 We all know that photon is a mass-less and charge-less particle. It moves with the speed of light that is 299792458 m/s. According to Einstein's theory of special relativity if an object moves with the speed of light consistently in a straight line, then it can travel in the time. Anybody who can travel in the time can change history and solve the mystery. Thus to make a time machine we have use photon, as an engine as well as fuel. To tow the wagon which will be developed by opaquest and the lightest material. For this, we need an enormous amount of photons. Then we might be able to travel with them with the speed of light. For this firstly, we have to find a way to trap the photons.  Time travel might be subject to the risk of existence, life and age of any individual or object.
