Vast quantities of energy
Even if it were possible, faster-than-light travel would still take an enormous amount of energy. It would consume the entire mass of Jupiter to move a spaceship 10 m at warp speed, the researchers said.
"That is an enormous amount of energy," Cleaver said. "We are still a very long way off before we could create something to harness that type of energy."
Theoretical physicist Peter Bouwknegt, from the Australian National University in Canberra, said that though travelling at speeds faster than light is an idea which "a lot of people would find hard to swallow" the new research "stems from serious physics".
He said that while the idea that space-time itself can travel faster than the speed of light was a real possibility, he was sceptical about whether you could move spacecraft at faster-than-light speeds.
"It would turn the whole of physics around and there would be a whole lot of consequences – things like causality would go wrong," he said. "When people make calculations in M-theory they necessarily make assumptions about the behaviour of the theory in certain limits – whether or not the assumptions are valid remains to be seen."
Science of physics in highspeed travel
It seems that the universe has some secrets as man ,and high tecnology have opened some doors that unlimit the old limitations.
Dark Energy Engine
I think what we are trying to do is pass Dense non-baryonic matter through a variable magnetic field. This process would impulse the dark matter as thrust. This is simple.
Dark Energy is the media with which energy is calculated or absorbed. I write about this in my blog.

faster than light travel
We all have seen the tv show stargate.The space vortex that travels much greater than the speed of light.In another aspect this may work different than most people believe.Lets think of advanced space travel like travlin on a train.It comes in two parts.A energy beam than travels much faster than the speed of light and a space craft that travels along this beam like a space train.A Mathamatical question for everyone to solve.If the closest star is four and ahalf light years away,how fast would you need to travel to compleate this trip in four and ahalf minutes.
