Wow! I never thought that would make a difference. I always think of the "speed of light" as instantaneous.
Actually Southern Man the speed of light is far from instantaneous. It just depends on how big of a picture your little mind is capable of seeing.
When you looked out the window this morning and saw sunlight, it took 8 minutes for that light to get from the sun to the earth.
One of the many communications difficulties that NASA has with their space probes is the fact that they have no real time data and ways of relaying commands instantly based on that real time data.
Lets take for instance communications with the Mars Rovers Spirit & Opporitunity. A command to drive is given for a given distance that they have plotted as safe. The signal to do so is sent from Earth and takes 4 minutes to travel to Mars. Data sent back showing the consequences of that move take 4 minutes to return to Earth.
Imagine driving a radio control model truck around your yard with an 8 minute lag in knowing where it is and what it's doing!
Let's move out a little further to Saturn and the Cassini probe. It has a one way time of 1 hour and 14 minutes.
Let's move out a little further to the Voyager 1 probe which is the furthest man made object. A signal from Earth to Voyager 1 takes 14 hours for a one way trip.
Alpha Centauri the closest star to our solar system is 4.37 light years away from us. That would be the distance light travels in 4.37 years....
Lets look out even further to what the Hubble Space Telescope is seeing. Using Gravitational Lensing where the telescope uses the gravity of groups of distant galaxies to pull the light from galaxies even more distant into view are looking at light that has been traveling so long that it left very near the creation of the universe and only today is reaching us.
How big is your mind?
