word - An Untimely Rebus For Your Puzzlement

Now with eye-popping graphics! (Hey, it's my first rebus.)
Text version:

$$\begin{matrix} light-speed & & & & here\\ & & ? & & \\ \end{matrix}$$

Answer

Could it be a

$corpse$

$c$ (speed of light) + $or$ (deciding which ?) + $pse$ (here = pse site)

The title: An untimely rebus may refer to

- late which has a meaning as a deceased body, or theatrical slang for ill-timed stage behaviour

- the same answer 'corpse' to one of the OP's questions posted the same day - very suspicious!
