The Earth's center is 1,000 degrees hotter than previously thought

Scientists have determined the temperature near the Earth's centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature ...

Three ways to travel at (nearly) the speed of light

One hundred years ago today, on May 29, 1919, measurements of a solar eclipse offered verification for Einstein's theory of general relativity. Even before that, Einstein had developed the theory of special relativity, which ...

Magnon-based computation could signal computing paradigm shift

Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption. A magnon corresponds to the specific amount ...

A new candidate for dark matter and a way to detect it

Two theoretical physicists at the University of California, Davis have a new candidate for dark matter, and a possible way to detect it. They presented their work June 6 at the Planck 2019 conference in Granada, Spain and ...

Superconducting secrets solved after 30 years

(Phys.org) —A breakthrough has been made in identifying the origin of superconductivity in high-temperature superconductors, which has puzzled researchers for the past three decades.

Maglev track could launch spacecraft into orbit

(PhysOrg.com) -- With the aim to make it easier to launch spacecraft into low Earth orbit (LEO), two researchers have turned to maglev technology to catapult a payload hundreds of miles above the Earth. While the concept ...
