Is really possible to make TIME MACHINE.If one can have velocity of Light?
“IF” is hateful word, often precede impossible statement, it do that here, no object made of matter can travel at velocity of light, inertial mass increase exponentially at high velocities, become infinite at speed of light, is impossible accelerate infinite mass, not all energy and all matter become energy of universe can accelerate infinite mass, also length at direction of travel shrink exponentially, that mean at velocity of light material object have infinite mass and time intervals and zero length and time passage, if have zero length that mean object spread over infinity, I think that hurt human. At velocities exceed light mass, length, time passage and time intervals become imaginary, i.e. products of “i” is square root of minus one, many people not do math here, they wrongly claim time go backward at ultra-light velocities, actually time, mass and length are all imaginary. You vastly oversimplify at question, show you not fully comprehend Theory of Relativity, many more people
