Also, Professor Geraint Lewis wrote an accessible article about Alcubierre warp-drive spacecraft and galactic exploration. theconversation.com/… He suggests warp-ships might sterilise planets. Sensible protocols can be devised to avoid such accidents. | |

As stated previously the paper I read (if I can find the reference I will post it) indicated a very high figure for energy accumulated in transit. For the sake of fiction I simply took the liberty of assuming that if the amount of 'negative' matter/energy needed to generate an AD drive in the first pace was currently open to speculation then for arguments sake so is the amount of energy accumulated in transit. | |

The notion about the amount of negative energy/mass needed for an Alcubierre warp is potentially huge, so de-warping might convert that into something nasty. However, practical Alcubierre drives would need ways of working with less. There are papers about Alcubierres with reduced negative energy. | |
| Jun 9, 2020 at 2:59 | comment | added | Mon | The report I read had calcs showing that potentially huge amounts of energy would be released. But then there is also argument over how much negative energy/mass you would need in the first place to create one. So play around till you have something that works for the story | |
| Jun 9, 2020 at 2:43 | comment | added | a4android | The energy collected by an Alcubierre drive is accumulated on the bubble & not in the bubble. It is released as a pulse when the bow-wave / shock-wave is no longer restrained by the warp bubble. The blast won't be civilization-destroying. Merely the equivalent of a largish nuclear weapon. This can be calculated by assuming interstellar matter is convertedin to energy & knowing the density of interstellar gas, the frontal area of the warp, & the distance travelled. | |

Corrected spelling, & it is "its" not "it's" which is ALWAYS the abreviated form of "it is" when used correctly.
