How the world will end

Some say the world may end in fire and ice 
some say it may end in waves of lava 
some say it may end in a fiery bang like the one that extinguished the dinosaurs 
some say we will never know how it ends 
I personally want eternal non existence 
No afterlife for me.... 
Hopefully not a violent death but an easy one 
A wave of euphoria at the idea of being nothing
