Fundamental constants: A cool way to measure big G

  title={Fundamental constants: A cool way to measure big G},
  author={Stephan Schlamminger},
Published results of the gravitational constant, a measure of the strength of gravity, have failed to converge. An approach that uses cold atoms provides a new data point in the quest to determine this fundamental constant. See Letter p.518 The Newtonian gravitational constant G, also known as the universal gravitational constant or 'big G', is a fundamental physical constant that is used in the calculation of gravitational attraction between two bodies. There are several ways to measure G…

Measurements of the gravitational constant using two independent methods
Two independent determinations of G are reported using torsion pendulum experiments with the time-of-swing method and the angular-acceleration-feedback method, yielding results with relative standard uncertainties of 11.6 parts per million—the lowest uncertainty reported until now.
Precision measurement of the Newtonian gravitational constant
The history of the G measurement is briefly reviewed, and eleven values of G adopted in CODATA 2014 after 2000 are introduced and the latest two values published in 2018 are introduced using two independent methods.
Progress in Precise Measurements of the Gravitational Constant
The Newtonian gravitational constant G, which is one of the earliest fundamental constants introduced by human beings, plays an important role in cosmology, astrophysics, geophysics, metrology, and
The Mass Gap, Kg, the Planck Constant and the Gravity Gap
In this paper we discuss and calculate the mass gap. Based on the mass gap we are redefining what a kilogram may truly represent. This enables us to redefine the Planck constant in what we consider

The Newtonian gravitational constant is regarded as the most fundamental constant. So far, more than 200 experiments have been done to measure its true value. But large discrepancies in those results
Planck Quantization of Newton and Einstein Gravitation
In this paper we rewrite the gravitational constant based on its relationship with the Planck length and based on this, we rewrite the Planck mass in a slightly different form (that gives exactly the
A dual-magneto-optical-trap atom gravity gradiometer for determining the Newtonian gravitational constant.

In this paper we suggest a new way to write the gravitational constant that makes all of the Planck constants; Planck length, Planck time, Planck mass, and Planck energy much more intuitive and
Newton’s and Einstein’s Gravity in a New Perspective for Planck Masses and Smaller Sized Objects
Here we derive Newton’s and Einstein’s gravitational results for any mass less than or equal to a Planck mass. All of the new formulas presented in this paper give the same numerical output as the


Precision measurement of the Newtonian gravitational constant using cold atoms
The precise determination of G is reported using laser-cooled atoms and quantum interferometry to identify the systematic errors that have proved elusive in previous experiments, thus improving the confidence in the value of G.
Determination of the newtonian gravitational constant using atom interferometry.
Freely falling samples of laser-cooled rubidium atoms are used in a gravity gradiometer to probe the field generated by nearby source masses to measure the Newtonian gravitational constant G based on cold-atom interferometry.
Don't stop the quest to measure Big G
The search for a theory of quantum gravity that is consistent with quantum electrodynamics is perhaps the most active field of theoretical physics, and the measurement of Big G, the coupling constant in Newton’s law of gravity, is a good place to start.
Improved determination of G using two methods.
The apparatus has been completely rebuilt and extensive tests carried out on the key parameters needed to produce a new value for G, which confirms the discrepancy of the results with the CODATA value and highlights the wide divergence that now exists in recent values of G.

Measurement of Newton's constant using a torsion balance with angular acceleration feedback.
Newton's gravitational constant G is measured using a new torsion balance method that is insensitive to anelastic torsions fiber properties, and a flat plate pendulum minimizes the sensitivity due to the pendulum density distribution.
Two preliminary determinations of the Newtonian constant of gravitation have been performed at Los Alamos National Laboratory employing low-Q torsion pendulums and using the time-of-swing method.
