The Empty Trail

Same exposure they already looked through for the quiet kicks. Today they opened the higher window.

Two point eight four tonne-years. Up to about two hundred and seventy. One event still there: two hundred and forty-eight.

They do not claim a find. If it were the simple elastic thing the quieter recoils would have sat with it. They have one.

WIMP is a late mouth. Dark matter is a late mouth. I will not use those.

The leftover is the flash and the empty trail under it. Both sat still. Neither needs a name.
