Am I the only to one who is amazed at just how *far* Voyager has come? [[Special:Contributions/162.158.111.61|162.158.111.61]] 19:52, 10 April 2019 (UTC)<br />

I thought the dark disk on the photo is 2.6 Schwartzchild radii, not 1? --[[Special:Contributions/172.68.54.46|172.68.54.46]] 20:50, 10 April 2019 (UTC)<br />

I Googled to get a sense of scale. Apparently the sun would be less than 4 miles across if compressed into a black hole. The magnitude is incomprehensible. [[Special:Contributions/172.69.210.64|172.69.210.64]] 02:54, 11 April 2019 (UTC)<br />

I believe "Voyager I" in the title text is a typo and Randall meant to say Voyager II. The location Randall notes would correspond closer to Voyager II than I(9.3 billion miles away from earth vs 11 billion miles).

Even though space is cold, it conducts so poorly that spacecraft would probably have more problems getting rid of heat than keeping heat, considering how isolated they are. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 16:43, 22 February 2019 (UTC)<br />

- It actually has little to do with conduction; the heat radiates pretty effectively, especially as it gets "hotter" vs the surrounding radiation. [[Special:Contributions/172.69.69.124|172.69.69.124]] 17:35, 22 February 2019 (UTC)<br />

I put in how the title text makes a probable reference to game development. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 17:41, 22 February 2019 (UTC)<br />

This seems to be in the same vein as two other recent comics, Internet Archive and ArkXiv. Perhaps real things that seem unrealistic is a new topic of Randalls? [[Special:Contributions/172.69.247.4|172.69.247.4]] 17:53, 22 February 2019 (UTC)</div>172.69.247.4
