Please help - I'm sure there's a simple answer to this question, so any explanation would be very welcome: If you looked out into the night sky with an ultrapowerful telescope, in principle you could see back to the Big Bang no matter which direction you pointed it (suppose for a moment that the big bang was accompanied by a sudden creation of a bit of light). How can a near singularity, with miniscule dimensions, be visible everywhere in the universe? PS I know no light was around at the big bang, but my point is that all points in the night sky might contain light from the universe when it was very small - how can this be? Also, if the universe started as nothing and then ‘exploded’, why did it have to start “small” and then “grow” – why not start at any size or shape? Why not start as a big ball, from whose inner surface materials emerge and then diffuse towards the centre? This would make sense of my first question.
