The study of more than 100 earthquakes confirms that the sphere, roughly the size of the Moon, is reversing relative to the planet’s surface

    Don’t worry - there’s a documentary about when this happened last time. We can fix it again.

    The Core

        Yeah, it’s a bit of a guilty pleasure of mine.

    TL;DR it’s no cause for concern for now. Core is changing speed and direction in cycles.

      I wonder what kinds of affects this do have?

      It would find it bizar if there are no natural phenomena connected to it.

        Everything happening in the universe is “natural phenomena.” If we can’t explain it, we don’t have enough information.

        The geomagnetic field is weakening which is common during these kinds of episodes and eventually the polarity of the magnetic field will flip so that north becomes south and vice versa. During the transition though we are likely to go from our bipolar magnetic field to a quadrupolar magnetic field where the north and south poles can fluctuate between two different points each instead of the normal single point. You can see evidence of this occurring in geological history through Ignatius rock, as it cools from volcanic eruptions.

      Causing magnetic pole reversal?

        Not likely, considering the last few times it happened it didn’t. This is the first time it’s happened since the 1980s, not the first time it’s happened.

    Meanwhile, the mantle is tailgating the hell out of the core wishing it would move over to the right lane

    Wouldn’t it be more concerning if it was speeding up?

      Why would it be more concerning?

    In other news, the moon is getting farther away from the Earth, and the sun is expanding.
