My opinion about this is its common bullshit. People are trying to make the world end. Its a kind of abstract suicide, because life sucks and they can’t figure out how to access its beauty – so they think its supposed to end.
Its not supposed to end. And even when it ends it just restarts. Thats the Vedic / Upanishadic / Puranic view. Time is eternal, it has no beginning or end. What appears to be its beginning is merely a cyclic point.
All this apocalypse stuff is a mid-east cult leftover.
