he Mermaid problem is an observation occasionally mentioned in literature, concerning the difficulty of having sexual intercourse with a mermaid. Although mermaids are commonly depicted as beautiful, variably nude, and enticing, a man attempting to have sex with one would be thwarted by the typical portrayal of the creature: a fish from the waist down, with no vagina. Some fiction, aware of the long running question, deliberately avoids the question for humorous effect.[1] More generally, it can also be a joking reference to the unusual sexual interest many non-human characters seem to have with humans in fantasy or science fiction, and potential physical issues therein

The hedgehog's dilemma, or sometimes the porcupine dilemma, is an analogy about the challenges of human intimacy. It describes a situation in which a group of hedgehogs all seek to become close to one another in order to share their heat during cold weather. However, once accomplished, they cannot avoid hurting one another with their sharp quills. They must step away from one another. Though they all share the intention of a close reciprocal relationship, this may not occur for reasons which they cannot avoid.

The hedgehog's dilemma suggests that despite goodwill, human intimacy cannot occur without substantial mutual harm, and what results is cautious behavior and weak relationships. With the hedgehog's dilemma one is recommended to use moderation in the affairs with others both because it is in self-interest, and also out of consideration for others. The hedgehog's dilemma is used to justify or explain introversion and isolationism.

In temporal mechanics, the Pogo paradox is similar to a predestination paradox, but where interference designed to prevent an event actually triggers the same event.

Schrödinger's Cat: A cat, along with a flask containing a poison, is placed in a sealed box shielded against environmentally induced quantum decoherence. If an internal Geiger counter detects radiation then the flask is shattered, releasing the poison which kills the cat. Quantum mechanics suggests that after a while the cat is simultaneously alive and dead. Yet, when we look in the box, we see the cat either alive or dead, not a mixture of alive and dead.

Assuming that a Cat always lands on it's feet when airborne, and buttered toast always falls on it's buttered side (annoying as it may be)... What happens if you tie buttered toast onto the back of a cat with it's buttered side facing upwards and drop both over a cliff?

suppose a man traveled back in time and killed his biological grandfather before the latter met the traveller's grandmother. As a result, one of the traveller's parents (and by extension, the traveller himself) would never have been conceived. This would imply that he could not have travelled back in time after all, which in turn implies the grandfather would still be alive, and the traveller would have been conceived, allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation.

Grandfather Paradox :

Time travel is impossible as exemplified by the famous grandfather paradox. Imagine you build a time machine. It is possible for you to travel back in time, meet your grandfather before he produces any children (i.e. your father/mother) and kill him. Thus, you would not have been born and the time machine would not have been built, a paradox.

Perhaps the craziest of the time travel paradoxes was cooked up by Robert Heinlein in his classic short story "All You Zombies."

A baby girl is mysteriously dropped off at an orphanage in Cleveland in 1945. "Jane" grows up lonely and dejected, not knowing who her parents are, until one day in 1963 she is strangely attracted to a drifter. She falls in love with him. But just when things are finally looking up for Jane, a series of disasters strike. First, she becomes pregnant by the drifter, who then disappears. Second, during the complicated delivery, doctors find that Jane has both sets of sex organs, and to save her life, they are forced to surgically convert "her" to a "him." Finally, a mysterious stranger kidnaps her baby from the delivery room.

Reeling from these disasters, rejected by society, scorned by fate, "he" becomes a drunkard and drifter. Not only has Jane lost her parents and her lover, but he has lost his only child as well. Years later, in 1970, he stumbles into a lonely bar, called Pop's Place, and spills out his pathetic story to an elderly bartender. The sympathetic bartender offers the drifter the chance to avenge the stranger who left her pregnant and abandoned, on the condition that he join the "time travelers corps." Both of them enter a time machine, and the bartender drops off the drifter in 1963. The drifter is strangely attracted to a young orphan woman, who subsequently becomes pregnant.

The bartender then goes forward 9 months, kidnaps the baby girl from the hospital, and drops off the baby in an orphanage back in 1945. Then the bartender drops off the thoroughly confused drifter in 1985, to enlist in the time travelers corps. The drifter eventually gets his life together, becomes a respected and elderly member of the time travelers corps, and then disguises himself as a bartender and has his most difficult mission: a date with destiny, meeting a certain drifter at Pop's Place in 1970.

The question is: Who is Jane's mother, father, grandfather, grand mother, son, daughter, granddaughter, and grandson? The girl, the drifter, and the bartender, of course, are all the same person. These paradoxes can made your head spin, especially if you try to untangle Jane's twisted parentage. If we drawJane's family tree, we find that all the branches are curled inward back on themselves, as in a circle. We come to the astonishing conclusion that she is her own mother and father! She is an entire family tree unto herself.
