(Phys.org)—Researchers from Stanford University and Princeton suggest in a paper they've had published in the journal Science that magnetic fields associated with some black holes may be strong enough to cause thick accretion ...
Since the mid-1800s, scientists have been systematically measuring changes in the Earth's magnetic field and the occurrence of geomagnetic activity. Such long- term investigation has uncovered a number of cyclical changes, ...
