519:" is an excellent description of optical effects. The only thing related to the animation however is the two-image explanation. As the object travels light is "dropped off" and travels towards us at the speed of light. Once the object passes, the older and new light arrives. But of course the entire sequence is is sub-second and a complete fantasy on multiple levels.

I don't understand the two images, what velocities are shown, the amount of
Doppler shift. This can't be anything like what a "tachyon" would "look" like even if it was an emissive sphere. If it were Earth sized and coming directly at you, the point of light would fill your visual field in about a

The opening paragraph of
Knowledge's article on Tachyons needs to be challenged. Causality is not a fundamental law of physics. It is a consequence of Special Relativity applicable only to particles that travel slower than the speed of light. The whole idea of "grandfather paradox" is based upon

I gather that this is not a "tachyon" but rather a uniformly emissive (but transparent?) sphere . The visualization shows
Doppler shifted frequencies in colors on a surface corresponding to Lorentz transformations of the sphere. That's why the colors are reddish to the left and bluish to the

to have travelled faster than light. The most obvious explanation for this anomaly was always inaccurate equipment. Probably no-one at CERN reported that the particle had actually broken the law of special relativity. Shouldn't we change the text accordingly?

The image is fun, but meaningless. What are the axes here? the bold lines? The colors? The meaning of the shapes? What of there velocities? How can we see a "tachyon" if tachyon's do not exist?
