After reading the wikipedia article and looking at many other threads on this forum I am still having a hard time understanding the difference between the Observable universe and the entire universe...
Why is the entire universe not observable to us?
The Big Bang happened 13.8 billion years ago. At that point in time, the distance between us and everything else was 0. The universe has been expanding ever since. But we can observe the cosmic microwave background which is the remnants of the big bang and the time when everything was densely packed together. Therefore I do not understand how there can be anything we can't observe if we can observe the beginning of the universe itself?
Please can someone help?
