Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Physicists use dysprosium to put bounds on maximum speed of electrons
Albert Einstein's assertion that there's an ultimate speed limit – the speed of light – has withstood countless tests over the past 100 years, but that didn't stop University of California, Berkeley, postdoc Michael Hohensee ...
White dwarf star throws light on possible variability of a constant of Nature
An international team led by the University of New South Wales has studied a distant star where gravity is more than 30,000 times greater than on Earth to test its controversial theory that one of the constants ...
New method of finding planets scores its first discovery
(Phys.org) —Detecting alien worlds presents a significant challenge since they are small, faint, and close to their stars. The two most prolific techniques for finding exoplanets are radial velocity (looking ...
