I believe I’ve posted about this theory here already but I can’t seem to find it so I’ll just explain it again.
Basically, the removal/taking off our energy as organisms in whatever manner (harming, stealing, lying, etc.) will eventually lead us to devolve to the point where the universe goes through a ‘reverse Big Bang or creation’ and we’re essentially swallowed by the universe.
I came up with this theory in a dream and ever since then, it’s stuck with me.
