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 vast expanse of the night sky, a canvas studded with countless stars, is about to reveal a rare and spectacular phenomenon. Brace yourself for a stellar light show as T Coronae Borealis, a seemingly inconspicuous star nestled in the Corona Borealis constellation, is on the verge of a dramatic nova explosion. T Coronae Borealis … Read more

The inner core began to decrease in speed around 2010 and moved more slowly than the Earth’s surface. Credit: USC A new study provides clear evidence that Earth’s inner core began slowing its speed around 2010. USC Scientists have discovered that the Earth’s inner core is slowing down relative to the Earth’s surface, a phenomenon … 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

Credit: CC0 Public domain About 2.5 billion years ago, free oxygen, or O2first began accumulating to meaningful levels in Earth’s atmosphere, paving the way for the emergence of complex life on our evolving planet. Scientists call this phenomenon the Great Oxidation Event, or GOE for short. But the initial accumulation of O2 on Earth was … Read more
