watching space is not enough i need to be atomized by a supernova
i need to disperse and glow like a nebula
getting utterly destroyed by a gamma ray burst
violently have my matter reclaimed by the universe
in a few trillion years at most.
your first real shot is in about 400 4 billion years1 when andromeda collides with the milky way.
there's a non-zero chance that the solar system could be consumed by one of the supermassives involved.
if the supermassive doesn't get you, it's okay.
sol will eat the entire earth about that time anyway.2
