@strange thanks for the response. I learned, and please correct me if I'm wrong, that most variations of the electromagnetic force (whether it be in the form of sunlight or radiation) are emitted due to the actions of the Weak force, so wouldn't that still indicate a force that propelled the photon (even if that photon has been traveling since the beginning of the universe, it would have been propelled by the big bang, a force).
Also on the question of black holes, it is said that the gravitational pull is the cause for the curving of space-time, and gravity is still a force.
@sensei, that's not entirely true. A theory is just that, a theory, and most theories are not proven (by experiment or calculation, for several years). Perhaps the reason why a ToE hasn't been developed is because scientists are working from the bottom up, rather than from the bigger picture downward. Atoms were theorized to exist long before we came up with calculations for them. The higgs-boson was theorized to exist years before we developed equipment sensitive or powerful enough to detect it. Just because we cant put our finger on it doesn't mean it doesn't exist. Just because we don't have calculations for black holes doesn't mean they don't make sense. As long as a ToE can explain the existence of everything from a singular perspective or theme, isn't it worth investigating?
