I have no relevent qualifications, so this may be a stupid question. Please go easy on me.
Some time ago I posted a question asking how it could be that the observable universe is 156 Billion light years across, when the Universe itself is only 14.5 Billion years old and nothing can travel faster the light. Of course the answer was 'Inflation'. When the 4 forces were unified into a single force, the early universe expanded much faster than the speed of light. Then presumably all the stars in the universe formed long after inflation had ceased.
Ok, so that explains how the universe came to be it's present size. But how is it possible that we can see objects which are so far away? How did light from stars at the edge of the observable universe travel here in order that we could see them? Surely it must be the case that if an object is 75 billion light years away, it must take 75 billion years for their light to reach us?
