It is possible to see Star Trek-style 'warp speed' space travel in reality, said an astrophysicist in Australia. However, Professor Geraint Lewis is unsure if human will be able to come up with a warp drive to make high-speed travel between galaxies a reality.
Lewis, from the University of Sydney, said the concept was actually part of Albert Einstein's Theory of Relativity. Scientists need to find negative density energy in order to find a warp drive.
It's no more a secret that materials required to achieve the futuristic goal exist in the universe, but it is still not certain whether scientists could get them together and build a warp drive.
"Empty space itself has a negative energy density. The big question is if we could mine it and shape it, we would basically have a warp drive there and then, but we just don't know if that's possible", he added.
The biggest problem is speed because even travelling at the speed of light will take four years to go to the nearest star and 2 million years to go to the nearest large galaxy.
These distances are big constraints in colonizing the universe, so a way needs to be devised to beat that speed limit. Einstein's theory of relativity holds the answer to the mystery - a negative density energy. It will help build a warp drive for sure.
Material is currently not in hands of scientists, but there are signs that these are actually present in the universe. Lewis said that a lot would be known about the universe in the next 100 or 1,000 years, which increases the hope for making the hyper-fast travel a reality.
