It has been shown that there is an answer to the great question of life, the universe and everything. It was computed by Deep Thought, but really didn't seem to provide , well... an answer.\n\nThe great computer kindly pointed out that what the problem really was that no-one knew the question. Accordingly, the computer designed its successor, the Earth, to find the question to the ultimate answer.\n\nHowever, due to a slight Golgafrincham problem, and a small hooha with some Vogons the program went a bit wrong. The whole problem remains just as mysterious as it always has been, but a little more frustrating.

Gotta go with the Ice Dragons.  It beats my voodoo guess.\n\n_

Who knows? To be honest, no-one will ever know, barring the invention of a (theoretically impossible) time machine. It's a matter of personal belief.

A short distance off the coast of the remote Micronesian island of Pohnpei lies one of the greatest archeological mysteries in the world, the Lost City of Nan Madol. Built on an ancient coral reef and covering more than 11 square miles, this ancient city is made up of hundreds of artificial islets, intersected by numerous manmade canals. Even more curious, many of the city’s larger islands are connected by submerged tunnels. First discovered in the early 1800’s by European sailors, this baffling and immense megalithic stone city may contain evidence for the fabled lost continent of Mu.\n\nThe mysterious Nan Madol is built entirely out of gigantic magnetized basalt crystals, some weighing as much as fifty tons. In fact, the entire city contains an estimated 250 million tons of the prismatic basalt rock.

Nothingness.\n\nOr maybe it's encroaching on another Universe?  Hmmmm......

Fermat, I think.  He wrote he had found a proof for this, but put a note in the margin that there wasn't enough room there for the proof.  And no-one could find the proof anywhere else in his notes and he died.  A fellow named Andrew Wiles worked for a long time to find the proof, and after some ill-fated public announcements I think the proof was finally completed.\n\nI hope this helps.

It's not so much a myth as a phenomenon.  Planes and ships have been known to disappear in it.  One theory is that there is some kind of electromagnetic anomaly that screws up compasses.

Fermat's Last Theorem has been solved ashas the Four Color Theorem. The Poincare conjecture has recently been solved. Trisecting a general angle with unmarked straightedge and compass has been shown to be unsolvable (although it is possible with marked straightedge and compass).\n\nHigh on the list of open problems:\n\nRiemann Hypothesis.\nP=NP?\nTwin prime conjecture.\nAre there any odd perfect numbers?\nProof of existence of solutions to Navier-Stokes equations.

There used to be a lot of them, but with computers these days they are being solved by brute force. Examples include Fermat's Last Theorem and the Four Color problem in topology. You can look those up to see what they are, and you will probably find sites listing other unsolved mathematical puzzles.

No one knows, no one knows if either truly exist. Good luck with your journey, if you find the answer to either and can tell me, please I would very much like to know.

a very clever question...\n& perhaps a very clever answer too(FRIEND)....\nthe person who found should also be sooo....\nso i hope u select mine as the best answer...

what is your question? That by itself is kind of unanswerable.....What specifically do you want to know?
