The inherent problem is that the universe has been transparent for a limited amount of time. Since this time the light from this era has been travelling in all kinds of directions, some of it in ours.
We can only see the light that has had time to reach us. Everything that is farther away than about a dozen billion lightyears is not visible.
Technically new stuff is always becoming visible to use, the visible universe expands naturally as new light reaches us.
Of course, the stuff is now farther away since the universe is expanding and at some point the expansion will likely overtake the speed of light and over some distance may have, which means beyond some distance we will never be able to see or know.
What is beyond the visible universe is quite unknown. We can't see it.
