Tubes in space could reduce space travel costs

It looks like space travel could become cheaper, if US scientists can accurately trace the twisting "tubes", which could heavily reduce costs.

These "tubes" consist of gravitational forces, which were created by the pull between planets and moons. They could help keep spacecrafts on track adding quicker more efficient travel.

Professor Shane Ross, from Virginia Tech explained to the Telegraph: ''Basically the idea is there are low energy pathways winding between planets and moons that would slash the amount of fuel needed to explore the solar system.

''These are freefall pathways in space around and between gravitational bodies. Instead of falling down, like you do on Earth, you fall along these tubes.

''Each of the tubes starts off narrow and small and as it gets further out it gets wider and might also split. I like to think of them as being similar to ocean currents, but they are gravitational currents."
