Ytterbium atomic clock could open a new window on fundamental physics

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to fundamental physical effects. Publishing their results in Nature Photonics, the researchers, led by Taiki Ishiyama at Kyoto University, say their approach could pave the way for some of the most stringent tests yet of predictions made by the Standard Model. Underperforming precision To measure the passing of time, an atomic clock excites an electron in confined atoms to a higher energy level, then interrogates the transition frequency of the atoms. Because these oscillations display such little variation, atomic clocks are the most accurate timekeepers ever developed.

Quantum Footprints in the Cosmos: The Calculus of Space Exploration Quantum mechanics governs the behaviour of particles at microscopic scales. But space, with its vacuum, high radiation, and zero-gravity conditions, reveals phenomena that only quantum physics can explain. From precision in navigation systems to understanding black holes, quantum mechanics enables us to interpret and engineer…

Doing this on here bc i have no one to talk to abt science.

Time is based on the atomic clock.

It uses the two lowest states of a cesium-133 atom.

The cesium atom get bombarded with microwave radiation at a specific(9.19263177 GHz) frequency.

From the microwave radiation the cesium atoms undergo a transition from one state to another.

One second is defined as the time required for 9,192,631,770 cycles of the microwave radiation.

It also reverses the outermost electrons spin.

Here is a Spiritual Conundrum submitted to Spiritual Insights for Everyday Life by a reader named Carl McGuire: What’s the difference between time in heaven and time on earth? Here on earth, the events of our lives unfold against a background of regular cyclical events. For as long as humans have lived on this planet, our lives have been arranged by: years, determined by the earth’s orbit around…

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter. In a collaboration between the University of Queensland, Australia, and Germany's metrology institute (Physikalisch-Technische Bundesanstalt, PTB), the team used data from atomic clocks and cavity-stabilized lasers located far apart in space and time to search for forms of dark matter that would have been invisible in previous searches. This technique will allow the researchers to detect signals from dark matter models that interact universally with all atoms, an achievement that has eluded traditional experiments.
