Riddles!
So I thought we could start a thread for all sorts of riddles, mysteries and paradoxies so we can all comfortly spend our nights thinking about them <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo--> Ones that have a certain answer and ones that really can't be answered will do just fine. Discuss on riddles and post some of your owns, but remember to give decent spoiler warnings before you tell everyone if you know the right answer.
Akhilleus and turtle
Akhilleus(ancient runner hero) and a turtle have a running competition. Akhilleus gives turtle ten meters of advance and then starts running. When Akhilleus gets to the position where turtle was when the race started, turtle has moved a little bit forward. When Akhilleus gets to this position, turtle has again moved forward just an inch. So Akhilleus can't ever catch the turtle.
I couldn't explain that very well but I think you got it or have at least heard it before <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

Tere was this guy, He owned a 4 story house, and his neighbor owned dog. So, he went to his neighbor as said: " I bet your dog 50 bucks that can't jump higher than my house!". Caurse his neighbor accepted and the guy with the dog won. How is this possible?
Akhilleus starts from point A and turtle starts from point B. When Akhilleus gets to point B turtle is already in point C, when Akhilleus gets to point C, turtle has gain advanced to point D etc.
So Akhilleus can never pass the turtle because it's always 0,00000000000000000000000000000001 mm further, got it? <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->
you break it even if you name it.

This sounds a lot like a mathematical paradox I heard once. Here goes:
In order to get from point A to point B, you must first travel half way between the two. To get from this point to B, you must again move halfway between the two. Repeat this endlessly because there's always a midway point between any two points. So mathematically, if we set A to be at x=0 and B at x=1, the first midway point would be at x=0.5 then halfway between that and B would be x=0.75, etc etc. Well, according to this it would always be impossible to get to B from A because you'd always be moving halfway there. This can be generalized to state that you can never actually get anywhere because you must always go halfway first, and there's always another halfway point. Well, we know this isn't true, because we can go from point A to B in real life easily. So the paradox is that mathematically you can never get anywhere, while in reality you can.
I hope that made sense to someone besides me. <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->
You cross the void into the hole instantly, but from outside you take infinity to do so.
I could explain this principle a little easier if it wasn't 3:30am...
An infinite circle is therefore... a straight line!
... if Achilles stopped and took a pause everytime he caught up with the turtle, yes, but Achilles wouldn't do that, would he? I feel a strong urge to tell you how weak that riddle was, but I won't. I refuse!

We are very little creatures; all of us with different features. One of us in glass is set; one of us you'll find in a jet. Another you may see in tin, and the fourth is boxed within. If the fifth you should pursue, in can never fly from you. What are we?

the letter M... duh...
There's a master key. A master key opens every door in the school.
Every lock has only one key that it can be opened with.
So, to open one door, the key for the door and the master key would have to match.
So, if you have any key to anything in the school, it can open everything.
<!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif'><!--endemo-->
I'll try saying that in a clearer way:
The master key opens every door in the school.
Every door in the school has only one key able to open it, that key being the master key.
If you have a key that can open a door in the school, it's the master key. Therefore, you can open anything in the school.
Correct me if I'm wrong.
"Although my cow is dead I continue to beat her. What a racket she makes!"
"He caught it in the woods and brought it home because he couldn't find it. He searched for it for a long time and when he finally found it, he threw it away."
Scinet: no idea O_o
Maybe the cow has been gold plated and hitting it makes a lot of noise, so he hits it more o_O
and for that woods thing, I'm sure it's something like hope. I can't think right now, need to sleep. I'll think about it some other time <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
You are standing in a room with 2 doors. One guard is stationed at each door. One always tells the truth, one always lies, which is which, you do not know. One door will lead you to heaven, and one to hell. With just one question for one guard, how can you figure out which door leads to heaven?
And this one is just silly:
They untied the ropes, let the rope slide through their hands, and then retied the rope back up. Who died?
there are several answers to this riddle.
after thinking some more you never spicified whitch gaurd tells the trooth and wich one lies. i genraly think the trooth gaurd is at the heaven door and the untroothed guy is at the other.
(edit)I know i spelled truth wrong
take the other
or:
1) ask guard 1 what guard 2 would ans to this Q: "What door leads to heaven"
2) take the other
and yes, it teaches you how to solve simple logic problems like that (I wish it was all fun logic problems but it isn't and thus it aint nearly as fun)
it is knights and knaves exept esier b/c you can ask things other than yes/no Qs

As does one's mass. (no fancy charts here)
it was daytime. thats a personal favorite of mine.
about the mass goin to infinity, thats a common misconception, really only the energy required to accelerate you goes up and up and it is often portrayed for the sake of common sense as your mass, when in reality you will not become a gravitational force.

The answer to the cow riddle is a simple as "drum".
As for the woods thing, solving without googling/prior knowledge is appreciated.
Poor people have lots of it
