Musically Inspired Time-Rondeau Crystal Breakthrough Promises Quantum Technology That Stores Data Within Time Itself
Researchers at UC Berkeley report the first observation of a time-rondeau crystal, an unusual phase of matter in…
For the first time, astronomers observed the first moments of a supernova shock wave
Many cosmic events occur in space and sometimes surprise astronomers. This is the case of these scientists who…
Heavy atomic nuclei are not as symmetric as previously thought, physicists find
Until now, physicists thought that all heavy nuclei deformed from spheres are elongated in one direction like rugby…
Within Just 1 Second After The Big Bang, Black Holes May Have Come Into Being
Physicists agree that an awful lot went on in the first few seconds after the Big Bang, a…
