... There was no such thing as ''Time'' before the Universe existed. Well, there was no such thing as *anything* before the Universe existed. No space, no time, nothing. The Universe will come to an end and after that,there will still be no such thing as ''Time''. When the Universe ends there will be no such thing as *anything*. ''Time'' has no meaning whatsoever in the big grand scheme of whatever. Very little has meaning in the big grand scheme of whatever. Mike |

Without it, you could NOT make the universe--you simply would not have the time! Well, you would have no space for it, either! Without space, you could NOT make the Universe--you simply would not have the space! If time existed before the Big Bang, then space existed also. You can't have one without the other. Our SpaceTime started at the Big Bang. What existed before is pretty much irrelevant, sort of like How Many Angels Can Dance On The Head Of A Pin. Mike |

Mike You, yourself, claim there is NO ether, that space is truly nothing ... Yet, now you say there would be no space for such in NOTHING? scratch head here The ether appears to permeate everything and every form of matter. It appears there is so much "room" between our atomic and sub-atomic particles that ether flows through it as wind does a screen. Matter fit quite nicely, simply displacing a portion of the ether (perhaps a minor compression?) But, this is only a "theory", much like the "generally accepted theory." While in high school physics we learn "truths", in the real physics world we realize we lack many answers ... A few universities still research, construct and do experiments in regards to the ether ... some admit we still cannot prove that the ether is non-existent, and if found to exist, realize we will once again rewrite what we know, a task already done many times.

... Mike Let's cut the BS and sharpen Occam's Razor a bit. A train whistle will increase in pitch (frequency) as the train comes towards you, and decrease in pitch as the train travels away from you. If you mount a laser on a space vehicle capable of thousands of miles per hour, the same doppler effect can be see. The light will switch frequencies when viewed approaching as when seen receding. Liken the train whistle to air, as the laser to ether. Sound cannot propagate in atmosphere faster than a set limit. Light cannot traverse the ether for the same reason. The change in tone is due to "compression" of the audio frequencies due to the increase/decrease in train motion as opposed to the limit of sounds speed in the atmosphere. Same for the laser, the light frequencies are "compressed" due to motion. Now, I am sure much more complex explanations can be constructed ... JS |

Mike You, yourself, claim there is NO ether, that space is truly nothing ... I never said that "space is truly nothing". There are lots of things in space, things that we can detect. I just don't believe in things that we can't detect - like "ether". If "ether" is ever detected and proven, then I will acccept it. To accept something which can not be detected sounds like religion to me. Yet, now you say there would be no space for such in NOTHING? scratch head here If you truly had nothing, then there would be no space. But if you have space, you have something. And if you have space, you also have time. Mike |

The sound waves will also be coming at you faster as the train comes toward you, and slower as the train travels away from you. If you mount a laser on a space vehicle capable of thousands of miles per hour, the same doppler effect can be see. The light will switch frequencies when viewed approaching as when seen receding. Light however, is unaffected by the motion of the transmitter or the receiver. It is always exactly c. Again, light is not a mechanical wave. It is particles with some wave-like properties. Mike |

No. The speed of sound, in the atmosphere, is fixed, it cannot be exceeded. What is happening is that the horn is emitting a frequency, just for example, say 2000HZ. But, the speed of the train is moving the horn forward at some speed, what this is causing is a "shortening" of the sound wave being emitted by the horn--while the tone is leaving the horn at the speed of sound, the next instant of that tone wave is being "jammed" at the beginning of the tone wave, and at the speed which the train is traveling--this is effectively "shortening" the length of the sound wave and raising the perceived frequency of the tone. Or, in other words, if the train is going the speed of sound, it will reach you at the same time the sound its horn is emitting will. This is why you see some aircraft pass over before you hear their sound (sonic shock wave) Now, throw a rock from the train and (rock speed + throw speed = total speed)--but, depending on train speed vs. wind friction--this speed will decline quickly. Indeed, at some speed, wind friction will make it impossible for you to throw the rock! JS |

There is a Railroad Track one and a half miles North of me.I can hear
very distinctly when those Trains are moving along.Sometimes,it's like those Trains are just down the block from me.Luverly sound waves. cuhulin |

You need to get a physics book. Start at the high school level and try to
work your way up. -- Brian Denley http://home.comcast.net/~b.denley/index.html "John Smith" wrote in message ...

In the past, germs were not accepted, the world was believed to be flat, radio was thought to be impossible, the laser (buck rogers ray gun) was thought a toy, etc., etc., etc. The fact that equations need to involve time (time does not really exist) or the "imaginary" number 377 ohms to describe the "impedance" of the ether proves there is a yet undiscovered "matter." For now, ether serves as well as any other term ... Get a clue. JS |
