- the light bulb reflected off the glass plate in real time?
- the reflection of light bulb off the mirror in real time?
- nothing in real time?
Or, to make it more like Lessans' example, if we start with the light bulb off, then turn it on, when do we see the light bulb?
- instantly?
- after the light bulb reflects off the glass plate?
- after the light bulb reflects off the mirror?
- some other time that I can't figure out?

It's impossible to detect light before it arrives. That's like saying if the Sun was turned on and it took 8 minutes to reach Earth, we could detect the light before it arrives 8 minutes later. That's not what Lessans is saying. |
Did I say "detect light"? No I did not. In the example above you see a
reflection of the light bulb in the mirror.
We could break it down even simpler. Let's say you are looking at a light bulb in a mirror.
