From: Michael Moroney on 16 Apr 2010 17:29 > Why do I need to rebut what SR says? You keep saying there is an absolute frame. SR states there is no absolute frame. If you're going to stick to your claim, you're going to have to rebut SR.

However, every inertial frame adopt the laws of physcs of the absolute frame. ______________________________ But you said above (and I quote) that "no inertial frame is the absolute frame". Therefore the absolute frame is *not* an inertial frame. If the absolute frame isn't an inertial frame, then what is it, according to you?

An Observer is at rest with respect to herself. Speed of light appears isotropic TO ALL observer, including the observer's frame. All clocks moving WRT the OBSERVER'S frame show time dilation as predicted by special and general relativity. All rods moving with respect to the OBSERVER's frame would be foreshortened in the direction of radial motion as predicted by special and general relativity. Relativity makes NO use of special frames, as all frames are relative. Ever wonder why it's call "relativity"? Seto--You really need to sit down and learn special relativity. There has never been an observation that contracts a prediction of special relativity. It remains a very fruitful theory and you should take the time to learn it, Seto. 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 |
