Well the spatial dimensions in special relativity is all ****ed up.

Sounds like a rock song from the 50s.

Special relativity, like general relativity uses the three observed

as well as the modern physics theories, such as QED, enjoy the fact
that there has never been an observation that contradicts a prediction
of those theories.
