Jimmy How it works? My time machine "The Light Speed Eagle" is only capable to go to a future date and it almost completely relies on mathematics to get it there. For example if you wanted to travel four years in the future you would multiply four times the distance of a light year. (5,869,713,600,000) Just so you know a light year is the distance light travels in one year, so if light travels at 186,000 miles/second then the solution for finding the distance that light travels in one year would be… 186,000 x 60 x 60 x 24 x 365.25 This mathematical problem equals 5,869,713,600,000 or the distance traveled by light in one year. The reason you would have to know about light speed and light years is because it time equals distance so if you would travel a four year journey in 7.8 seconds (which is how long it would take you to travel four years distance at light speed) you would arrive back at earth… only the four years that you skipped would pass on earth making you four years ahead of time. But there are some other things that I did not mention, for instance in order to get back home from you light speed journey you would have to turn around at two years distance or you will go farther in time than you expect. Plus half way to each two-year distance you would have to reverse your engine or you will fly passed your stopping point. The only way I believe you can create this power is through nuclear fusion also known as nuclear energy. I first though that I would fuse hydrogen and helium like the sun does…but then I though it would take up too much space because of a reactor's gigantic size. So I decided to choose another course of action. An atomic reaction would power my massive ship into the future. In a super-strong titanium prism one piece of pure Plutonium will be forced and held together causing a controlled atomic reaction that will be released in several bursts. This will power my ship to the speed of light. The space ship will also have two R2 space engines for maneuvering at low speeds. Another problem would be navigating at light speeds, easy solution…an on board super-computer would plot a course even before the ship moves so that any navigational movement will be handled by the computer. The ship will be created in earth's atmosphere because it is harder to lunch from earth than it is from space. My ship is NOT designed to enter earth's atmosphere so an X20 or a free-fall spacecraft will descend to earth from the "Light Speed Eagle". Problems like G-force are actually no problem at because by the time the G-force multiples your journey is all ready over. If you have any questions about the "Light Speed Eagle" or time travel please ask me. This was a project assigned in science class, we had do draw a time machine...but i went a little farther with it. Please Give me your input.
