So, before this happens (if it does) we wouldn't see any major changes worldwide like volcanoes erupting? Earth quakes nearly world wide at the same time? Extreme weather changes worldwide at the same time? Earth basically cracking open world wide?

And I mean much worse than what every country/continent has endured...

Or does it just not work like that?

I'd be confused if we didn't see any major, huge changes before or at least at the start of all this happening... think about it... it's the earth flipping opposite sides...

I would guess the equator would go through some extreme changes/ chaos and the ice caps completely changing at least...

Just my 2 cents worth... (just trying to imagine would this would be like)
