Thanks for all your really informative answers to does light accelerate I have another more interesting question.
For this consider the following crude analogy: Consider a perfectly spherical pin cushion about the size of a golf ball, it filled full of pins tightly packed together so much so that you can no longer see the pin cushion only the pins. Imagine this perfectly spherical pin cushion is suspended in the centre of a balloon , which itself is suspended inside a spherical hot air balloon, which is suspended is a sphere the size of the moon, which is suspended inside a sphere the size or earth , next the size of sun. Now extrapolate the pin lines outward until they touch the inner surface of each of the aforementioned. Because the do not expand as cone shaped but simply straight lines you end up with a very spikey pin cushion and as the pins get further away from the cushion the distance between the pins expands. In between the pins there is space with no pins.
Now consider a light source about the size of the pin cushion, we can calculate the amount of light emitted right (yes). So if each of the photons/stream of photons/light waves leaves the perfect spherical surface as they travel outward they will become more distant from each other. Ahaa I hear you cry but you must take into account the fact the light will leave the sphere at a multitude of angles. I have considered this and still think you would need an infinite number of photons (streams, waves) leaving at an infinite number of angles if you were to end up with a wall of light a trillion miles away . Where am I going wrong??
