We Use Black Holes to Study Tectonic Plates

The video explains how Earth's crust is divided into tectonic plates that move due to magma currents. Researchers use quasars and Very Long Baseline Interferometry (VLBI) to track these movements. Quasars, distant and bright objects in space, help map continental shifts. VLBI, similar to sound localization, measures time delays in light reaching telescopes to determine their positions. This technique allows scientists to track tectonic plate movements, Earth's wobble, and rotation speed, enhancing our understanding of geophysics and Earth's inner layers.

What can researchers learn about the Earth's inner layers through the study of plate movements?
