Believe me. I'm a liar.

This is a paradox!! Cannot be resolved. It is just like saying that "This sentence hass 3 misttakd."

The universe is everything that exists.  The opposite would be everything that doens't exist.  So, the opposite is nothing.

The universe is an indefinite entity.It is bounded by 'nothing' even in the strict sense of modern physics.

Imagining the world with no hypothetical situations is a hypothetical situation itself.  It's an impossible paradox.

Absoultue zero in terms of Kelvin is impossible to obtain because there can never be nothing

I agree. Every single emotion; every single scenario imaginable; both sides of the extreme and what lies in between will occur in this universe. In my opinion, anything is possible in this universe…ANYTHING! And I don’t think this universe has meaning without human ‘observation / awareness’ (consult ‘the observer effect’ in quantum physics + my question about the sound of tree falling in the forest).

Its pretty old, but its flawed. It is only a paradox if both exist.\n\nSince neither exists there is no paradox,  just a mental game for philosophers or something to get really worked up about when you are ratted in the pub.

Contradictory Premises. Conclusions are drawn from the interactions of premises: where two premises contradict each other, there can be no interaction and hence no conclusion. Similarly, if the definitions of two terms conflict with or exclude each other, then those two terms cannot be simultaneously ascribed to a single object or event. The classic example of contradictory premises is the question, "What will happen if an irresistible force meets an immovable object?" The problem here is that in a universe where an irresistible force has been defined to exist, there cannot also exist an immovable object, because then the force would not be irresistible. Conversely, if there is discovered or defined such an item as an immovable object, then by definition there can be no such thing as an irresistible force.\n\nThis fallacy's most popular appearance is in the form of a challenging question, because questions with contradictory premises are such brain teasers. In each case, though, no answer can be given because the premises cannot both be true.\n\n    * Into what shape of hole would a round square fit?\n    * If an object is all black and all white at the same time, what color is it?\n    * If an object is both stationary and traveling at an infinite rate of speed, how long will it take to meet itself?\n    * If God can do anything, can he make a stone so heavy that he cannot lift it?\n    * If God is all powerful, can he put himself out of existence and come back with twice the power he had before?

I think the hardest question ever asked was asked by a scientist.  This was the question, and it literally drove him insane thinking about it:  Two large metallic orbs are traveling towards each other on a collision course.  Both are indestructable, and nothing can divert them from their path in any way.  They can never stop moving on their path for any reason.  What would happen when they collide?  Neither can be moved from the path that they are traveling, they cannot be destroyed, and they can never stop moving.

LeAnne has a very good answer - however, I think the final frontier is to determine a Grand Unified Theory. With the solution to "everything", it wouldn't be much of a step further to explore parallel universe, different realities and worlds, time, the Big Bang, etc.\n\nI think the the Grand Unified Theory would give us the ability to explore, and answer, all questions regarding everything cosmological and would go a long way to answer some theological and philosophical questions.\n\nNo fear, however, I believe that humans, as a species, will self-destruct (and probably most other species on earth) before the GUT is developed.

This is Zeno's paradox... Possible resolutions include: (a) the universe is NOT actually continuous but composed of discrete quanta therefore any distance actually cannot be cut in half as anything other than a mental exercise, (b) calculus: if distance can be broken into infinitely subdivisible parcels, so can time.  The way that a distance is traversed is the same way that time is traversed and so... integrating over an infinite number of distance segments can be easily done with an infinite number of (infinitesimal) time intervals.

Without a doubt, although it's not an unsolvable paradox.\n\nThere are three options.  Either he tells the truth 100% of the time, lies 100% of the time, or mixes truth and lies.\n\nIf he tells the truth 100% of the time he can't make the statement he just made, as it'd be a lie.  If he lies 100% of the time, he can't tell you this, as it would be the truth.  So by elimination, he must tell lies some of the time and truth some of the time.

The two best answers to this paradox are basically one of logic and one of semantics, and they each say that the question doesn't make sense.\n\nThe answer using logic is that if such a thing as an irresistible force exists, then no object is immovable, and vice versa. It is logically impossible to have these two entities (a force that cannot be resisted and an object that cannot be moved by any force) in the same universe. \n\nThe answer using semantics is that if there is such a thing as an irresistible force, then the phrase immovable object is meaningless in that context, and vice versa, and the issue amounts to the same thing as asking, e.g., for a triangle that has four sides.
