(PhysOrg.com) -- Based on studies of old volcanic basalt, scientists know that the Earth’s magnetic field reverses at irregular intervals, ranging from tens of thousands to millions of years. Volcanic basalt rock contains ...
Why does the observable universe contain virtually no antimatter? Particles of antimatter have the same mass but opposite electrical charge of their matter counterparts. Very small amounts of antimatter can be created in ...

(PhysOrg.com) -- The Earth's magnetic poles flip around every 200,000 years or so, with north becoming south and vice versa. Normally, the process takes 4-5,000 years and it ought to be impossible for the flip to be much ...
Imagine the world waking up one morning to discover that all compasses pointed south instead of north.

Chiral superconductors are unconventional superconducting materials with distinctive topological properties, in which time-reversal symmetry is broken. Two of the first materials to be identified as chiral superconductors ...
Using a network of vibrating nano-strings controlled with light, researchers from AMOLF have made sound waves move in a specific irreversible direction and attenuated or amplified the waves in a controlled manner for the ...

A large team of researchers from China, Taiwan and Australia has found evidence of faster-than-expected shifts in Earth's magnetic polarity several thousand years ago. In their paper published in Proceedings of the National ...
(Phys.org)—A team of researchers from the U.S., China, and Japan has developed a computer simulation of the sun that is able to show both large and small scale processes. In their paper published in the journal Science, ...
(Phys.org) —The sun's magnetic field is poised to reverse its polarity. The effects of the event, which occurs every 11 years, will ripple throughout the solar system and be closely monitored by Stanford solar physicists.
