Re: A Geometrical Proof of the Non-invariance of the Spacetime In terval

If I understand you correctly, you say that F' claims breakfast occurs in
his stomach and lunch occurs in is stomach.

But where is his stomach?

In what city do the two people F and F' say breakfast occured in?  According
to SR (special relativity) in your opinion?
