This one kinda went over my head; the explanation is the best I could come up with.

:Examine the transcript and Cueball's movement in the second and third panel. The time machine in this comic is a time-reversing one, not a time jumping one.

:The wormhole itself does not need to amplify the energy, because it isn't a closed system; more enrgy is being added to it. Interestingly though, this leads to another problem: creating a time machine portal would quite lossibly lead to the instantaneous heat death of the universe. Here is the problem: the instant the portal is opened, radiation moves through. When it comes out in the past, it fractionally increases the total energy in the universe. Logically, after the time until the wormhole is created, the energy will spread out enough that there is at least a chance that the radiation passing through the wormhole will be slightly increased. This causes ian infinite loop, or at least a loop that so dramatically changes the earth that the time machine is no longer created.

A more generalized flow chart explaining the problem with time machines, assuming you get to keep moving forward: http://i4.minus.com/jqqrkqg1QKp84.png --[[User:Willowy burrito|Willowy burrito]] ([[User talk:Willowy burrito|talk]]) 13:17, 24 April 2013 (UTC) | A more generalized flow chart explaining the problem with time machines, assuming you get to keep moving forward: http://i4.minus.com/jqqrkqg1QKp84.png --[[User:Willowy burrito|Willowy burrito]] ([[User talk:Willowy burrito|talk]]) 13:17, 24 April 2013 (UTC) | ||

I thought perhaps that the idea was that when he flips on the time machine, time does proceed, but at normal speed. Therefore, the "time machine" is just a box with a lever on it that does nothing. {{unsigned ip|173.245.54.79}} | I thought perhaps that the idea was that when he flips on the time machine, time does proceed, but at normal speed.

| − | As pointed out above, the outlet changed | + | As pointed out above, the outlet changed. It appears to be a hint that the time traveler went back to "correct" [https://www.explainxkcd.com/wiki/index.php/567:_Urgent_Mission Benjamin Franklin (567: Urgent Mission)], hence the power change. At least 3 other things changed, if we assume the switch travel was around 1 second and allow the sound to change when the switch leaves whichever position it was in (as if there's a small switch for windup/down when it begins travel): First, there's Cueball's hand position. He actually appears to be "pulling" the lever down from the "bottom" which would explain his puzzled response. Gravity "work" is now in the opposite +/- direction. The outlet's already been mentioned but the cuts look like a "+" to me (instead of parallel slots as they are in the United States). Next, when NASA exceeds "0 seconds" the countdown reverts to a countup ("T+1 second and counting"). Except this starts at 10s and perhaps in the opposite direction expected, which implies (assuming Cueball is approximately 6 feet tall - or 1 meter) that the equation for acceleration due to gravity has been flipped (instead of 9.82m/s^2 ... travel of one meter equates to approximately 10s). These are all "nominal" changes, but the problem with "nominal" is that within a "named tolerance" is approximate but not exact. I think there's an additional joke in "E" (its deliberate use and how it changes) but the point is: These are the uncertainties we file under "negligible" in a butterfly's wings. |
