I think there is a more simple method to proof that, matter (or energy ) can't travel through the time.¶
It is forbidden from the law of conservation of energy (CE).¶ According CE a closed three dimension space contains the same total of Mass and Energy, any time ( trace to fourth dimension).¶

For example, if I (or a photon) will travel when i was young in 31/12/1980, next day universe's energy will not be the same with 1980¶.
