Laser-tracking the Milky Way over 13,803 foot Mauna Kea on the Big Island. Lasers allow the adaptive optics of the radio telescopes to remove the blurring effect of the earth's atmosphere. And they look really cool. And they make me wonder. Light years from now will someone on a distant planet be tracking these lasers as they arrive from the long-vanished Earth?
Got to be careful sending lasers into space. Might end up with something like what happened in the movie Battleship.
