p>&gt; That always confused me. We have an Oort cloud, whose members we cannot resolve very well&#x2F;at all. Why do we assume only our star has such a thing? If all stars did, that isn&#x27;t enough mass to explain dark matter?<p>No, that isn&#x27;t enough mass to explain dark matter, since it&#x27;s only 0.1% to 0.2% of the mass of the solar system.<p>The text I quoted was in complete agreement with what you and others have posted. I was pointing out that the questioner&#x27;s point had already been answered.
