Enigma

Toward LATER's  
Vast  
Perpetually empty  
receptacle of promise......  
 
ALL  
seamlessly  streams
It's visceral liquid  
Constantly disappearing  
NOW  
 
THEN?  
Experience flattened  
non-existant  
Yet strangely recordable  
to prove it happened  
Influential  
Yet infinitely less  
Than a split atom  
 
Which all begs an answer:
 
WHEN ?
