Derive Lorentz Transformation by Visualizing Space-Time Coordinates

[Ryder Rude]

It's simply unnecessary to assume FTL. Especially since these FTL frames are disallowed by the Lorentz transformations that have been deduced. Try here, for example:

https://en.wikipedia.org/wiki/Rapidity

I read somewhere that Lorentz transformations actually disallow matter being accelerated to FTL. Particles which are already moving FTL can still be hypothesized. Here are some related links:

It is stated that these particles would cause causality problems, but that wouldn't be the first time the universe defied our everyday logic.
