it takes 8 minutes to get here once it leaves the sun, the photons bounce around inside the sun for a minimum of years, and at most 50 million years before the escape from the inner sun.... That means the photons you take in through your eye to see the world are typically centuries or millennia old, which means the universe knew you would view the photons you do that long ago before you even existed... as we know viewing a photon entangles it... It's a real trip, I know... :)
