Spacetime With Stuart Gary

SpaceTime Series 27 Episode 123*Discovery of a New Region within the Earth's CoreScientists have uncovered a doughnut-shaped region within Earth's molten liquid outer core, located at low latitudes parallel to the equator. This torus-like zone was detected due to seismic waves travelling slower through this area compared to the rest of the liquid outer core. The discovery, published in Science Advances, suggests that this region could be several hundred kilometres thick and contains a high concentration of light chemical elements, which may be affecting the seismic wave speeds. The findings provide new insights into the Earth's magnetic field and its potential future changes.*Fresh Questions about the True Origins of the Earth's MoonA new hypothesis challenges the widely accepted giant impact theory of the Moon's formation. The study proposes that the Moon was captured during a close encounter between the young Earth and a separate terrestrial binary planetary system. This theory could explain the Moon's curr
