My basic understanding of the CMB tells me that this 'wall of radiation' is currently the furthest electromagnetic wave from our position that we can detect. Through relativity we know that objects far away are seen in an 'older' state due to the emitted photons taking time to reach our measuring tools.
My understanding is that as there is effectively no centre of the universe, so the CMB was emitted from every point of the universe roughly 300 thousand years after the Big Bang as it cooled and expanded. I understand that the CMB we detect today has travelled roughly 47 billion light years to reach us (EDIT: unsure on figures) and therefore we are effectively seeing the universe roughly 13.8 billion years ago.
My questions are as follows. Suppose we are an observer in a hypothetical Galaxy X located 47 billion light years (EDIT: unsure on figures) from the Milky Way Galaxy. We launch our own microwave detecting satellite and survey our sky.
If there is no centre or starting point of the universe, when we look out far enough from Galaxy X do we see the same CMB beginnings that an observer in the Milky Way Galaxy sees?
When looking back towards the Milky Way Galaxy do we simply see CMB from roughly 13.8 billion years ago?
If everywhere is effectively the centre of the universe, I would expect an observer from every Galaxy in the universe to see the same CMB?
If there was an observer at every point of the universe, would we expect them to all see the same CMB when looking out with microwave measuring equipment?
Would they all argue that they are in the present time and every direction they observe at far enough distances are further back in time?
Am I on the 'right track' here?
Cheers,
Dan.
EDIT: unsure on figures. Questions still stand to be answered.
