The Great Dying

This sun with its attendant train  
of rocks orbits this Galaxy,  
this done twenty times in this vein  
since cold and small science tells me.  
Two hundred million years will see  
it again in this space as it soars  
falling ever majestically  
towards the milky way heart's core.  
   
Did it pass this way through strange rays  
the last time round, we cannot see,  
those years ago but same pathway  
and as it passed a killing spree  
occured on land, oceans, air and seas,  
beasts, fish, insects, birds even spores  
perished and those are never seen  
but that made way for, dinosaurs.  
   
Is this sun, again, with its chain  
of planets bound through miasme,  
a filthy smog reducing brains  
to accept freedom-killing sprees?  
I speak only of what I see  
I hear roaring of dinosaurs  
crushing folk, raped democracy,  
tyrannized by Tyrannosaurs.
