Another discovery by a Michigan Technological University researcher could send shockwaves across the world of earth science.
Aleksey Smirnov, assistant professor of geophysics, with colleagues from the University of Rochester and Yale University, has discovered that the earth’s inner core could actually be at least 1.2 billion years older than previously thought.
“It’s a big deal to researchers in this basic science who thought the earth’s core was much younger, so to speak,” Smirnov says of his paper in the journal Physics of the Earth and Planetary Interiors. “They won’t be happy with it.”
