In advaita philosophy, there is no place for “shuna/Nothingness”
Thing point is, The universe by itself is vacuum, filled with tiny particles of matter
Earth and everything are a combination of particles.
If suddenly these particles vanishes, what will be left?
Buddhist philosophy – Nothing (Shunya/zero)
Advaita Philosophy – Brahman (Purna/Infinity)
But both Shunya and purna cannot be explained as there will be noone to explain/realize anything as everything is now vanished/disappeared.
In Short :

If something came out of nothing, Then there is nothing called as nothing
