Astronomers, astrophysicists and particle physicists gathered recently at the Kavli Institute for Theoretical Physics at the University of California to discuss the seriousness of differing measurements of the Hubble Constant. ...
(Phys.org)—A team of researchers at Vrije Universiteit Amsterdam has built, for the first time, a molecular fountain. The group has published a paper in the journal Physical Review Letters describing how they created the ...
Fundamental constants are physical quantities that are universal in nature. For example, the speed of light in vacuum and the charge of a single electron are the same everywhere in the universe. That is why scientists would ...

(Phys.org)—Scientists have proposed an experiment that could measure the value of Newton's gravitational constant, G, from deep space instead of an Earth-based laboratory. The researchers predict that the deep space experiment ...
The fundamental constants that govern the laws of nature are being determined with increasing accuracy, according to a review paper published this week in Journal of Physical and Chemical Reference Data.
