Contraction Definition and 709 Threads

As a mass moves faster through a sea of Higgs particles, it gathers more around itself and increases the density of Higgs particles. This increased density of Higgs particles makes it more unlikely W particles in the vacuum will have the energy to get to a neutron, let’s say, and to cause a...

My question is rather simple: Are there experiments where they have measured length contractions?

This is a theory of mine. It proposes that there is no space-time in which masses and particles move at some speed; rather, what we have is a series of pulsating contractions which move at the speed of light and generate the illusion of space-time because of their spherical symmetry. This...

In Einstein's SR the velocity of the light (c) is same in every referent frame. Let us for instance assume we don't know its exact value and try to estimate it. The relative distance suffers contractions depending on the velocity of the frame like this: L=L_0\sqrt{1-\frac{V^2}{c^2}} where L0...

suppose you had a planet with a train going all the way around the circumference. The train is a complete loop so you just have an endless train. now speed the train up to near c. Because of length contration would the train begin to squeeze the planet?

If I was traveling close to the speed of light and passed a hotdog outside, the hotdog would appear smaller to me compared to the hotdogs I remember eating on Earth correct? If I was traveling close to the speed of light with a hotdog in my hand and held it right in front of my pants, as I...

I don't recall seeing this derivation anywhere but its probably somewhere in the relativity literature since most things are. A poster at sci.physics.relativity posted what he thought was proof that the Lorentz contraction doesn't exist. See the Fig. 1 in Lorentz Contraction - Version 2 --...

would some be able to give me an example that shows some evidence of length contraction? i have looked at the muons example, but it seem to be dependent on the time dilation effect, rather than being evidence of length contraction. thanks for any help.:) much appreciated. btw, feel...

This is a thread about physics law. Physical laws are supposed to be invariant under choice of metric units. The meter and the second, for instance, are arbitrary choices. If we had come upt with other units of measurements, the physical laws would be the same. But as to how far can this...
