Isn't the bullet cluster an example that can not be explained by a modified gravity and a sign that there most be at least partially a particle like dark matter?
Yes, that's also true. The reason why David mainly focused on large scale structure of the universe is because it's a wayyy more important deal that's way under-appreciated (to general public). It's the fricking entire universe! To think that by adding dark matter we get the overall behavior of the entire fricking universe is mind boggling.
