When the Bubble Bursts

The big-bang blew out this universe  
from bubblegum blown by some deity,  
huge non-existent lips were pursed  
then blew and blew with alacrity,  
then quarks and electrons came to be  
from its spittle as the bubble grew  
but the thing which is chewing on me  
what did Newton's Third Law get to do?  
   
Coz, I've heard there's no front nor obverse,  
or insides to a singularity,  
nothing for the Third to push in reverse    
no equal and opposite reaction, see?  
But still something blows and with glee  
thick as a Plank I haven't a clue,  
my head aches now, that's reality,  
out of nothing a universe spewed?  
   
When I was a kid,  mother got terse  
and berated me if I chewed chewy,    
she'd not shout nor stamp and not curse  
just say " mucky stuff, waste o' money."  
But she got a laugh thought it funny    
when inevitably my bubble blew,  
and left my face gummed and clarty  
but if this bubble bursts, I guess we're screwed...
