To illustrate this further, we now demonstrate how equation (4) leads to entanglement in a version of Feynman’s experiment. Two spherical mass distributions, each with total mass M and radius R, are prepared in a quantum superposition of two locations. This could be achieved by, for example, implementing matter-wave beam splitters6, manipulating potentials32 or exploiting internal degrees of freedom, such …

Elaine Hendrix brought the Dancing With the Stars ballroom to its knees on Wicked night. The Parent Trap star and her pro partner Alan Bersten earned among the lowest scores last week after their “Dedication Night” foxtrot for Hendrix’s bestie (and fellow Parent Trap star) Lisa Ann Walter. But Hendrix was able to rebound in a major way, with the pressure …

Earth carries an invisible ocean “water level” called the geoid. If only gravity and rotation shaped the oceans, the surface would match that geoid everywhere. However, south of India, the geoid sinks sharply. At the center of this sunken feature, the geoid lies about 330 feet (100 meters) below the global average, a dramatic signal known as the Indian Ocean …

This week’s science news was bursting with mind-blowing astronomical observations, led by new discoveries about the origins of the comet 3I/ATLAS. The comet, an interstellar interloper from far beyond our solar system, was first spotted in late June. Now, scientists are finally closing in on its age and where it came from. They discovered it likely originated in the far …

A good …

Satellites detected a strange gravity signal off the coast of Africa nearly 20 years ago, suggesting something unusual had happened deep within the planet to distort its gravitational field, according to a recent study. The large gravitational anomaly lasted for about two years over the eastern Atlantic Ocean. It peaked in January 2007, the same month Steve Jobs announced the …

Researchers looking through data from NASA and the German Aerospace Center (DLR)’s Gravity Recovery and Climate Experiment (GRACE) have found an odd gravity anomaly over the Atlantic Ocean. Attempting to find the cause of the anomaly, the team found it may be associated with a “geomagnetic jerk” detected around the world. There is still plenty to learn about the Earth’s …

In 2007, something strange happened over the eastern Atlantic Ocean. According to satellites orbiting Earth, our planet’s gravity field developed a continent-scale anomaly before subsiding to its original state. The odd event, undetectable to humans on the surface, has only just been discovered in data collected by gravity-monitoring satellites – and the cause was a tremendous redistribution of mass far …
