"t", "x", "y" and "z" have nothing whatever to do with the present. 
They are all factors relating to the past. 

There is not one event in this universe that directly links the 
present beyond point size. The relationship between everything can 
only be realized in time. I'm just as much in your past as I am in 
your future. You are just as much in my past as you are in my 
future. But we are absolutely unrelated in the present. 
**ABSOLUTELY**. 

The present is an instantaneous event throughout the entire universe. 
How could it possibly be otherwise? How can "now" not be "now"? 

According to the rules of the big bang theory, if I wave my hand 
about now, eventually I will see myself in the past waving my hand 
about exactly as I'm doing now. The scenario is of course a fairy 
tale, but not so the absolute character of now. 

The whole concept of simultaneity is postulated, apparently as a 
prop for SR. It, along with SR, are clearly falsified by the fact 
that the present is an ongoing instantaneous event. Do you perhaps 
have some strange notion that the present is static? 

I would suggest a visit to the home of the zero origin concept. But 
I don't think it would do much good while you persist in picturing 
the universe from the rather weird astral plane that physics seems 
to be using as a launch-pad to reality. That base was once 
justifiable. But not any more.
