wrote: ... 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. 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. |

And since the frame of reference is a defined thing and not a physical reality, it doesn't matter if the Earth continues to exist or not either. You seem to have a lot of difficulty with this concept. A frame of reference based on 1/86400 of one rotation of the Earth which is only 1/3 as old as the universe? A frame of reference based on the oscillation frequency of Cesium when Cesium didn't even exist before the first super nova? I'm not having difficult with the concept. I'm just wondering why anyone would accept such a flawed concept. The 17th Century Catholic Church's frame of reference was earth-centric. So is our time frame of reference. Both are equally valid. -- 73, Cecil, http://www.qsl.net/w5dxp |

To be accererating, there would have to be a force . No, just a flawed frame of reference. If the length of a second is changing, something outside that frame of reference can appear to be accelerating when it really isn't. -- 73, Cecil, http://www.qsl.net/w5dxp |

Actually, the second is defined as a certain exact number of oscillations of a cesium atom in the same reference frame as the observer. The same problem still exists. The cesium atom didn't exist before the first super nova. How can the time be calculated between the Big Bang and the first super nova if cesium didn't exist? -- 73, Cecil, http://www.qsl.net/w5dxp |
