The photons the sun emits as sunlight are born in the center of the sun and take 10,000 years to reach the surface, be emitted and then another 8 minutes to reach the earth.
There are so many of them there is no detectable space between them, to say they are pervasive pales in comparison to reality.
Many of the things we see are lit by photons bouncing off objects, ending their long journey by entering our Iris which results in our neuro transmitters communicating, what we all thought or experience.
Just think about that next time you are trying to decide weather or not to go watch the sunset. Those photons are waiting for you to give their 10,000 year journey purpose. Do you really want those photons to go to waste? Its your civic duty.
