But we aren't seeing light in the atmosphere. We are seeing the laser light at the moon's surface. |
In real time! Didn't you just say that we don't see the laser light at the moon's surface? Don't reply. |
I
will reply. No, I did not just say that. And no, we do not see it in real time. The laser light illuminates the reflector when it hits it, i.e. 1.3sec after being switched on. But we only see it 2.6sec after it is switched on. That is not real time, Dingbat.
