Alcubierre Warp Drive – A Doomsday Weapon?


Is the Alcubierre warp drive a doomsday weapon or our passport to the Universe?

The Alcubierre warp drive is a theoretical tool that would allow for spacecraft to travel long distances in space rapidly, by deforming the space-time continuum in a bubble around the spaceship.

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

“It sounds like it’s straight from science fiction, and in a way it is, as the Alcubierre warp drive is a theoretical solution to the problem of travelling the huge distances in space in a reasonable amount of time.

But unlike science fiction, the Alcubierre warp drive completely obeys Einstein’s general theory of relativity,” said Professor Geraint Lewis of the University of Sydney’s School of Physics.

“All innovations start with theory, however, so these calculations contribute to our understanding of how such speeds could be achieved.Our team decided to consider what would happen to particles and radiation that a spacecraft, travelling in a bubble created by the Alcubierre warp drive, would come across as it travelled through space,” explained Professor Lewis.

“What we’ve shown is that when this spacecraft decelerated to arrive at its destination, it’d release high energy particles which would destroy anything near the spacecraft’s landing spot.”


While scientists have examined how it’s theoretically possible to create a bubble around a spacecraft with the Alcubierre warp drive compressing space-time in front of the bubble and expanding it behind the bubble, there has been little consideration of how this high-speed bubble would interact with particles of matter and light.

“Our calculations show that particles that come in contact with the warp bubble can get caught up and congregate in front of the spacecraft, and some particles even enter the warp bubble,” said Professor Lewis.

“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.

Also, during the journey, the particles picked up and included inside the bubble could threaten the safety of people travelling in the spacecraft.”

Brendan McMonigal said, “Interestingly, the energy burst released upon arriving at the destination does not have an upper limit.

You can just keep on traveling for longer and longer distances and the energy that will be released will continue to increase – one of the odd effects of General Relativity.

This is what a warp drive spaceship looks like

“Even for very short journeys the energy released is so large that you would completely obliterate anything in front of you,” said Brendan.

“It seems that human exploration of the universe will have to wait until we’ve worked out how to avoid the destructive deceleration of a spacecraft in an Alcubierre warp drive bubble.”

While the study may seem like a fun theoretical consideration, exploring the implications of Einstein’s theory of relativity is significant and has all sorts of practical uses, such as relativity correctors for GPS systems, found in virtually all smart phones, that correct for the time difference between the ground and satellite.


Is it possible the Alcubierre warp drive can be a doomsday weapon?

“We didn’t look at the full 3-D effect of the bubble, so we don’t know if when you stop the drive if it sprays off particles in all directions or if it’s just a very finely collimated beam, but we do know it will throw off beam of high-energy particles,” said Lewis. “So we don’t know [yet] how much to the left or the right you need to stand to be safe!”

    First off Alcubierrre warp drive metric won’t work because of the amount of energy it requires to make the negative energy and the proximity of the bipolar gravity fields or space fields. The fields would collapse and produce a singularity a (black hole). The fields have to be farther apart and this amount of negative energy is not required. In fact the newer models only use negative energy potential to normal space. The front field will be a false vacuum state this requires less energy and less particles than normal space. The strongest part of the field is miles from the ship and to the center of the field. The only way to do this is to draw the particles to the ship. The area around the ship is a flat space bubble the ship is at rest mass. The space behind the ship expands out from the bubble. It is a false vacuum state also but with higher energy than normal space. The field matrix is shaped like an hour glass with the flat space bubble in the middle. Anything outside of the fields move at normal speed. The field matrix is an unnatural energy system when the fields are turned off everything goes back to normal. The speed particles where moving in the bubble is now the speed those particles are moving in normal space. At warp it is not particles are the ship that is moving faster than light but time space. At warp the particles drawn to the ship should be collected and used to help generate power. In other words the particles should end up in the warp drive engine. Professor Lewis is looking at matter going faster than light and it is space going faster than light there is a difference. The ship doesn’t decelerate it is not moving. The space around the ship stops because the unnatural energy condition equalizes. The particles move according to their energy they will not be moving faster than light. Now as to how to generate a false vacuum state in front of the ship why not use the quantum phase shift, from the Bohm-Aharonov Effect manifested as the Lorentz force. Space has free electromagnetic fields
