Hahaha no but a good answer. This one is actually pretty complex at its core, but basically, the proof begins by recognizing it is true that either everyone in the pub is drinking (in this particular round of drinks), or at least one person in the pub isn't drinking.matrix3509 said:Then he is the only person in the pub.

Ah I see, but then, just to be a douche, I could just invoke a solipsist argument, that if I am in the pub, I am the only real person in the pub and all others are a product of my unconscious, therefor if I am drinking, everyone in the pub is drinking because I am the only person who is real. *gets punched in the ear* *bleeds* Ow damnit thats what I get for invoking that stupid stubborn solipsist argument again.mafyapenguin94 said:Hahaha no but a good answer.

On the one hand, suppose everyone is drinking. For any particular person, it can't be wrong to say that if that particular person is drinking, then everyone in the pub is drinking — because everyone is drinking.
Suppose, on the other hand, at least one person isn't drinking. For that particular person, it still can't be wrong to say that if that particular person is drinking, then everyone in the pub is drinking — because that person is, in fact, not drinking.
Either way, there is someone in the pub such that, if they are drinking, everyone in the pub is drinking. Hence the paradox.
What assurance do we have that the barber is even a man?Maze1125 said:Or the barber could be lying/mistaken.twitchingace said:Could the answer not be that the barber a child and therefore not a "man"? Or better yet, could he just have no facial hair to begin with, maybe he went through chemo or something... pretty much just grasping at straws but still. Or maybe, just maybe, the barber doesn't live/work in the village, just the men from the village come to see him for a shave.Suppose every man in a village is well shaven everyday.
A barber claims he shaves every man in the village who doesn't shave himself.
Question:who shaves the barber?

Well, obviously.Hurr Durr Derp said:As I mentioned before, in a situation where the timeline diverges there wouldn't be a paradox either way.
But cause and effect only exists within time. There is no cause and effect within the loop because, as you say, the loop is imaginary. Therefore your grandfather must be both alive and dead as the same time, which is a paradox.It's not a literal 'Groundhog Day'-kind of loop, but more of an imaginary loop of what causes what. Your grandfather's murder causes you not to be born, which cause you to be unable to kill your grandfather, which causes you to be born. That these options essentially happen at the same time is true in a linear point of view, but since time travel is involved the cause-and-effect line is not the same as the timeline.
Actually, since infinity squared equals infinity, infinity over infinity squared would be 1.Veret said:Whether or not you guys are right, you don't need any of that knowledge to answer this one. Say we assume that there really is an infinitely large universe containing an infinite number of stars, all of which have been burning for all time--as the original paradox implies. The amount of light at any point decreases proportionally to the square of the distance (1/d[sup]2[/sup]). Even if there are an infinite number of stars, they will be, on average, infinitely far away. So we multiply this luminosity per star (1/(infinity)[sup]2[/sup]) by the number of stars (infinity) and get infinity over infinity[sup]2[/sup]. So long as you're not afraid of dividing infinity by itself, you can simplify that expression to 1/infinity, also known as zero. Hence, nighttime.

Maze1125 said:Infinity/infinity is not necessarily 1. It can be any number, including 0 and infinity itself.
And here we see the delightfully screwed up mathematics that come into play when you try to use infinite numbers in your algebra. Thing is, in an expression like inf/(inf[sup]2[/sup]), any number involved is either infinite, in which case it dominates the equation, or finite, in which case it might as well not even be there.[footnote]Or, if infinity is raised to a power (e.g. inf[sup]2[/sup]), then that term becomes the important one and all the other infinities are irrelevant.[/footnote] With that sort of simplification, you can say an expression "works out to about three, give or take six billion" and still be accurate.Redingold said:Actually, since infinity squared equals infinity, infinity over infinity squared would be 1.
There are a finite number of stars within a finite distance of Earth, but an infinite number that are infinitely far away. So it's actually inf[sup]2[/sup]/inf, which means the average distance is still infinite.Maze1125 said:Further, the mean distance away is not necessarily infinity, as the mean distance would be the sum of all the distances, divided by the number of stars. Which would be infinity/infinity.
So if infinity/infinity was 1, your mean distance would be 1 too.
The answer of zero I gave is most certainly wrong, yes. But remember that whole "give or take six billion" thing I did? I was only trying to prove that we are not being constantly baked by an infinite amount of stellar luminosity; all that matters is that I got an answer that was not infinity.Maze1125 said:And you can tell your result is wrong without mathematics anyway, as it gives an answer of 0, which would mean no light reached the Earth at all, which is clearly false as we can see some stars at night.
