Stacy McGaugh studies galaxies, cosmology, and the mass discrepancy problem. His primary interest is in low surface brightness galaxies. These diffuse objects tell us a great deal about galaxy formation and evolution.
If another gravity theory is correct, "then the broader implications are enormous," astrophysicist Stacy McGaugh told Newsweek.
"It is the only theory that has routinely had all predictions come true."
"The bottom line is: 'I told you so'," said McGaugh. He added: "I was raised to think that saying that was rude, but that's the whole point of the scientific method: make predictions and then check which come true."
