Is it true to say that Einstein's special theory of relativity is based of the postulate thaat the sped of light is constant?

For the question as asked the answers is Yes. Theories are someones' idea, expressed in a method of communication within guidelines of societies. Presently there is a new THEORY of everything. I think you should give some time to review it. The speed of light is constant but it is in question, the speed. The ten dimensions are 1. Length, 2. Width, 3. Height, 4.Weight, 5. Area, 6. Volume, 7.Mass, 8. Velocity, 9. Time, & 10. infinity. Speed is not a measured unit which many will argue; but, rather a result of Velocity. Thus the speed of light is Relative to something other than Light. The visable spectrum measures nothing. Light is beyond the present accepted concept. No one on this Earth can conceive the vastness of the Universe. Too (to) many, the understanding that there is no end can not be. Get over it. There are no boundries. The only Cosmoligcal Constant is God. Furthermore it is not of any religion. Man created Religion but God was long before man. The Speed of Light is Relative.

If you turn on a laser pointer while moving close to the speed of light and mearsure that speed you will get C. No matter how fast you move so long as it is less than C you will always get C (the speed of light - aprox 300Km per second) Now an obersver at rest will also see your laser pointer and measure the speed at C too! But the laser pointer's color will not be the same. If the space traveler with the laser pointer is coming towards you it will be shifted to a shorter wave length (like red to blue) if the space traveler is moving away from you the frequency will be longer ( a red shift). The only value that can be changed to accomadate this shift is TIME. The space traveler is in a different time reference than an observer who is stationary. The space traveler's clock will appear to the observer to be moving more slowly than his own clock. Hope this helps, Cheers

Yes, that is the second postulate. More precise: the speed of light in a vacuum is constant and independent on the motion of the light source. The first is that the laws of physics are the same in all inertial frames of reference.

perhaps a better way to say this is: the speed of light is the same value for any observer in any frame of reference.
