How fast are alcubierre drives?

A warp(Alcubierre) drive can go ~10c without being affected by time dilation. A space vessel can go up to but not as fast as the speed of light.

Is Alcubierre drive a time machine?

Alcubierre drive lets you go backwards in time, but only outside of the past light cone. That means that you cannot construct a frame of reference where the loop is closed.

Is a jump drive possible?

Jump Drive In theory, there is no limit to how far a jump can take a ship, but an incorrect calculation may result in a catastrophic collision with a planet or space debris. The Dune universe’s FTL, based on the fictional “Holtzman effect,” can also be considered a jump drive.

Is warp travel possible?

If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction. In Issac Asimov’s Foundation series, humanity can travel from planet to planet, star to star or across the universe using jump drives.

How does the Alcubierre drive work?

Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination more quickly than light would in normal space without breaking any physical laws.

What is an FTL drive?

Galactica’s FTL drive. The FTL Drive is the propulsion system used by human and Cylon ships to achieve faster-than-light travel through space. Prior to a jump, the drive is “spooled up” and then the ship “jumps” to another point in space.

Are wormholes faster than light?

Wormholes might allow effective superluminal (faster-than-light) travel by ensuring that the speed of light is not exceeded locally at any time. While traveling through a wormhole, subluminal (slower-than-light) speeds are used.

Will FTL travel ever be possible?

If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction. In Isaac Asimov’s Foundation series, humanity can travel from planet to planet, star to star or across the universe using jump drives.

How plausible is the Alcubierre drive?

The Alcubierre drive is theoretically plausible. It is a mathematically correct solution of the Einstein field equations. Its main problem is that the warped path through spacetime for its trajectory has to be set up before it travels. This makes it more like a FTL railway train than an independent vehicle like a spacecraft.

Is an Alcubierre-type warp drive possible?

Nevertheless, an Alcubierre-type warp drive might be realized by exploiting certain experimentally verified quantum phenomena, such as the Casimir effect, that lead to stress–energy tensors that also violate the energy conditions, such as negative mass–energy, when described in the context of the quantum field theories.

Can the Casimir vacuum fill the negative-energy requirement for the Alcubierre drive?

At the close of his original article, however, Alcubierre argued (following an argument developed by physicists analyzing traversable wormholes) that the Casimir vacuum between parallel plates could fulfill the negative-energy requirement for the Alcubierre drive.
