It's Official: We Were WRONG About the Big Bang

The name "Universe" was a wrong term, as it limits your actual perspective. More conclusive name would be the "System of Nature". Your actual perspective is infinite (you will find out eventually). 
Time doesn't exist in the Infinity (of nothingness), as infinity is eternal (always there). Infinity is a logical fact.
Mass resides inside vacuum. Mass needs vacuum to reside or exist, but vacuum doesn't need mass for its existence. Vacuum is the actual realm and infinite.
At virtual particle level, mass & vacuum are interrelated, as every bigger virtual rotation (of mass) resolves into a smaller virtual rotation inside it. If your technology allowed, it would end up in vacuum phase. The virtual mass is displaced vacuum, for instance, you. This is how mass & vacuum are interrelated.
