JILA Atomic clock


In 2022, researchers at JILA conducted a groundbreaking experiment using atomic clocks to probe the effects of gravitational redshift and explore the hypothesis of space’s admittance variation with height, as proposed by Quantum Admittance. By vertically stacking strontium atoms and measuring the gravitational redshift-induced frequency differences, the experiment provided insights into the nature of quantum gravity and the relationship between oscillation frequency speed and changes in mass.


Atomic clocks, renowned for their precision, offer a unique opportunity to investigate subtle gravitational effects and test theories of quantum gravity. The 2022 experiment conducted at JILA aimed to detect and quantify gravitational redshift by vertically arranging strontium atoms and measuring the frequency shifts induced by Earth’s gravitational field. This experiment also sought to explore the QA hypothesis, which suggests that space’s admittance varies with height.

Experiment Details

Researchers at JILA meticulously prepared a stack of strontium atoms, forming pancake-shaped blobs and arranging them vertically with optical light trapping. By shining a laser onto the stack and observing the scattered light with a high-speed camera, the team measured the gravitational redshift-induced frequency differences between the top and bottom of the stack. This precise measurement allowed for the detection of gravitational effects on the oscillation periods of energy.

Results and Significance

The experiment revealed a gravitational redshift effect, with the frequency of oscillations in each group of atoms shifting by different amounts due to Earth’s gravity. This finding supports the QA Theory hypothesis, suggesting that space’s admittance varies with height. The observed frequency differences confirm the intricate relationship between oscillation frequency speed and changes in mass, shedding light on the underlying mechanisms of quantum gravity.


The JILA represents a significant advancement in our understanding of gravitational effects and their implications for quantum gravity. By detecting gravitational redshift-induced frequency differences in vertically arranged strontium atoms, the experiment provided empirical support for the Z0 Theory hypothesis and offered insights into the relationship between oscillation frequency speed and changes in mass. These findings contribute to ongoing research efforts aimed at unraveling the mysteries of gravity and advancing our understanding of the fundamental nature of the universe.
