Time has Lost A Second, Again

This week an extra second was added to UTC and reported here.

This means the Earth has slowed down in its diurnal axial rotation, and the last time this leap second had to be added was 2012.

This rotational slowing down is also linked to solar activity, the connection being the sun-earth electromagnetic connection which is the likely driving electric current of the solar homopolar motor, is also decreasing. Or is it the voltage potential? The fact we have to add an extra day every four years, also means a slowing down. So this reduction in solar activity is being quantified in the Earth’s rotation. Reducing the driving current reduces the amount of energy coming into the system, and hence the temperature has to drop.

As the definition of the second was initially a fraction of the distance covered by the diurnal rotation, but now defined in terms of atomic frequency, and the earth is obviously slowing down, then the definition of time, the second, is not a constant.

This makes for all sorts of interesting problems in the reconstruction of the past.

It also makes for interesting forecasts of the future, but then prophesy is always the role of religion, not science.

About Louis Hissink

Retired diamond exploration geologist. I spent my professional life looking for mineral deposits, found some, and also located a number of kimberlites in NSW and Western Australia. Exploration geology is the closest one can get to practicing the scientific method, mineral exploration always being concerned with finding anomalous geophysical or geochemical data, framing a model and explanation for the anomaly and then testing it with drilling or excavation. All scientific theories are ultimately false since they invariably involved explaining something with incomplete extant knowledge. Since no one is omniscient or knows everything, so too scientific theories which are solely limited to existing knowledge. Because the future always yields new data, scientific theories must change to be compatible with the new data. Thus a true scientist is never in love with any particular theory, always knowing that when the facts change, so too must he/she change their minds.
