World's best suggested paradox

[Krion_Vark]

How long will it take you to cross a crosswalk if with each step, you cut the distance you walked with the prior step by half?

well if we knew how big the initial step was, how long the cross-walk is and how long each step takes, you can work that out

The first step is half the crosswalk.

still never get there the first step would have to be over half to reach the desination

More than over half because the second step needs to be half of the first step but further than he remaining distance. You need roughly 3/4 of the crosswalk in the first step. Then half of 3/4 is still larger than 1/4.

Is 3/4 more than over half? yes. You just kept my argument alive with your argument.

10/0,5 = 20

That means...

If you have ten apples and then put those ten apples in half a pile you would get twenty apples!

What about the whole: "If God is omnipotent he can move anything,but he can also create an immovable object."

 

[Irony's Acolyte]

One fine day in the middle of the night, two dead men got up to fight, back to back they faced eachover, drew the swords and shot eachover.

best paradox story i know

"He sees!" said the mute man of the blind man to the deaf man who heard him.

Although technically neither of these including the whole "Everything I say is a lie." aren't paradoxs. They're just incorrect. A mute man wouldn't be able to speak. So either he's speaking, and thus not mute, or he isn't. If he's speaking then he's still speaking, if he isn't then he isn't. The "Everything I say is a lie" statement can easily be called a lie without a paradox, all just because you are lying now doesn't mean that you always lie.

And while they are not paradoxes, its still fun as hell to think about they're impossibility.

A true paradox would be if you went back in time and killed yourself, thus causing you to cease existing in the future (this theoritical event subscribes to the idea that you can change the past without creating new timeline). Since you no longer exist in the future, you can't kill yourself in the past which means that you now exist in the future to kill yourself in the past causing yourself to not exist in the future thus rendering... See what I'm getting at when I say paradox?

The mute man and the deaf man are telepathic.

Eh, I guess you could explain it that way. But we all know what I was talking about.

Stupid psychics poking holes in my logic...

The paradox of motion named 'Achilles And The Tortoise"

In the paradox of Achilles and the Tortoise, Achilles is in a footrace with the tortoise. Achilles allows the tortoise a head start of 100 metres. If we suppose that each racer starts running at some constant speed (one very fast and one very slow), then after some finite time, Achilles will have run 100 metres, bringing him to the tortoise's starting point. During this time, the tortoise has run a much shorter distance, say, 10 metres. It will then take Achilles some further time to run that distance, by which time the tortoise will have advanced farther; and then more time still to reach this third point, while the tortoise moves ahead. Thus, whenever Achilles reaches somewhere the tortoise has been, he still has farther to go. Therefore, because there are an infinite number of points Achilles must reach where the tortoise has already been, he can never overtake the tortoise

isnt that dependent on them moving at the same speed?

If a tree falls in the forest, and nobody is around to hear it Does it make a sound?

Answer: No
Ask yourself, What is sound?
Sound is basically vibrations cause by impact or movement (take a drum as a basic example). A drum stick hits the head of the drum, the whole thing vibrates air molecules around it. The vibrations (AKA sound waves), travel through the air at very high speeds. If a person is in the vicinity (presumably having a working ear) the ear will convert the vibration that reaches it into what we perceive as sound.

If nobody is around, then nothing is there to convert it into sound, therefor all you have are vibrations in the air, not "Sound". The way ear plugs block sound is by preventing the eardrum from receiving vibrations.

FUN FACT: However, it is possible to pick up vibrations in the ear drum despite deafness, or plugs etc, if the source of the vibrations is placed on the skin near the ear on the skull.

One mistake. You said nobody, not nothing. Animals don't count under nobody.

True... but I have reached the same result when I swap in "Nothing".
OR...
What if I count animals in the "Nobody" category.

You're in a car going at the speed of light. It is pitch black outside and then you turn on the headlights. Do you see anything?

You become energy at the speed of light. In essence you are light. So no. You're dead.

IF this sentence is true then it is false.

You're assuming it has to be true to be false. But it's actually a Square-Rectangle situation. It can be true and therefor false (a square is a rectangle) but it can be false without being true (a rectangle is not a square

I believe you may be mistaken in the understanding of the meaning behind my paradox.
I do not mean that when this sentence is related to something like Shape A and Shape B it means Shape A is Shape B but is not.

What I literally mean is the statement made in my sentence is true thenit is false.

Again I repeat, If this statement is true then it is false.
