If the physical universe, which includes light, had a beginning, would not light have had to accelerate to get to its current speed? Or did it just get to its current speed magically?
No, it doesn't "need" to accelerate, and no, it's not magical. Light, when emitted, propagates at the speed of light instantly, without any "acceleration." That is part and parcel of quantum physics.
