	(Spoiler alert for the movie "2001: A Space Odyssey") The monoliths in the movie were not just the three individual monoliths mentioned here. Near the end of the movie, a huge number of them appeared around, and apparently merged into, Jupiter. The added mass of the swarm of monoliths is what allowed Jupiter to initiate fusion, transforming it into the star Lucifer. So, the idea of "monoliths" being a source for dark matter is a joke on the final component of the plot of 2001, not just a vague reference.

	:Your spoiler applies to the sequel {{w\|2010: Odyssey Two}} and it's highly unrealistic. The mass of Jupiter is about 75 times smaller than the smallest possible star having fusion. Meaning the swarm of monoliths would have the mass of some 75 Jupiters. But Randall puts monoliths into the range of obelisks and pyramids less than 10<sup>19</sup> kg. And if Jupiter would collect so much dark matter nothing would happen because dark matter doesn't react with normal matter except of gravitation. --[[User:Dgbrt\|Dgbrt]] ([[User talk:Dgbrt\|talk]]) 19:38, 23 August 2018 (UTC)		:Your spoiler applies to the sequel {{w\|2010: Odyssey Two}} and it's highly unrealistic.

 ::My point exactly - we now know quite a bit about the mass needed and process required to form a neutron star, making it unlikely the same mass would be able to form a black hole. I think that's what Randall meant in that part of the chart, but that's not what the explanation states. (Unfortunately, I've reached the point where I no longer want to argue with other editors over correct explanations.)

 :It seems intuitively possible, though. Imagine a black hole with the very lowest mass current theories predict they could form at, at the earliest point in time such a hole would be able to form. How much mass would it have shed through Hawking radiation since then? How far down into the neutron star weight class would it have gone by now?

	Can anyone explain how the paragraph associated with Buzzkill Astronomers has anything at all to do with a group of negative or skeptical astronomers?
