This analysis is part of a sequence of logical steps that are described in Investigation.
Bok Globules are small molecular clouds as shown on the right. They are typically a few light years in diameter and contain a few solar masses of gas and dust. They are almost opaque and have particularly clearly defined surfaces. According to the AGM Theory (and as explained in Behaviour) they are sufficiently dense to have excluded the antigravity matter from within. Their surface is defined by the transparent antigravity matter around them. Their surface is their AGM Boundary and the visible object is at the AGM Exclusion Density.
Data relating to several Bok Globules have been published in Source. This includes an estimate of the mass of the Bok globules measured by absorption of radiation from background stars. Data extracted from that publication are shown in the table below along with a calculation of the radius and average density of the Bok globules. Angular radius is taken from Table 4 of that publication. Other data are taken from the second lines of Table 5.
Graphs of Bok globule density against mass and Bok globule radius against average density is shown below. More massive Bok Globules are on average less dense. The correlation coefficient for log(Radius) against log(Density) is -0.951. The probability of such a correlation occuring by chance is less than 0.0001.
The solid red line is a prediction from the AGM Pressure Simulation of how the AGM Exclusion Density and the radius of the AGM Boundary vary as the mass of a normal matter object varies. This is referred to as the Dnx Line. It should be noted that varying the values of the simulation parameters Gna, Gaa, Dab and Pab causes the Dnx Line to move on the graph. This has been done to make the line pass through the Bok globule points. However varying those values will not change the gradient of the line. The gradient has a value of approximately -0.5 on this log/log graph. This is explained in Investigation.
The radius data points that derive the Dnx line are based on the R1 definition of the AGM Boundary as described in AGM Pressure Simulation.
