Dear Ollie B Bimmol: On Aug 30, 1:25 am, Ollie B wrote: Yousuf wrote: .... Don't think of the speed of light in terms of miles/second or km/sec. Another way to look at the speed of light is that it represents the time it takes energy to flow within the smallest unit of space in universe, within the smallest unit of time in the universe. The smallest unit of space is called a Planck Length, and the smallest unit of time is called a Planck Time. Here Youself is promoting yet another flavor of "magic numbers". Continuous approximations to this universe start breaking down at nanometer scales and larger. No need to go "smaller than quarks" for any sort of granularity. This is true, the Planck scale is so far below the quark scale that it really doesn't make sense talking about it with today's level of technology. And the quantum nature of particles makes everything as tenuous as a cloud anyway. There is no length smaller than a Planck Length, or a time shorter than a Planck Time. The speed of light is 1 Planck Length/Planck Time. When you look at it this way, you notice that the speed of light is equal to exactly 1! Not in the mks system of units, 1 planck length / 1 plank time = c exactly. Nothing can be simpler. Not playing with magic numbers in the first place, and not spreading your personal illness to a novice would be another. And there lies the difference between the "universe is a continuum" and the "universe is discrete" camps. Yousuf Khan |

Oh, now it is more clear to me, this feels more right. Seems to me physics is a big battle field, all these theories. I will listen to both sides, maybe when they split a quark something smaller will happen, how big is an electron? I could not find that. It really is, and believe it or not, David and I agree on a lot of things most of the time. The stuff I told you about Planck units is purely theoretical, we don't have the technology yet to test down at the Planck scales yet. However, knowing about Planck units does help you understand the background to why light speed may be what it is. Yousuf Khan |

They only ever interact via their field, no matter how "close" they come to something else or each other. Protons and neutrons suddenly change from one type of interaction to a different type, as collisions start involving "bumpers and flying glass". And of course, they are composite particles too... Current established theories of physics like the Standard Model of Quantum Mechanics treats these particles as point particles. However, according to various next-generation theories, such as Superstring theory, those point particles are actually strings that are 1 Planck Length in diameter. The next gen theories suggest that the Standard Model point particles are just an approximation, which will disappear the closer we get to the Planck scale. Yousuf Khan |

So the light emitted again from the mirror always leaves at c relative to that mirror. I mean even if it came in faster? It can't come in faster than c. If it did, then they'd be able to detect the speed difference in this MMX apparatus. Look at the animation of the MMX apparatus. When light is travelling with an "aether wind" at its back, it is speeding up. When it's travelling with the aether wind at its front, then it's slowing down. When the two beams recombine, there should be an interference pattern that represents the two speed differences in the split light. Since they never detected those differences, it means light was travelling at exactly the same speed coming and going. Yousuf Khan |

Yousuf Khan Why 4 dimensional, should that not be 3 dimensional? Would anything sort of float in that fluid? The 4th dimension is time. Thus the modern concept of an aether would be a space-time aether, rather than a space-only aether. Einstein's two theories of relativity pretty much erased the line between space and time as two different concepts. People have difficulty getting their heads around the concept of space and time being exactly the same thing, because they are so different in our everyday experience. Our everyday conception of space is that it is something that we have full freedom to move around in. We can move forward and then we can move back, we can move left and then right, and we can move up and down. Our everyday conception of time is that it is something that moves us around, we can only move forward in it, but never back. We have no freedom of movement in time, thus we don't consider it to be similar to space. Think of a what might have existed prior to the Big Bang. There could've been a primordial universe which had 4 dimensions, possibly more, with no specific direction of time. Then the Big Bang explosion happened. Also, don't think of the Big Bang as an explosion but more like a jet of water through a hose. The jet went along one of the 4 dimensions of this primordial universe, and this direction became what we call time. The remaining 3 dimensions are still free for us to move in, but we have no choice but to ride the jet of the 4th dimension wherever it takes us. Yousuf Khan |

Yousuf Khan I understand from this that you were there in the big bang and did see all this? How come you survived such a big bang? You must be very old? Or else how do you know all this for sure?

Take whatever explanation that I already gave you, either the explanation about the Planck units, or the experimental data of the MM experiment. Yousuf Khan |
