Answer 1

there’s no real “force” involved. forces accelerate and decelerate things. massless particles just kind of… travel at the speed of light.

mass comes from interaction with something called the Higgs field, so you could sort of think of the Higgs field as being the thing that *prevents* things from going at *c*. things without mass don’t interact with this field, so they just… travel at *c*.

(note: light *can* travel slower depending on the material it’s travelling through, but you can’t grab it and slow it down like you could with, say, a cannonball)
