Thanks for the response Drakkith.
I figured something like his was possible, but like phinds says, the necessary accuracy would be ridiculous. Also, I assume the original signal would have to be extraordinarily powerful.
Here's my idea for how to line everything up: Send the...
Perhaps the total number of bounces could be just one: so the light signal forms a giant V in space, where one vertex is the Earth at time 0 and the other vertex is the Earth at time x, and at the angle is the satellite.
Aren't Voyager 1 and 2 still working on getting out of the solar system...
Well, imagine if someone put something there...
If I were to shine a light into space (a SUPER intense electromagnetic wave, possibly with information encoded in it), would it not travel in that direction at 3E8 m/s? If we point it at where the Earth will be at x years and point the light in...
Given a particular Earth latitude and longitude on a certain day (December 21, 2012), is it possible to know which direction to look into the starry sky to see future Earth (where it will be in exactly 1, 4, 9, whatever years)? If we know how Earth revolves around the sun and how the sun moves...
