How & What causes Light to Go at exactly the Speed of Light ?? Why not Faster or Slower ??

Question

I'm wondering what property of matter, energy, time, and/or space causes the measured speed of light ("c") to be fixed at precisely the speed that it is? Which is 300,000 Kilometers/ Second.

What causes Light to go at this Precise speed ?????

Why can't it go Faster or Slower ??????

Like what's the fuel that propels light to go at the precise speed of 300,000K/Sec ??????

& For that matter, What propels Light to even move at all ??????

Like Cars. In order for Cars to move, they need an engine, which in turn the engine needs some sort of Fuel to function. Today that fuel is Gas, in the future it wil be Electricity or Hydrogen, or Fuel Cells or some sort of fuel.

Humans Need fuel too, such as Food & Water, in order for the human being to continue on Living & Moving.

My computer needs Electricity in order to function.

Conclusion: Nearly everything that moves or Functions Needs some sort of fuel in order to keep on going.

To Conclude: What's the fuel that propels light to go at a speed of 300,000K/Second ?? Why not Faster ?? or Slower??

Is the fuel some sort of property of matter, energy, time, and/or space ?? That propels Light at the Speed of 300,000k/ Second.

Or are these questions still Questions with No Answer.

Has science still not come up with answers for these Questions Yet ??

Answer 1

god has tuned the world this way!  

Answer 2

Questions like how and why cannot be answered when you get to fundamental quantities like the speed of light, mass of electron, charge of electron, Heisenberg uncertainty value, etc.

They just are.

PS, speed of light is 299,792,458 metres per second, not the number you quote.

Answer 3

If it went half as fast, then *that* would be called the speed of light, and you would be asking the same question. Quibbles about units and definitions aside, the speed of light, like the mass of the electron, and Planck's constant is, at present, a "phenomenological property". That means the most basic underlying theory includes it as an arbitrary constant, which must simply be measured and input. That theory (relativity) simple states that all massless particles (like photons) must always travel (in vacuum) at a universal fixed constant speed in all reference frames. That is, indeed, the fundamental premise of the theory that seperates if from Newtonian theory, so there is no further explanation.

Answer 4

Visible and invisible light travels as mass-less packets of energy.  The wave length depends upon the amount of energy carried by the photon.  For example, UV light is more energetic and penetrating than visible light or longer wavelength infrared light, and can penetrate thin clouds and cause a sunburn on an overcast day.  X-rays have even shorter wavelengths and are more penetrating (passing through flesh and bone).  Gamma rays have even shorter wavelengths and are so penetrating they can pass through limited thicknesses of steel or lead.  The only thing that can be changed for a photon is its energy level which changes its wavelength but not its speed.  That might be a little like adding more power to a car's engine that changes the car's length but not its governed speed.  All photons travel at the speed of light because their energy levels affect their wavelengths but not their speed.  That may also be similar to exactly containing a gallon of water within a cylinder by varying its length and diameter.  There is nothing else that can be physically changed.  

Answer 5

When your dealing with the behavior of light, it is hard to understand.. How & what causes light to go at exactly the Speed of Light and why not faster or slower?? Light can't travel faster than the speed of light because it will need an infinite energy which is impossible.. Light only travels at constant speed that's why it can't travel slower or faster..

PS-----  He quoted that right.. It is the same... He just quoted it in                                             km/second and yours is in m/second...  

Answer 6

You are making the mistake of thinking of light as some "stuff" that travels at a particular speed, in the same way that a solid object moves. The truth is much stranger than that.

What we call light is a transfer of energy between two particles (usually electrons). One electron loses some energy, and some time later another particle gains exactly the same amount of energy. The time delay between the two events is proportional to the distance between them. It looks as though a particle of light (a photon) has travelled from one electron to the other, but really we cannot say that "a photon travelled from A to B at the speed of light", because we can never see it travelling. In fact, photons do some really weird things when they are "in transit" from one electron to another, for instance, a photon from a distant star interacts with every part of a telescope mirror in order to end up at the right spot on the detector plate or on your retina.

There is a fixed set of rules that govern how everything behaves in the universe. When physicists talk about finding a theory that explains how energy and matter behave, what they really mean is finding out what the rules are. One of the rules says that light energy takes longer to be transferred the further it has to go, and the relationship between time and distance is what we call the speed of light.
