The profundity of how light encodes reality is astounding. There are untold billions of light rays bouncing off you right now into every conceivable direction carrying your life and presence into the universe. You as a human being are radiating life that can be witnessed in any part of the universe, given that the light is able to reach that point unobstructed.

Even if the light that bounces off you is absorbed by the electrons in the walls, the walls themselves are recording your life. Everything is witness to your life here due to light.

We are alive for 80 to 100 years and we spend a considerable amount of time outside. Yes, not every moment can be recorded but an untold amount is.

Even beyond the red shift, the information is still there, and a couple of billion years of visible light is an impressive shelf life. More efficient than zip disks. ;)

This topic reminds me of the scene in Blade Runner where he is exploring the photograph on his computer, able to see around corners, etc. This is due to the properties of light, every photograph has embedded information for miles around the taken perspective due to the light that is bouncing off everything. I am sure one day soon we will have technology that can explore the information encoded in light that would allow us to look around corners in photographs.
