Millions of years old
In the dead of night, when we gaze up at the sea of stars above, what we are seeing is light, tens of millions of years old. It travels millions of light years across the universe, until it's finally absorbed by our optic centers. Now imagine what kind of insubstantial, deep space photons this light is carrying. Light that has traveled across the galaxy. Light that could be as old as the dinosaurs. Light that carries unknown properties, in minute amounts. Light that enters into our eye, into our brain, into our mind. Now imagine that you sit in a field, or some other area where the amount of light spilling from the urban landscape is at a minimum. You're out in the forest somewhere, far away from civilization. Its just you and the stars. Now imagine you lay in this field all night, not sleeping, but staring up at the stars. Now imagine you have a tent, and you sleep all day, and each night you gaze at the heavens above, absorbing the ancient light into your retina. Eventually, the cosmic rays will cause some kind of transformation. Right? The question is, how long will it take. How long will it take before the cosmic rays from the far reaches of the galaxy, carrying alien photons, change the structure of your brain, re-shaping your frontal lobe, causing you to develop incredible psychic powers. Imagine being able to control people with your mind! Imagine the power of crushing a person's heart with just a thought! Imagine what it means to be a true god of the universe! Feel the energy of this dimension and the next course through your veins!
