what if time travel was possible using cryogenic freezing and a remote scripted wave that will reactivate the time vessel
for example tom gets in his time machine and the machine goes to where in the past a radio wave will pass it and reactivate it now the only way they radiowave will reactivate it is if time works in a loop so he is there when the universe in a way restarts and the radio wave hits the time machine that has been sitting in space for eternity and reactivates there instant time travel only problem is time has to repeat it self for eternity
