Sydney: Space travel could be the ultimate in human adventure but there`s a catch - it could thrill but also kill and destroy everything within sight.

It could create the ultimate `killer entrance`, devastating your destination and anything around the landing craft, according to calculations by Geraint Lewis and two honours students from the University of Sydney.

The Sydney team is the first to spell out on the effects of theoretical space travel using an Alcubierre warp drive, the journal Physical Review D reports.

Miguel Alcubierre, Mexican physicist, proposed this warp drive in 1994 as a way to travel faster than light, overcoming the limit on particles travelling at such speeds posed by Einstein`s theory of special relativity, according to a Sydney statement.

"When the spacecraft decelerates to stop at its destination, the particles collected at the front of the spacecraft are released with such high-energy that they would destroy anything they came in contact with," said Lewis, professor from the Sydney School of Physics.

"During the journey the particles picked up and included inside the bubble could threaten the safety of people travelling in the spacecraft," added Lewis.

"What we`ve shown is that when this spacecraft decelerated to arrive at its destination, it would release high energy particles which would destroy anything near the spacecraft`s landing spot," concluded Lewis.
