Scientists want to develop technology which can be helpful in space travel. Today we are not capable to travel a long distance in space to explore it. Scientific research is going on to develop technology or idea that makes our space travel possible. There are many difficulties we have to face in space travel but the most one is to travel with speed of light. According to Einstein's theory of special relativity, only massless object like photons can travel with speed of light or we need infinite amount of energy to make it travel with speed of light. Scientists develop some idea to make it possible in other way round.
Warp drive is one such fictitious idea which allowed a space travel at speed of light. This technology will make the space-time to expand and contract itself and generate warp fields to form a subspace bubble that envelop the manned-spacecraft. Space-time will be warped around the spacecraft which will accelerate to travel it at speed of light.
spacecraft will not be warped as it will stay inside the subspace bubble.There will be no time dilation (slowing down of time for the object traveling with speed of light) for the spacecraft as the spacetime will drive it, warping itself at the speed of light. This device would need prohibitive amounts of energy roughly equal to the mass-energy of planet Jupiter.
This technloogy is theoretically described on papers but can be possible practically if we really want to travel to other stars because 'where is a will there is a way.' Scientists and researchers are trying their best to develop such technology that will make our space travel real and possible in upcoming years.
