> The whole reason we have a constant supply of theories attempting to explain observations currently attributed to dark matter in terms other than "dark matter" is that people feel the dark matter theory is stupid. No, that's not true. The reason we have a "constant supply" of dark matter theories is that all of the extant theories have been falsified by observations, including MOND. If this were not the case, dark matter would be a solved problem and would no longer be in the news. > The fact that a theory is false does not mean there is no evidence for that theory. What makes you think the IPU theory is false? The whole point of the IPU hypothesis is that it is unfalsifiable.
