In this modern age, we often take the stability of our world for granted. However, an academic revelation suggests that we are in the midst of a change so drastic that it feels like the ground is shifting beneath our feet. Well, at least the ground 3,220 miles beneath our feet, in the Earth’s inner … Read more
One of the major questions that has occupied Earth scientists over the past decade is, “What’s going on down there?” Beneath your feet, some 3,400 miles deep, lies the Earth’s inner core. It’s nearly the size of the moon, as hot as the surface of the sun, and helps maintain the planet’s magnetic field, which … Read more
The experiment was depicted by drawing an interferometric scheme of Sagnac fibers in a magnifying inset, starting from a local position (Vienna, Austria) of the rotating Earth. Two indistinguishable photons impinge on a beam splitter cube, entanglement occurs between them and then they are coupled in the fiber interferometer. Credit: Marco Di Vita A quantum … Read more
A group of physicists were able to make a measurement of the Earth’s rotation using photons – the particles of light – and experienced a strange quantum phenomenon called entanglement. This allows them to increase the accuracy of the measurement a thousandfold, and it can be used to investigate questions in fundamental physics. You may … Read more

The main technique Mistele used in his research, gravitational lensing, is a phenomenon predicted by Einstein’s general theory of relativity. As part of the research, Mistele plotted the so-called Tully-Fisher relationship on a map to highlight the empirical relationship between a galaxy’s visible mass and its rotation rate. In a discovery that challenges conventional understanding … Read more

LOS ANGELES — According to new research, Earth’s inner core, a massive iron sphere deep within our planet, has slowed its rotation. Scientists at the University of Southern California say their discovery challenges previous views about the behavior of the inner core and raises intriguing questions about its influence on Earth’s dynamics. It has long … Read more
