The article mentions that the magnetic field of the earth is changing more rapidly. Why is that?
- tankenmate 5y agoIt goes through cycles naturally and from time to time the magnetic poles flip (it happens every few hundred thousand years). The magnetic field is largely created by the movement of molten iron and nickel in the earth's outer core. Wikipedia has a pretty good article on it.[0] [0] https://en.wikipedia.org/wiki/Earth's_magnetic_field https://en.wikipedia.org/wiki/Earth's_magnetic_field
- jcims 5y agoWhoa it looks like we're estimating it takes ~7000 years for it to complete the flip. https://www.nsf.gov/news/news_summ.jsp?cntn_id=100358 https://www.nsf.gov/news/news_summ.jsp?cntn_id=100358 Biology appears to survive it but I'm curious what happens to our digital ecosystem when we lose a portion of our protection against charged particles.
