Can it be? A German university tried it.
Traveling faster than light would mean reaching places in the universe that today are impossible distances for us. Even the Alpha Centauri star system, the closest to ours, is too far away for us today. But there is a detail to consider, modern physics, theorized by Albert Einstein, says that it is impossible to reach the speed of light. Recently a study by physicist Erik Lentz of the University of Göttingen in Germany, however, could have a viable solution to the dilemma that does not involve an alternative physical system to the one we have accepted today. Lentz will require a new class of hyper-fast solitons — a type of wave that retains its shape and energy while moving at a constant speed (and in this case, a speed faster than light). According to his calculations these solutions may exist within general relativity and come exclusively from positive energy densities, which means that it is not necessary to consider exotic sources of negative energy density that have not yet been verified.
“This work has moved the faster-than-light travel problem one step away from theoretical research in fundamental physics and closer to engineering” Lentz said.“The next step is to figure out how to reduce the astronomical amount of energy needed within the range of today’s technologies, such as a large modern nuclear fission power plant. So we can talk about building the first prototypes”.
