SUMMARY
The discussion centers on the apparent lack of skew in galaxies despite the vast distances light travels over time. It is established that the average dynamical time of a galaxy is approximately 200 million years, which is significantly longer than the light crossing time of 100,000 years. This discrepancy in time scales explains why galaxies do not appear skewed when observed from Earth, as their structural changes occur over much longer periods than the time it takes for light to travel across them.
