We CANNOT see from one material universe to another. Srimad Bhagavatam Canto 5 Chapter 21 Text 11, Purport.

Srila Prabhupada - ''Each universe is covered by various layers of material elements (The 7 layers of the outer surrounding Brahmanda that incases each universe), and therefore although the universes are clustered together -

We CANNOT see from one universe to another.

In other words, whatever we see is within this one universe. In each universe there is one Lord Brahmā, and there are other demigods on other planets, but there is only one sun''.- Srimad Bhagavatam Canto 5 Chapter 21 Text 11, Purport.
