An Untimely Rebus For Your Puzzlement

Now with eye-popping graphics! (Hey, it's my first rebus.)
Text version:
$$\begin{matrix} light-speed & & & & here\\ & & ? & & \\ \end{matrix}$$

• Is the ? part of the rebus? – boboquack Jan 16 '17 at 22:19
• @boboquack Yes, the question mark is a part of the rebus. Sorry for the slow response. Posted just before going to bed. – Hugh Meyers Jan 17 '17 at 5:09
• untimely, hmm – Strawberry Jan 17 '17 at 10:40

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!

• Great! You might say the second puzzle rose from the ashes of the first ;) – Hugh Meyers Jan 18 '17 at 9:26

Could it be

CLEFT?

Explanation:

Light speed is usually denoted by $c$, and the fact that "Here" is on the right indicates that that's our frame of reference, i.e. c is on the left, giving "cleft".

• Nice, but the question mark is at the heart of the solution, I'm afraid. – Hugh Meyers Jan 17 '17 at 19:26
• @HughMeyers Now I get what you meant by "at the heart of the solution". :) – Ankoganit Jan 18 '17 at 15:12
• @Ankoganit ... as in "slightly to the left of center". ;) – Hugh Meyers Jan 18 '17 at 15:16
• @HughMeyers You might say it filled the CLEFT in the middle of the solution ;-) – Rand al'Thor Jan 18 '17 at 15:17

Is it -

Future .(as time-travel is there)--thinking about future--

As-

"Here" is front of "speed of light" , so you have crossed speed of light thus you are in traveling to future i.e time travel

Rayovac, a famous battery brand

Because

What is untimely light speed? Absent time its just distance, an infinite ray. A ray to here over a stick figure with an empty question? The ennui! It's a ray over a vacuous individual or, to stretch it, 'rayovac'.

Perhaps

Nothing to see here

From

speed of light $c$ = see
nothing between it and here

• Another good guess. The answer, however, is a single word. – Hugh Meyers Jan 17 '17 at 17:27
