.
Only necessary to a deeply flawed and failed model.
The “necessity” ends when one accepts that our universe is decidedly bounded, not unbounded.
The prophecies WRT the end of time make it clear that the universe is is a small and expendable feature of the realm of the Father, and scheduled to depart:
Revelation 20:
11. And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.
