"It is certainly possible to modify gravity to get rid of dark matter and dark energy, but when you move that conversation about how that might happen from coffee table chit-chat at conferences -- "Well, maybe gravity is modified ..." -- to writing down a theory, to writing down an action that has consequences, you realize that the experimental constraints we already have are extremely constraining, and it's hard to do everything at once."
