It's been years since I've had a physics class but isn't one part of the theory of relativity or some shit like that concerning the speed of light comparative to a mass' velocity change the effect or passing of time(specifically on the mass at such velocity)? Such that as V approaches c, rate of time passing approaches zero.
So wouldn't that also complicate figuring out c if the source of light comes from somethign faster than c

You're right about the rate of time changing. The faster an object travels, the slower time appears to be according to the object, stopping completely at the speed of light. Therefore according to the driver of this theoretical FTL car, time would be going backwards. However this would not affect the speed of the light since it is a fundamental constant. The velocity of the emitter is completely irrelevant as light will *always* be traveling at the same speed. The only thing that can affect the speed of light is the medium through which it travels, for example; 3x10^8 m/s in a vacuum and 2x10^8 m/s in glass. second number's off the top of my head and may be wrong, but the point still stands.

I knew the speed of light was variable based on it's medium(the speed of light in the center of the sun is super fuckin slow, i recall reading like 3 m/s but that memory is likely distorted by time) however I did not know it was independent of it's source. If light's velocity is independent of it's source but dependent on medium wouldn't that support light being a wave? Of course light is a wave or a particle based on the experiment(as i recall) so it's not like that changes anything. Though I do recall neglecting why which experiments reliably produced different results

Wave-particle duality is due to the fact that all particles exist as a probability wave, represented as a wave function. The higher the probability of finding the particle in a certain place, the greater the frequency of the wave in the place. For example; for all "waves" of light their speed is equal to the wavelength times the frequency. Since the speed is constant, if the frequency were to go up, the wavelength would reduce, making the area the photon could be in smaller and the probability of finding it there higher. High frequency = high probability. If the particle is detected, eg. your eye detecting a photon, then the probability of finding it there is 100%. This is known as collapsing the wave function and the particle begins to act like a particle instead of a wave.
An experiment can produce different results depending on when the wave function is collapsed. If it happens before any wave-like properties can be observed then it will act as particle. Otherwise it will act as a wave.

Oh. Thats pretty neat. However it doesn't sound like we can actually do anything with that. Meaning is there any practical application that can become of that or is it just a nice little piece of information helping us understand things? also the way that is makes it sound like light is directly affected by other light

In fact, semiconductors and transistors rely heavily on this phenomenon in order to operate. I couldn't tell you exactly how it works, but they use the wave-like properties that electrons can exhibit to work. If the wave-particle duality was never discovered, then this huge technological revolution we've been observing for the last couple of decades would never have happened. Smartphones wouldn't exist, computers would be huge towers and still be slow as shit, consoles and gaming and other sorts of animation wouldn't have advanced anywhere near as much. The technology that so much of the world relies on would not exist without quantum physics.
Also, yes light can affect other light in the same way sound and water waves can. This is what interference in radios is.

so you're a cunt, and a thief, how does it feel being such a huge failure?
