A quote from an old thread reads "Energy is the time component of the momentum 4-vector"
That quote came from a Science Advisor.
Does this mean that time can be either a) substituted for energy in the momentum 4-vector, or b) seen as equivalent to energy in the momentum 4-vector? Hmm, maybe my a) and b) are the same. Regardless, the question remains. If the answer is "No," then is there a physics 4-vector that includes time? I say "physics" as to discern them from purely mathematical 4-vectors.
Also, when working with physics 4-vectors of the same sort, such as comparing physics 4-vectors of the same sort, do all the constituent vectors combine of a given physics 4-vector? If so, what are the operators of how they combine?
Thanks,
Jake
