Eg a particle is emitted by a supernova and starts accelerating toward our galaxy, what limits its speed to keep it less than c?
Reasoning: its initial velocity was large, the acceleration due to mass of our galaxy is big allowing for initially it is smaller due to distance.
Initial high velocity + increasing acceleration due to mass of galaxy in the absence of drag = big + increasingly big - 0 drag = big much.
