Not me, dude. Sorry, but I've never heard of it. The closest that I can think of is that it's a reference to relativistic time dilation.gran_johansen said:Hei
Does anyone know what this means?
"Comoving time rate og change" ?

Comoving time rate of change is a concept used in cosmology to measure the relative change in distance between two objects in the universe over time, taking into account the expansion of the universe.
Comoving time rate of change is calculated by dividing the comoving distance between two objects by the difference in their redshift values. This measurement helps account for the expansion of the universe and allows for more accurate calculations of distance and time in cosmological studies.
Comoving time rate of change is important in cosmological studies as it helps us understand the evolution of the universe and the movement of objects within it. It also allows us to accurately measure distances between objects, which is crucial in determining the age of the universe and the rate of expansion.
Comoving time rate of change takes into account the expansion of the universe, while proper time does not. Proper time is the time measured by a clock at a specific location, whereas comoving time is a universal time standard that accounts for the expansion of the universe.
No, comoving time rate of change cannot be observed or measured directly. It is a theoretical concept used in cosmology to make calculations and predictions. However, its effects can be observed in the redshift of distant galaxies, which is used to calculate comoving distances between objects in the universe.
