Will anything ever go the speed of light? they are testing with muons but have never succeded... mass ads on w/the amount of energy that you are adding to push it that fast any way so will it ever be possible?

I have a question about photons. They compose light, right? They are particles with zero mass, no electric charge, and an indefinitely long lifetime, right?
The thing that seems weird to me is - if they have zero mass, what keeps them from going faster, in fact - how can they even physically exist with 0 mass? It would seem to me that something with 0 mass could be capable of instant speed. Obviously, this is wrong. But why? What keeps light/photons "existing" the way they do?
Also, doesn't having a set "smallest amount of a physical quantity that can exist independently" seem illogical? (to me, it seems like logic should say you can break something down [that exists] indefinitely.) Obviously I am wrong, but how?

Take a tube full of marbles, place a device at one end to measure the impact and how long it takes from the time you push a marble at one end, until the impact is felt at the other end. Have a gap between all the marbles, that is virtually non existent, then measure how much of a delay between when you push the first marble to when the impact is felt at the other end of the tube. If you didnt know that the tube was full of marbles then it would look like the marble had traveled at 300,000 kps.
this is where science fowled up big time, because rather than look at what had happened and said to themselves, "if light did travel that fast, then surely it would cause enormous impact, let's inspect the experiment to see if it could be wrong" instead didnt bother, and took it for granted that the experiment was all the thought it was, and as a result made up laws to comply with what they had observed. Didnt stop to think that maybe in between the source and the destination, there is matter (dark matter) and so rather than light propogating from a to b that there is something in between, that allows an instant connection. Therefore if you were to be traveling with a light towards, the destination, then it would cause what is between to collapse making it appear as if light always traveled at the same speed.
Like I said, just primitive science, yet to fill in all the gaps.
No, according to Einstein's theory of relativity, it is impossible for any object with mass to reach the speed of light. As an object approaches the speed of light, its mass increases and requires more and more energy to accelerate, making it impossible to reach the speed of light.
The speed of light in a vacuum is approximately 299,792,458 meters per second, or about 670,616,629 miles per hour. This is the fastest speed at which energy, information, or matter can travel in the universe.
The speed of light is considered the cosmic speed limit because it is the maximum speed at which anything can travel in the universe. This is due to the fundamental laws of physics, including Einstein's theory of relativity.
No, as mentioned earlier, the speed of light is the maximum speed at which anything can travel in the universe. While there have been claims of particles traveling faster than the speed of light, these have been disproven and are most likely due to measurement errors.
Einstein's theory of relativity states that as an object's speed approaches the speed of light, time slows down for that object and its length contracts in the direction of motion. This phenomenon is known as time dilation and length contraction and has been proven through various experiments and observations.
