Is there any universal truth?
You are thinking too much.
Matter exists. I'm not saying it will always, or that it always has existed but it does in fact exist.
Quit trying to be so deep and get some common sense.
Being deep is over rated.
I see that as the easy rout, anyone can be like: "oh, well how do you know anything exists, what really matters....."
Get real and do what is best for your future.
Side: Being deep is over rated
If you argue on that level then their is no possibility of any universal truth. Time cannot be used to argue universality because you cannot argue that time is universal either. Do you understand what I mean? I sometimes have problems being eloquent with my explanations.

Is your question the antithesis of: Is there any universal falsity?
The existence of a universal truth? It depends what you are denoting or connoting in your usage of the term "universal truth".
Are you using the term "universal" as contrary to "particular" truth?
All men die; this is true, universally. There is no exception that one man will not die.
Side: Uncertainty of authors use
Yes, you have pretty much hit the nail on the head for a definition. But can you say with full vindication that every man will die? You never know what things are unknown? I'm not necessarily saying your right or wrong, I am just stating arguments to keep people thinking. Its a hard question no person has been able to answer for thousands of years, and most likely will never be able to answer, but it is fun to ponder.
Side: Still unanswered
The statement: all men die, is a self-evident statement. The statement needs no proof because its truth is obvious. Now, lets convert that statement into a self-evident proposition; all men are mortal. The proposition is an axiom, meaning its truth is obvious and no proof is necessary.
The vindicability of the proposition is as obvious as the axiom itself. Any argument that contradicts the axiom is an argumentum ad speculum and is not vindicable; for the argument of speculation is absent any evidence that is axiomatic.
The proposition will remain an axiom until a contradictory axiom is revealed. That is a universal truth.
The contradiction being of course; Some men are mortal.
Perhaps, but I nor any other man or woman shall live long enough to verify that possibility. The mortal man can not bare witness of immortality. The mortal man can certainly bare witness of the long-lived man, but never the immortal man.
If there is a man among us who shall never die, the same could not truthfully be called a man.
Lets start with this. To assert that something is true is to say that something is definite, unchanging, or completely self-consistant. So, to ask the question is there a universal truth is really asking is there something in the universe that is true. To answer this question we must not accept any bias whether it is religious or none religious. So i our assumtion is that anything is possible but then if anything is possible we also assume the possiblity that nothing is possible. Ultimately this statement cannot be true because if anything is possible that would mean it is possible for something and nothing to be possible at the same time which clearly contradict the whole idea in its' self. The answer is that only somethings are possible because nothing cannot exist no matter how you try to make sense of the idea its' just simply impossible. So there you have the final answer to your question. Only something can exist and nothing cannot that is a universal truth. So universal truths do exist.
Side: Truth is universal
