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)
Thanks for the conversions to degrees C as being a 58 year old Brit I have never understood degrees F (I know what they are just I have no idea whether 60F is cold, cool or comfortable). I have always used 5, 10 and 21, Winter, Spring and Summer sun - well works for Middle Brittan) RIIW - Ponder it (talk) 19:09, 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)
Aha, what will last longer than stars etc is the silly Fahrenheits. 162.158.91.165 17:49, 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.
