Special Relativity
Is $\displaystyle t$o always the stationary frame of reference (on earth), and $\displaystyle t$ the frame of reference moving relative to the stationary frame?
this is how my teacher explained it but I went to some websites that say the contrary.
And what if there is a question like "a man 6ft. tall boards a spaceship, that travels at .65c, how tall would he be on earths frame of reference."
what would be t and what would be to?
Thanks.
