Would the speed of light be effected by the mass of light. Is the speed of light relative to mass? In other words if you fuse photons will they be capable of reaching beyond C?
Photons of light have no mass and nothing can travel faster than the speed of light.Nuradh said:Would the speed of light be effected by the mass of light. Is the speed of light relative to mass? In other words if you fuse photons will they be capable of reaching beyond C?
To add to The Borg's response, you are probably under the misapprehension that velocities add linearly and can get something to move faster than c. This is not correct. Google "relativistic velocity addition".Nuradh said:Would the speed of light be effected by the mass of light. Is the speed of light relative to mass?

As has already been pointed out, but I will repeat it since you seem to have missed it, light (photons) HAS no mass, so mass has nothing to do with the speed of light. The speed of light has been determined fairly closely by experiment, but is now DEFINED to be exactly 299,792,458 meters per second.Nuradh said:Relativistic velocity addition already has a constant locking the speed of light into C, I'm attempting to ask what was the speed of light determined by? Was it mass, empirical experiments? Theoretically calculated ideas? Where does it show the speed of light as function of something? Did that something have to do with mass? If so how? And no! E=MC^{2} will not do for this
The speed of light was originally determined by the Danish astronomer, Ole Roemer while observing the orbits of Io around Jupiter. He noticed that the apparent motion Io changed as the Earth moved from one side of the sun to the other in relation to Io. From this, he was able to calculate the first estimates of the speed of light.Nuradh said:Relativistic velocity addition already has a constant locking the speed of light into C, I'm attempting to ask what was the speed of light determined by?

The consistancy of the speed of light is one of the two postulates of Special Relativity:Nuradh said:Where does it show the speed of light as function of something?
These two starting assumptions came about from Einstein trying to resolve two issues in physics:(1) that the laws of physics are invariant (i.e., identical) in all inertial systems (non-accelerating frames of reference)
(2) that the speed of light in a vacuum is the same for all observers, regardless of the motion of the light source.
In order to completely understand how light and mass mathematically relate to each other, you have to have take college level courses in calculus and electromagnetism in order to have the basics needed to do the math. Proving the relationship comes from the math.The inconsistency of Newtonian mechanics with Maxwell’s equations of electromagnetism and the inability to discover Earth's motion through a luminiferous aether led to the development of special relativity, which corrects mechanics to handle situations involving motions nearing the speed of light.
You are asking this 'the wrong way round', I think. c is a fundamental constant (at least, all our measurements seem to confirm this). It is tightly bound to the relationship between electric and magnetic fields, so, rather than being "determined by", it is "part of a structure which our present model is based on".Nuradh said:Relativistic velocity addition already has a constant locking the speed of light into C, I'm attempting to ask what was the speed of light determined by?

There is no experimental evidence at all that light has mass so it seems pretty clear to me that the question has no relevance to the real world.Nuradh said:-"does the speed of light change if the mass of the light change?
In a single sentence, and with a single usage, you are using "the speed of light" to mean two entirely different things. First, there is a "universal speed limit" which is the speed limit of all massless things. We know that light is massless and for historical reasons, we use the term "speed of light" to mean "the universal speed limit" although the universal speed limit is in fact independent of the actual speed of light. Second, if light DID turn out to have mass, no matter how tiny (which it does not) then it would NOT travel at the universal speed limit so in that sense it would not travel at "the speed of light" as used in the first item, it would travel at what I suppose we would come to call "the speed of photons" just as we talk about "the speed of neutrinos".Nuradh said:-"Would the speed of light be effected by the mass of light"
If you "fuse" two photons then you get an electron and a positron. They travel with v<c.Nuradh said:In other words, if you fuse two photons, will they be capable of traveling faster than the speed of light of one photon? c?
Nuradh said:"Would the speed of light be effected by the mass of light"
The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).
The speed of light is related to mass through Einstein's famous equation, E=mc², which states that mass and energy are equivalent and that the energy of an object is equal to its mass multiplied by the speed of light squared.
No, the speed of light is a constant and is the same for all objects regardless of their mass or velocity.
According to Einstein's theory of relativity, it is not possible for anything to travel faster than the speed of light. This is because as an object approaches the speed of light, its mass increases and it requires an infinite amount of energy to accelerate to the speed of light.
The speed of light is the fastest speed at which all matter and information can travel. It is also a fundamental constant that plays a crucial role in Einstein's theory of relativity, which states that time and space are relative and can be affected by an object's speed and mass.
