X,Y,Z,T

I'm probably wrong and it won't be the first time... X,Y,Z,T is the mathematical form of representing the space-time continuum.
That is the 3 dimensions with time as the fourth dimension.

What I am hoping to come up with in this thread is a universal time zone greeting for the web.
Instead of saying, "Good Morning" or the generic, "Good Day." the designer in me want to play with it, but my education level is that of less then quantitative.

I thought perhaps an anagram, with the noun xaxis or xaxes (plural) as a start, but the stringing of the additional words to form a greeting is proving to be too much for this gal.

I'm quite happy to leave it at, "Good xyzt to you," but I thought that with the diverse selection of brains in this forum you might like to play with it too?

Cremmer and Julia and Sherk
used 11 for supergravity work
I was fine with just 4
or just a few more,
But let's not go totally berserk.

Then M-theory (Witten et al)
proved 11 was quite maximal
To do supergravity
using supersymmetry
You can't have a dozen at all

But that's not the quest for gravity is dimension 5
I'm only asking for 4 as a way to say hi.
I don't need a dozen,
Of relativities cousins.
Would you stick to the topic this time?
