How does light manage to travel through void if there are no particles? How does the "perturbance" get transmited?

Light is the ballistic trajectory of photons in vacuum. What medium does a bullet need when it travels through vacuum? The only difference is that light falls according to Einstein not according to Newton.

because light is actually a very strange phenomenon. The reason being is because light is waves, but has also been proven to be particles. but these particles can travel through void, all types of waves and particles can travel, we have radio waves and ultra violet waves, that is why we can get transmitions from our satellites and get cancer from the sun. that is like asking why there is any type of particle moving through a void, such as how can there be planets in a void, because technically we are all in a void. The only thing that nothing, not even light can travel through, is a black hole, this takes in and, doesn't destroy, but disperses all atoms and waves into very seperate and singular particles, everything is split as small as it can be in a black hole, but anything can travel through a void, even air can, but this air gets dispersed throughout the infinite miles of the universe.
the reason why waves are not dispersed, such as light, is because these have different properties than particles, and travel in a straight line, but curving up and down the whole time
like a wave at the beach, all the waves go straight for the beach, but they move up and down
they just travel through because that is how they were made
