Heard this in a movie I was watching and it made me go hmmmmm, When you look into a mirror you are not actually seeing yourself as you are that very second, what you are seeing is an image of yourself from a nanosecond earlier. It took me a moment to think it through but it makes sense if you think about the fact that it takes a fraction of a second for the image your eyes see to be recognized by your brain. Therefore the image of you in the mirror is actually an image of you from a nanosecond earlier... odd

Add to this the fact that light travels at 186,000 miles a second so the light reflected from the mirror has to travel from it to your eyes. This takes time. So yes u r seeing yourself as u were not as u are.

Here is another " useful" fact. People listening to a radio broadcast of a music programme actually hear the music before the live audience. The reason is that sound travels at approximately 700 miles per hour so if u r in the live audience the sound takes time to reach your ears. But if u r listening on the radio the sound travels at 700'ish to the microphone and the same speed from your radio to your ears but the bit in between, that is when the sound is being transmitted, sound travels at the speed of light.

i worked at edwards afb many years ago and a civilian was going for low level speed record
the flight surgeon asked him how far ahead off the ac he was looking in flight the pilot responded about a half a mile to a mile at 6 00 knots, the flight surgeon told him if he achieved his record which i think at the time was around 3000 mph he needed to be looking much farher ahead because that mile he was looking at was behind him when it reached the brain at that speed
