Cecil: I feel like a damn idiot, this guy has been at this for sometime (this is from 2004), bet Richard has been having a laugh, look at the following: Richard Harrison wrote: Richard Clark wrote: "This paradox (differing light intensities in various directions) was solved by?" I have not seen that question before, but will speculate that Edwin Hubble deserves the credit as he used "red shift" in the light from other galaxies to show that they are speeding away from us and our galaxy. In fact, they are accelerating so that the farther the galaxy is away from us, the faster it is moving away. From continuous acceleration, the distant galaxy will eventually reach the speed of light. Then, light from the distsnt galaxy won`t reach us because it will tag along with the fast moving galaxy. There may be a time shortage too as Einstein has shown time slows as a thing moves faster. Hubble has also shown that the Doppler effect would shift the frequency lower as velocity of the retreating thing increases. Shift the frequency low enough and the wave is no longer described as light but may be classified as a millimeter radio wave. Best regards, Richard Harrison, KB5WZI To be accererating, there would have to be a force . Where would this force be coming from and what pray tell is directing it? The speed of light is a constant in all reference frames. If a light source were to be moving at the speed of light away from an observer, an impossiblity in itself, the light would still be moving at c towards the observer. The part about force is badly worded, I admit. However, are you saying the speed of light is not constant in all reference frames? If so, you are a damn idiot. -- Jim Pennino Remove .spam.sux to reply. |

Even the speed of sound is fixed in our atmosphere (approx. 770 mph at sea level.) A moving object emitting sound can only "jam" the beginning of the sound wave towards its end, effectively "shortening" that sound wave and raising the pitch--the opposite can also occur. Pure babble. Sound is a mechanical effect and requires a progation medium. Light is an electromagnetic effect and does not require a medium. One has nothing to do with the other. We call this the doppler effect, it can also occur with light (has a fixed speed in the ether) and yes, even our rf transmissions. More babble. That is not the doppler effect and there is no ether. I found that old piece of text when checking up on exactly what type of "discussions" you engage in; what I was pointing out with it is--YOU ARE A TRUE TROLL! You are, NO JOKE, the real thing! And you are a true, babbling, ignoramus. Lest someone believe your ignorant babble: Speed of light and reference frames From http://en.wikipedia.org/wiki/Speed_of_light "One consequence of the laws of electromagnetism (such as Maxwell's equations) is that the speed c of electromagnetic radiation does not depend on the velocity of the object emitting the radiation; thus for instance the light emitted from a rapidly moving light source would travel at the same speed as the light coming from a stationary light source (although the colour, frequency, energy, and momentum of the light will be shifted, which is called the relativistic Doppler effect). If one combines this observation with the principle of relativity, one concludes that all observers will measure the speed of light in vacuum as being the same, regardless of the reference frame of the observer or the velocity of the object emitting the light." Doppler effect http://en.wikipedia.org/wiki/Doppler_effect "The Doppler effect, named after Christian Doppler, is the apparent change in frequency and wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted." Relativistic Doppler effect http://en.wikipedia.org/wiki/Relativ...Doppler_effect "The relativistic Doppler effect is the change in frequency (and wavelength) of light, caused by the relative motion of the source and the observer (like in the regular Doppler effect), when taking into account effects of the special theory of relativity. The relativistic Doppler effect is different from the true (non-relativistic) Doppler effect as the equations include the time dilation effect of special relativity. They describe the total difference in observed frequencies and possess the required Lorentz symmetry." Speed of sound http://en.wikipedia.org/wiki/Speed_of_sound "The speed of sound is a term used to describe the speed of sound waves passing through an elastic medium. The speed varies with the medium employed (for example, sound waves move faster through water than through air), as well as with the properties of the medium, especially temperature. The term is commonly used to refer specifically to the speed of sound in air. At sea level, at a temperature of 21 ?C (70 ?F) and under normal atmospheric conditions, the speed of sound is 344 m/s (770 mph)." What is sound http://en.wikipedia.org/wiki/Sound "Sound is a disturbance of mechanical energy that propagates through matter as a longitudinal wave." What is light http://en.wikipedia.org/wiki/Light "Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light) or, in a technical or scientific context, electromagnetic radiation of any wavelength." Anything else you would like explained, like where rain comes from? -- Jim Pennino Remove .spam.sux to reply. |

Not a concept that is easy to explain. |
