- 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.
Do we see:
- the light bulb in real time?
- the reflection of light bulb off the mirror in real time?
- nothing in real time? |
How can this be tested when the mirror, the light bulb, and the observer are so close to each other. It presents the same problem as the example of seeing the spot on the moon. |
Why don't you actually answer the question and then we'll concern ourselves over how this was tested.
