It seems like an owl to me, a Harry Potter reference maybe.{{unsigned ip|186.56.198.178}}
:Please sign your posts with <nowiki>--~~~~</nowiki>. But you are right, it's an owl.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 11:12, 21 August 2013 (UTC)

Clearly that owl is a reference to the owl who carries written messages in the Harry Potter series.

Google voice bills itself as a number that is "tied to you [the user]" instead of a device [like a phone]. Cueball is operating under the assumption that like begets like; that is, if I phone you, you are on a phone. Google voice negates this because it allows the user to control how messages reach the receipient. The comic takes this a step further and applies it to any method of communication [[User:Zim|Zim]] ([[User talk:Zim|talk]]) 12:32, 21 August 2013 (UTC)zim

;Pricing

Cueball's friend might just be avoiding expensive mediums. Because of how cellular carriers price their services in some countries, some plans charge far more for voice or SMS than for low-bandwidth data such as IRC or VoIP. Wired ISPs in many countries even offered unmetered data or close to it (Comcast's quarter TB per month). --[[User:Tepples|Tepples]] ([[User talk:Tepples|talk]]) 14:43, 21 August 2013 (UTC)

It is quite common that my mobile phone is off and reloading in another room, while I am actively engaged on my PC and receiving email immediately. So I kind of relate to the comic. With today's notification possibilities (SMS, Email, ...) and interconnected services (e.g. receive Facebook chat messages with a personalized facebook email address and be notified to another email of yours), this gets kind of confusing what is the individual's preferred way of communication.

Given that the Rick Astley one is on the same star as Portal, which came out in 2007, it's probably meant to refer to rickrolling (and thus the date should also be 2007 for that one). [[User:Zakator|Zakator]] ([[User talk:Zakator|talk]]) 10:55, 15 May 2013 (UTC)

All your base are belong to us didn't start as a meme in the 1970. I don't have precise data right now but I'm pretty sure it was 1997-99 when it first appeared on the internet. Also, what is the Sun doing? [[Special:Contributions/195.32.50.126|195.32.50.126]] 11:14, 15 May 2013 (UTC)

If you order the list by distance, further stars should get memes from earlier times, but this is not always the case.

Talk:1203: Time Machines

178.26.45.117:

This one kinda went over my head; the explanation is the best I could come up with. [[User:Alpha|Alpha]] ([[User talk:Alpha|talk]]) 05:00, 24 April 2013 (UTC)
: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. '''[[User:Davidy22|{{Color|#707|David}}y²²]]'''[[User talk:Davidy22|<tt>[talk]</tt>]] 05:13, 24 April 2013 (UTC)

My thoguhts:
Cueball turns on the time machine, which starts up and they start going back in time, returning to the time the machine it turned on. Time is going in perfect reverse, so the machine switches off and then he is back where he started. [[Special:Contributions/216.81.49.162|216.81.49.162]] 05:10, 24 April 2013 (UTC)

The Machine even turns back Cueballs actions, so maybe even his memory of turning it on, what might make him so puzzled - eventually - if he decides rational to try the machine (and if desicdes always rational) - he will get in a loop of turning it on - travelling back and forgetting that event - and turning it on again. - That might get Interesting [[Special:Contributions/212.202.64.10|212.202.64.10]] 05:32, 24 April 2013 (UTC) Lupo

I don't think he looks puzzled because nothing happened, I think he's curious b/c he just came across a Time Machine. That is, the last frame of the strip takes place seconds before the first. So the "trouble" with time machines (of this variety) is that if you go back in time you can't take the present with you, and nothing changes.
[[Special:Contributions/76.95.49.45|76.95.49.45]] 06:00, 24 April 2013 (UTC)

Alternative view: Feedback. Stephen Hawking has discussed the general problem with a whole class of time machines (namely, wormwhole based time machines), where the energy from the future is added exponentially to the system due to system feedback. More or less as a microphone cannot get too close to its speaker without having that horrible sound. This would explain who the guy in the comic turns the machine off... there is a large buildup of energy feedback and this can be observed in the EEEEE...

"In the end, I think a wormhole like this one can't exist. And the reason for that is feedback. If you've ever been to a rock gig, you'll probably recognise this screeching noise. It's feedback. What causes it is simple. Sound enters the microphone. It's transmitted along the wires, made louder by the amplifier, and comes out at the speakers. But if too much of the sound from the speakers goes back into the mic it goes around and around in a loop getting louder each time. If no one stops it, feedback can destroy the sound system.
The same thing will happen with a wormhole, only with radiation instead of sound. As soon as the wormhole expands, natural radiation will enter it, and end up in a loop. The feedback will become so strong it destroys the wormhole. So although tiny wormholes do exist, and it may be possible to inflate one some day, it won't last long enough to be of use as a time machine. That's the real reason no one could come back in time to my party.

Source: http://www.dailymail.co.uk/home/moslive/article-1269288/STEPHEN-HAWKING-How-build-time-machine.html#ixzz2RMMowXrs" {{unsigned ip|128.12.95.6}}

But with that above analogy, in a sound system, you have external power to amplify the signal - the energy the microphone takes out is not what gets put back out. In a wormhole, unless there is something to amplify the radiation that comes out the other end then it's a closed system (and if you do amplify it then where did THAT energy come from).

Another problem with this design of a time machine is that it draws power from the wall. What would happen if he crosses the time when there was no outlet at that location? Or no power grid at all? But that may not pose a problem here because it seems he doesn't get too far back into the past anyway. So, for our future time machine inventors: make those machines self-contained! --[[Special:Contributions/216.165.95.66|216.165.95.66]] 15:24, 24 April 2013 (UTC)

:I think that pretty much somes up why some people think you can't use a time machine to go back in time before the time machine ''itself'' existed. If it was an ancient time machine, you could go back quite far, but if one was made on February 5, 2013 you couldn't travel before that point because the time machine wouldn't exist before that time, so no time machine anymore, no travel. Hence what you said about crossing the time when there was no outlet. Cueball couldn't go back that far. --[[User:Dangerkeith3000|Dangerkeith3000]] ([[User talk:Dangerkeith3000|talk]]) 15:36, 24 April 2013 (UTC)

PRIMER!!!!!!!

== We're all trawling into the future, just like Cueball ==

Ugh! The original explanation (going back in time by one second) is drastically over thought. It's a "time machine" that does nothing other than make a noise -- just a box with a switch. Cueball turns it on, and a second later turns it off, thus having traveled through time into the future by one second. The T numbers are incrementing, just as they always do, even prior to a rocket launch. We're all traveling through time -- "all systems ARE normal." Please reconsider. Jeff.
