162.158.107.37: Referred to official transcript of 1644 to counter the claim about gender.

In the description for the earlier comic, it is quite emphatically asserted that this is not Megan (although it certainly is drawn like her) but is, instead, a male TV host. [[Special:Contributions/172.68.174.28|172.68.174.28]] 20:21, 9 July 2018 (UTC)MrBigDog2u
:Thanks, but I believe the transcript of the former comic was interpreted false. People are often outlined as male when they are in fact women. AND in this comic it's clearly a female without any doubt. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:11, 9 July 2018 (UTC)
:Actually if you go to /1646/info.0.json , you'll find the presenter referred to as he twice. Unless you're saying Megan uses he, it seems unlikely to be a female. ¯\_(ツ)_/¯ For what it's worth, I assumed it was a female until I read the explanation for 1644.

"Don't bother trying to catch them"??? What stellar object would you catch? Unless this is a reference to asteroid mining? [[Special:Contributions/172.68.90.28|172.68.90.28]] 22:47, 9 July 2018 (UTC)SiliconWolf

How the heck is a lava cake more luminous than a campfire? {{unsigned ip|108.162.219.28}}

:: Now the real question is, Why isn't lava cake included on the diagram?!?! [[User:Veleek|Veleek]] ([[User talk:Veleek|talk]]) 23:54, 20 June 2018 (UTC)

As it's a logarithmic scale, is it more correct to say the plot been expanded to 1 on both axes? [[User:Cgrimes85|Cgrimes85]] ([[User talk:Cgrimes85|talk]]) 15:47, 20 June 2018 (UTC)

It seems Randall thinks an astronomer is about as bright as a lightbulb, probably due to the Hertzsprung-Russell diagram itself! [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 15:52, 20 June 2018 (UTC)

::You seem to overestimate the attractiveness of most lightbulbs. I've only seen a few that I would consider really hot.

While wattage is used as an informal proxy for bulb brightness, there is not a 1-to-1 relationship between power consumption and light output. Incandescent bulbs in the United States were commonly labeled with both watts consumed and lumens output to aid consumers in choosing efficient bulbs.

I understand the explanation, but what's the joke?

The title text says "The Hertzsprung-Russell diagram is located in its own lower right corner, unless you're viewing it on an unusually big screen." But it's clearly on the top left corner... Am I missing something? [[Special:Contributions/108.162.219.106|108.162.219.106]] 18:47, 20 June 2018 (UTC)

:Why would it be at the top left...? The diagram itself is not particularly luminous, so would not be at the top, and its apparent temperature is quite low, so it would not be on the left.

Why is a blue whale considered more luminous than a campfire? Blue whales don't generate any light.

In one of the interesting parts of this diagram not that many mundane objects (or at least smaller than earth objects) are much hotter than most stars (surface temperature)... Not mentioned now.--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:33, 20 June 2018 (UTC)

I think the current explanation is still taking some of the graph too literally, thereby missing some of the jokes. After all, Randall creates comics, sometimes using innuendo or subtlety to make a point. I still think some of the items on the graph are plotted using luminosity as a measure of "brightness" in the sense of smartness. No offense intended, but he must have had a reason for including France below the planets and the blue whale above the astronomer. Furthermore, the title text is likely talking about the actual HR diagram not being very "bright" in the same way the astronomer is in the lower-right corner of the graph, except when it is displayed on a jumbotron. If you're an atronomer, you might not like hearing this, but the meaning of the HR diagram is difficult to grasp correctly. To leave out any mention of smartness is likely missing the most significant jokes in the comic. Please feel free to disagree, but remember it's still just a comic!

How come this diagram says an LED bulb is hotter than a lightbulb, and both are hotter than a campfire? That doesn't seem right. [[User:YM Industries|YM Industries]] ([[User talk:YM Industries|talk]]) 01:49, 21 June 2018 (UTC)
