From what I understand, the light from CMB that we can observe is the result of the last scattering from the big bang which happened 380,000 years prior to the pattern we can see.
While it seems that the CMB is the limit of our observable universe, I'm understanding that there this isn't the limit to the whole universe. Meaning there is still space from when the CMB pattern was formed and the distance that the universe has expanded out from the origin of the big bang. Is there any way of knowing if this region of space is still active in some scale to the creation energy that the big bang produced but being so far away that it isn't ever going to be observable to us given expansion and inflation?
