Hi guys, As you can probably tell this is my first post, so I thought I ask a question that I've had trouble getting my head round. I think I know the reason but I'm not a 100% certain. Why is it that we see the CMB radiation from every direction we look? I would really appreciate if someone could explain this to me, even better if there was a diagram to go along with it to help me understand our position in the universe. Thanks in advance.
