What is this incoherent rambling about the LCH and stock trading?
Measuring particle accelerators by length doesn't make sense, and I highly doubt that particles in the LHC travel faster than microwaves in air.
- TeMPOraL 11y ago> I highly doubt that particles in the LHC travel faster than microwaves in air Particle beams in an accelerator travel in (near)vacuum. Speed of light in a medium is lower than in vacuum. In particular, the speed of light (and hence microwaves) in air is around 0.999723 c (per [0]), which is less than 0.999999 the article says about speeds in LHC.

- j-pb 11y agoThe refractive index is inversely proportional to the wavelength though. And according to the linked papers that happens to be ~25mm (11ghz) to ~50mm (6ghz). Wolfram alpha doesn't even have valid answers in that range. Only between 400 and 1200nm.
- TeMPOraL 11y agoGood point, I didn't knew that. Given how much trouble I'm having finding a relevant index for microwave range, I'm going to assume equal probabilities to the following statements: "microwaves in air indeed move slower than particles in LHC" and "the author just used n=1.0003 for microwaves in air".
- jheriko 11y agothey don't, but they also don't collide with air and interact with it... thats the key difference.
