(Phys.org) —Physicists Joseph Silk of Institut d'Astrophysique de Paris and Jens Chluba of Johns Hopkins University have together published a Perspective piece in the journal Science, where they discuss the future of cosmological ...
A pair of researchers at the Czech Academy of Sciences has been shaking up the astrophysics community with a new modified Newtonian dynamics (MOND) theory that tosses out the concept of dark matter and instead backs up theories ...
Quantum technologies, a wide range of devices that operate by leveraging the principles of quantum mechanics, could significantly outperform classical devices on some tasks. Physicists and engineers worldwide have thus been ...
Einstein was right – changes in gravity do spread as waves through space. The LIGO experiment detected such waves from a collision between two black holes with masses of about 36 and 29 times that of the sun (described ...
