MyOwnBestCritic Paradoxes are fun biggrin For example, the opposite of a correct statement is a false statement. But the opposite of a truth can be another truth. I know that I know nothing. Deep down, he's very shallow. If you went back in time and killed your gradfather (before your dad/mom was born), then would you exist? Logic says no. But then who killed your grandfather? Nobody. So he isn't dead. So you still exist, and you still kill him. But... Hehe, Microsoft Works. Although I like Microsoft, it's still tremendously funny smile
Oh, now this is a sci-fi thread, eh?
There are several theories for that, none of which I will go into now.
Especially since it's HIGHLY unlikely that reverse time travel is possible.

One example paradox is Curry's Paradox. A natural language version of Curry's paradox might be the following sentence:
If this sentence is true, then Santa Claus exists. Suppose the sentence is true. Then, since it is true, and it says that if it's true, Santa Claus exists, we can conclude that Santa Claus exists. This step follows from the technique of natural deduction known as conditional derivation. So if the sentence is true, then Santa Claus exists — which is exactly what the sentence states. Therefore the sentence is true and Santa Claus must exist. Since it is evident that any claim could be "proven" in this manner, there is a paradox.
Oxymoron comes from the Greek oxy(Sharp) and moros(dull) meaning "that which is sharp is dull," thereby designating and also exhibiting an opposition between two adjectives which serve as predicates for one subject.
Here are some examples. civil libertarian anecdotal evidence inductive logic Larger half Pretty ugly deafening silence Jumbo shrimp
Another paradox presented in Robert Louis Stevenson's short story, The Bottle Imp, involves a bottle with an imp inside that grants the owner's wishes as long as he owns it. Of course, there is a catch - the bottle must be sold at a loss, i.e. for less than its owner originally paid, or else it will simply return to him. The currency used in the transaction must also be in coin (not paper currency or check). Another condition of the sale is that all conditions and rules of purchase and ownership must be fully disclosed and understood by the potential buyer. If an owner of the bottle dies without having sold it in the prescribed manner, that person's soul will be tormented for eternity. The premise of the story creates a paradox: what is the lowest price the bottle can be sold for? Clearly buying it for one cent would make it impossible for it to be sold at a loss. It follows that this makes it impossible to be sold for two cents if it is later to be sold on for a loss and the buyer is given full disclosure of the details of the transaction and its ramifications. The same argument makes it impossible to be sold for three cents, or four cents, or indeed any finite amount.

Masamune no Hi Another paradox presented in Robert Louis Stevenson's short story, The Bottle Imp, involves a bottle with an imp inside that grants the owner's wishes as long as he owns it. Of course, there is a catch - the bottle must be sold at a loss, i.e. for less than its owner originally paid, or else it will simply return to him. The currency used in the transaction must also be in coin (not paper currency or check). Another condition of the sale is that all conditions and rules of purchase and ownership must be fully disclosed and understood by the potential buyer. If an owner of the bottle dies without having sold it in the prescribed manner, that person's soul will be tormented for eternity. The premise of the story creates a paradox: what is the lowest price the bottle can be sold for? Clearly buying it for one cent would make it impossible for it to be sold at a loss. It follows that this makes it impossible to be sold for two cents if it is later to be sold on for a loss and the buyer is given full disclosure of the details of the transaction and its ramifications. The same argument makes it impossible to be sold for three cents, or four cents, or indeed any finite amount. Actually it would be possible to sell the bottle indefinitely given the right circumstances. What one man takes as a loss, another man could see as worth more, and as such, something sold for as little as one cent could be sold again at a higher price and still be considered a loss. That's not even taking into account currency exchange rates and inflation.
