They are floating there. Somewhere. Sometimes. Some Times. Some Times not. It depends on the vector
, you know? Back and forth they travel, living happily in the realm of string theory and n-dimensional planes. If you live in n dimensions things happening in the fourth just become another object, like a pork pie within our 3 lousy dimensions.
Sometimes some times actually look quite tasty. The first time Alexander the Great killed one of his puppies. Or the time when Adolf Hitler fell in love with that nice jewish girl from next door in Vienna. Then they feast on these, like we feast on a pork pie.
And just like the consumed pork pie, a timelunch leaves no traces.
Just some abdominal discomfort and a new black hole.
