We will be able to see closer to the beginning of the observable universe, or at least our universe.
Who knows how many others there may be?
"Who verily knows and who can here declare it, whence it was born and whence comes this creation? The Gods are later than this world's production. Who knows then whence it first came into being?
"He, the first origin of this creation, whether he formed it all or did not form it, whose eye controls this world in highest heaven, he verily knows it... or perhaps he knows not."
— Rig Veda 10:129
