How does one calculate the distance from a galaxy or galaxy cluster where recession due to dark energy begins and "attraction" ends?
A good technical discussion can be found in: On the influence of the global cosmological expansion on the local dynamics in the Solar System, Carrera et al. They do extend it to larger scales as well.richardSPM said:If you have an object, galaxy or galaxy cluster, of known mass how does one calculate the distance from said galaxy where it no longer has an effect on the curvature of space-time? (ie there is no longer an attractive force) I assume it would be at this distance that expansion would begin to cause recession.
Hi Richard, if I remembered correctly, SPM is a personal theory of yours that we did discuss on another forum. If I'm correct, then discussion of SPM is not allowed on this forum, which is reserved for mainstream theory and papers published in scientifically reputable media. I trust that you have read the general forum guidelines?richardSPM said:According to the SPM, recession would begin at a distance equal to the radius of a sphere that had a density equal to the critical density with the object at its center. Is this not a currently accepted premise based on LCDM?

To calculate recession and attraction, you need to use the gravitational force equation: F = G(m1m2)/r^2, where F is the force of attraction, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them. The force will be positive if the objects are attracting each other and negative if they are receding from each other.
Recession and attraction are opposite forces that act between two objects due to their masses. Recession is the tendency of two objects to move away from each other, while attraction is the tendency of two objects to move towards each other.
The distance between two objects has a direct impact on their recession and attraction. As the distance between two objects increases, their attraction decreases and their recession increases. This is because the force of gravity decreases as the distance between objects increases.
Yes, recession and attraction can be negative forces. This happens when the masses of the objects have opposite signs. In this case, the force of attraction will be negative, indicating that the objects are receding from each other.
The sign of the force can tell us whether two objects are experiencing recession or attraction. A positive force indicates that the objects are attracting each other, while a negative force indicates that the objects are receding from each other.
