It's take me a while to formulate the question I think I want to ask and this still might not be the right question to the puzzle in my head.
If the universe started out as a singularity and if the rate of expansion cannot exceed the speed of light and if light radiates out uniformly in all directions at a constant speed then why can we not every point in the whole universe all the way back to that singularity, why is there, to use a metaphor from the universe, an 'event horizon' beyond which we cannot see further back? It cannot be for example that light from any object, no matter how distant, would be 'only just reaching us'. Surely the light from that distant object would always have been radiating out at the speed of light and the light wave would've expanded universally to fill the entire physical cosmos in all places and at all times. If our existence comes subsequent to that event then sury we would be 'born into' that light wave and thus all things should be equally visible to us subject to our instruments being sensitive enough to detect them.
Big question for a Monday morning I know but I'm waiting for a consultants appointment about my broken shoulder so I have nothing else to do apart from ruminate on such matters!
