New theory explains how Earth’s inner core remains solid despite extreme heat
Even though it is hotter than the surface of the Sun, the crystallized iron core of the Earth remains solid. A new study from KTH Royal Institute of Technology may finally settle a longstanding debate over how that’s possible, as well as why seismic waves travel at higher speeds between the planet’s poles than through the equator.
U.S. Energy Secretary Visits KTH
A University of California Professor, the 1997 Nobel Physics Prize winner and President Barack Obama’s Secretary of Energy paid a visit to KTH on December 8 — all in one person. Spending an afternoon on campus, Dr. Steven Chu delivered a scientific address Thursday and met students in a lab at the AlbaNova Centre for Physics, Astronomy and Biotechnology.
