I characterized how, in inertial reference frames, the Newtonian laws of mechanics and the laws of electrodynamics hold. I also described how the laws of physics would be different in an absolute reference frame. The properties that YOU think are ascribed to an absolute reference frame are incorrect. Those are not the properties of an absolute reference frame. Since we have found no reference frame in which the laws of physics are different than what they are in inertial reference frames, in a manner that singles out a velocity with respect to an absolute reference, we have no evidence for an absolute reference frame at all, despite searching for one experimentally. In special relativity, the absolute reference frame is explicitly said not to exist. > > > > > > Ken Seto > > > > > > Ken Seto- Hide quoted text - > > > > > - Show quoted text -- Hide quoted text - > > > > - Show quoted text -- Hide quoted text - > > > - Show quoted text -- Hide quoted text - > > > - Show quoted text - > >

No, Ken, what YOU think are the properties of an absolute reference frame, are NOT the properties of the absolute reference frame. You are simply mistaken about that. "Absolute reference frame" has a very specific meaning in physics, and it is not the meaning you attribute to the term. > > - Hide quoted text - > > > > > - Show quoted text - > >

How can I describe the difference between something and something that does not exist? What's the difference between a rabbit and the Easter Bunny? OK, here it goes. An inertial frame is a frame that describes motion and interactions without any fictitious forces. All inertial frames are in constant motion (no acceleration) with respect to each other. An absolute frame is pink with purple polkadots and is invisible. It is soft and fluffy with razor-sharp teeth. It has magical powers on the third Tuesday of every month, except during a full moon. >> I'll give you a fourth chance to prove me wrong.

You can't. >You can't give me a reference where Einstein said that the absolute >frame doesn't exist. Just as I thought. You can't give any reference where Einstein claims any absolute frame exists. That's because it is you who created the idea that an absolute frame exists in SR, not Einstein.

I don't know, as that's a general definition. An absolute or preferred frame has *some property* (some law of physics) that's identifiably different from other frames. Something that makes it special. http://en.wikipedia.org/wiki/Preferred_frame An example is the once-theorized frame where the aether wind was stationary. > Is the speed of light in the absolute frame not >isotropic c? Which absolute frame of which theory? Maybe you can tell us what it is about this absolute frame you keep talking about that makes it special, and thus "absolute".

Neither are absolute in any sense. Seto, you come along with your fabrication of "Absolute frames" and we all think you are bonkers. And this has been going on for more than a decade. It appears that you never learned special relativity and your posting record keeps verifying that. Furthermore you call most of us idiots and puppy chow eaters. All we are trying to do is to get you to sit down and learn special relativity. It is a beautifully fruitful theory that accurately describes many phenomena of nature. There are even Physics FAQ about special relativity. What is the experimental basis of special relativity? http://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html How do you add velocities in special relativity? http://math.ucr.edu/home/baez/physics/Relativity/SR/velocity.html Can special relativity handle acceleration? http://math.ucr.edu/home/baez/physics/Relativity/SR/acceleration.html |
