As far as I can figure out, -452 F is something like 4 K, which seems a bit too warm (above OTL microwave background). It probably should be -456 in the next-to-last row and -458 in the last row (-459 for the last column). --141.101.81.76 12:58, 20 November 2015 (UTC)

There will be ambient starlight in addition to the 2.7K background which should raise the temperature slightly. However, the 2.7K background will also redshift to a lower temperature as time goes on: T propto 1/a where a is the scale factor of the Universe. Would be a good assignment for a cosmology class. 173.245.54.48 13:07, 20 November 2015 (UTC)

There are five columns. Either the first column is "today" and one should not speak of predictions after five (m/b/trillion) years (as is currently the case a couple of times), or the first column is "tomorrow (etc.)" and then the prediction of "A bright yellow sun; 38°F" for one trillion years would be very strange.

If the "red giant" temperature measures the sun's core, how do you explain the last panels showing decidedly non-white-dwarf temperatures? --199.27.130.234 03:48, 21 November 2015 (UTC)

Regarding the 5-year-predicion: It seems to me that the temperature is in average rising a bit across the year, maybe a reference to the slow process of global warming? This would not be the first time, there are even whole comics just about global warming, especially about the noticeable speed and the "in average"-importance (e.g. 1379, 1321)
