We know that Light is the fastest thing. How then can we beat light in a race? For sure we can't beat it in running. Perhaps a machine will do it. Scientist believe that we can go back in time IF we can pass the speed of light. Do you believe that we can create a machine that will help us go back in time? IF we can, how will the machines look like? How big will it be? What will it made out of? How much would it cost to create one? What kind of energy will it use? Where will we put this machine? Public or Private Lab? IF there's a time machine, surely we would want to sit in it and set the date. Then press the "travel" button. The question I have is... will the machine stay in one place yet at the same time carrying you into the past? How can a machine beat light in a race by sitting in one place? I find that mind-boggling. Or maybe we're going to shoot this ball or whatever shape it is into space hoping that it will go faster than the speed of light then it slow down and go back to earth, falling down and crushed some tall building? And then you walk out and have cops all over you because they think you're an alien from another planet? Who will use Time Machine and for what purpose if it's possible? Another question is: IF the past cannot be change, then what's the point of going into the past? Is traveling faster than the speed of light just a "dream"? IF such machine exist then Light is no longer the fastest thing in the universe! The Machine will be! So far no one knows what will happen for sure once we go past the speed of light. One theory say that we will go back in time and currently scientist are working to turn that theory into fact. hmm... is there such thing as a timeless zone (universe?) what if we enter such zone once we go past light? or even vanish and disappear?
