# Relative Velocity | Artificial Gravity | Controlled Time Dilation

 By: Daniel Nase
 Velocity is the change in distance over the change in time. Relative velocity from a traditional point of view often talks about travelers on a train. Lets say the train is moving forward at 100 mph and you are running towards the front of the train at 5 mph. Your actual velocity relative to the Earth is 105 mph.This is different. Imagine you are an astronaut traveling at near the speed of light. Space and time are bent around your ship as its mass and energy increases. You see the stars fly past your window as if you were on an episode of Star Trek, but there is a big problem back home. The real reason the stars are flying past your windows is because you are experiencing significantly less time, and you are not actually going faster according to the outside world. This is represented by relative velocity equals the change in distance divided by relative time. The only way to counter act the effects of relative time at home are to increase the gravity around and inside the Earth while keeping the net gravitational force the same at the surface. This can be accomplished by accelerating particles at near the speed of light until they become extremely massive and bend space both inside the Earth and a satellite network of accelerators around the Earth. As long as gravity is kept in balance, no one on the surface would notice a change. The accelerator can also decrease the speed that the particles are circulating to return space-time to normal in the event of an emergency.
